Solar Street Light with Lithium Battery- Free Manual Guide
Solar Street Light with Lithium Battery- Free Manual Guide
These rechargeable batteries are used to store the electricity generated by the solar panels at sunrise in the solar LED street lights, which can control the energy consumption at sunset. Therefore, the type of battery used in general solar street lights is also an important information when choosing a bulb. When choosing a multifunctional solar street light, you can't just focus on the price. It is understood that lead-acid batteries, lithium batteries, and lithium iron phosphate batteries are three types of batteries that can be used for general-purpose solar street lighting. Integrated solar street light refers to a new generation of solar LED street light that integrates solar panels, batteries, controllers, and LED lights.Please confirm the local temperature extremes are appropriate for the above by choosing a street light. transportation time to avoid damage. The quality of solar street light batteries directly affects the quality of solar LED street lights. Controllers, solar panels, batteries and light sources are the main components of solar street lights.In order to reduce costs and attract customers, these products use false standard parameters, such as light sources, solar panels, batteries and electrode materials. If the light source is an LED, a special system is needed to remove the heat from the LED lamp. Since the solar panel of the universal solar street lamp is integrated in the lamp body, the angle of the lamp body must not only consider the problem of maximizing the amount of solar radiation received, but also consider the light distribution. Solar street light.When solar LED street light factories produce street lights, they will use high quality LED light sources produced by major brands. While converting LED street lights reduces the burden on this large energy-consuming industry by providing design, manufacturing and assembly services to each other, solar street lighting provides lower prices for these projects. Choose the right solar panels and battery depending on the wattage of the lamps, the required lighting level and the weather conditions. Solar panels or solar panels are designed to extract sunlight as an energy medium to produce electricity, light, etc.These cables are used to connect the battery compartment on the top of the pole, the LED and the solar panel. These panels are called photovoltaic because they are used to convert light energy directly into electrical energy.The energy stored in the battery is subsequently released in the form of direct current to power the LEDs for lighting at night. The use of sunlight minimizes the pollution of the environment resulting from the use of kerosene lamps in rural homes. Controllers available on the market these days include a charger, auxiliary power supply, LED lamp driver, microcontroller, and insurance circuitry. The battery can be recharged using the energy obtained from the solar panels at sunrise and taking into account that it charges the battery at sunset.During the day, solar energy is converted into electrical energy and stored in batteries. Now, the use of lithium batteries has been extended to the solar industry, replacing lead and gel batteries. When sunlight shines through the solar panel, the battery will charge and store electricity throughout the day. The principle of solar cells is that if the amount of light falling on the battery is more, it helps to generate more electricity.You can check out our How Sunlight Works article for more information. In rainy or cloudy weather, these devices will not charge to the optimum level. It is a convenient, economical, durable and modern way to illuminate streets and houses. This type of sunlight emits a wide beam of high intensity that covers a large area.Each time you press the button, the operating modes will change, while the light will flash. If not configured correctly, it will affect battery charging performance, shorten illumination time, and also affect detection performance, resulting in inaccurate auto power-on times. In fact, sphere integration can also help get even more electrical parameters such as illumination (brightness), light output, and so on.LEDs (Light Emitting Diodes) last longer and are more durable, so the device is worth your money. Typically used for emergency lighting such as power outages and nighttime activities. It then turns on the light automatically, so you don't need to worry about manually controlling it.If low-quality lithium batteries are used, they need to be replaced frequently after long-term use, resulting in very high actual use costs. All you have to do is use its auger and rotating rod to balance and fix the light. High-quality lithium iron phosphate battery with a service life of up to ten years. These fixtures are more common and easier to install than the other three.The color rendering index (CRI) shows how well a light source allows a substance to reflect its true color; the higher the CRI, the more an object can reflect its true color under that light source. Outdoor luminaires usually have an IP65 rating, which is the highest level of protection for outdoor luminaires, excluding underwater luminaires. Because these light poles are installed in harsh environments, the coating of the battery, equipment, and exterior surface finishes require extra care during installation. At the same time, keep it away from the shadows of the house, trees, etc.

Importantly, challenge-response pairs differentiate our protein-based PUFs from other common unique objects and tags29,63. In reaction to optical challenges, defined by a unique set of excitation and emission bands of different fluorescent proteins, the edible PUF made of silk protein (i.e., fibroin) and fluorescent proteins generates distinct output responses, which are used to extract digitized keys (Fig. 1a). The source of entropy is randomly distributed fluorescent silk microparticles seamlessly embedded in a covert thin transparent silk film. First, we take advantage of four different fluorescent proteins (i.e., eCFP, eGFP, eYFP, and mKate2) that have specific excitation and emission peaks in the visible wavelength range (Supplementary Table 1). Specifically, we utilize fluorescent protein-expressed silk produced by transgenic silkworms as recombinant proteins via the piggyBac transposase method (Supplementary Methods and Supplementary Fig. 1a). Silk proteins are an excellent biopolymer to be genetically hybridized with fluorescent protein genes46,55,57,59. Second, to fabricate fluorescent silk microparticles (Supplementary Fig. 2), fluorescent silk fibroin is regenerated into an aqueous solution with a low-temperature process, is freeze-dried, and is gently ground into zeolite-shaped microparticles with sizes of 99.3 7.9 m (mean standard deviation) (Fig. 2a, b and Supplementary Fig. 3). Third, an admixture of the fluorescent silk microparticles is broadcast on a large flat surface and a white silk fibroin solution is poured on top. After an ambient drying process in the dark, this thin transparent silk film with a thickness of 150 m is punched into 7 7 mm2 squares, resulting in all protein-based edible PUF devices (Methods and Supplementary Figs. 2 and 4). eCFP, eGFP, eYFP, and mKate2 silk cocoons possess bluish, greenish, yellowish, and reddish colors under white light illumination (Supplementary Fig. 1b). However, after the regeneration of the fluorescent silk, each type of fluorescent silk microparticles are not distinguishable in the naked eye, while maintaining their fluorescent properties (Fig. 2 and Supplementary Fig. 5). This fabrication process is scalable for mass production without using any sophisticated equipment and is safe for oral consumption without any organic solvents or synthetic polymers (e.g., methanol, ethanol, isopropanol, or polyvinyl alcohol) (Methods and Supplementary Fig. 6a). Analyses of mass spectroscopy, energy-dispersive X-ray spectroscopy, and in vitro cytotoxicity (cell viability test) assays support the overall nontoxicity of the edible PUF devices (Supplementary Methods and Supplementary Figs. 7-9). In Fig. 3, the flow diagram illustrates how a cryptographic key is extracted from an output response when challenged by a set of excitation and emission bands, including the raw output measurement, the bitstream extraction, and the final digitized security key. We mainly use four representative challenge-response pairs (n = 4) based on the excitation and emission peak wavelengths of the individual fluorescent proteins in silk (Supplementary Table 1 and Supplementary Fig. 1c). An input challenge (C ) is selected as a combination of the excitation and emission bands at specific wavelengths such as = 415 nm and = 460 nm; = 470 and = 510 nm; = 470 and = 560 nm; = 530 and = 630 nm, corresponding to eCFP, eGFP, eYFP, and mKate2 in silk, respectively. Upon optical excitation, a raw fluorescent image is recorded by a charge-coupled device (CCD) camera equipped with a conventional zoom lens via a tunable color filter (Methods and Supplementary Fig. 10a). In other words, the corresponding fluorescent image acts as an output response (R ). A resultant digitized key (K ) is obtained by an extractor that converts the fluorescent image of silk microparticles to a binary bitmap (Fig. 4). First, to improve the quality of binarization, we normalize the raw fluorescent image (300 pixels 300 pixels) by the maximum intensity (Fig. 4a). The noise is removed by applying a threshold of 20%. Fluorescent areas smaller than a specific pixel size of 20 are also considered as noise. Then, the image is resized to be 150 pixels 150 pixels with a binning process. Second, to ensure a low bit error rate (high reproducibility), we find the spatial peak position of each fluorescent silk microparticle where the highest intensity peaks of the microparticles are located, subsequently reducing the image size to 50 pixels 50 pixels (Fig. 4b). Then, the peak positions are only assigned to 1 bits and other pixels are 0 bits. Third, to remove the bias of 0-bits, we apply an enhanced version of the von Neumann bias compression algorithm with two-pass tuple-output debiasing (Fig. 4c)64. Because the fluorescent peaks are relatively rare events in the entire image due to the density of the fluorescent microparticles, global bias is present such that 0-bits are generated consistently more often than 1-bits. Finally, after debiasing, we use first 64 bits as a digitized key in each response, because a typical minimum number of peaks in the fluorescent images is 32. Combining four challenge-response pairs (n = 4) together, the final digitized key size results in 256 bits (=4 64). We assess the quality of randomness of the edible PUF-generated binary sequences, using the NIST statistical test suite that was originally designed to evaluate random and pseudorandom number generators65. One of the minimal requirements of PUFs is randomness with high entropy, as PUFs rely on an entropy source to create an unclonable output response66,67. When PUF responses are used for cryptographic key generation, it is also critical to evaluate the randomness to ensure the unpredictability of the keys generated by PUFs. The NIST statistical test suite includes 15 different tests to quantify the randomness of bitstreams. Each test focuses on a specific aspect of randomness (Supplementary Table 2). Some of the tests rely on the minimum sequence length of 1 106 and the minimum number of substrings (blocks) of 55, requiring a total stream of 5.5 107 bits. On the other hand, the key size of the edible PUFs is significantly shorter than those of random number generators. To use seven statistical tests that require a reasonable stream length, we explore the randomness of binary sequences summed from 30 different PUFs (Fig. 5). Specifically, we collect a total of 7680 bits from 30 different PUFs (256 bits for each PUF) and divide the bitstream into 60 sequences to perform each statistical test 60 times on individual 128-bit long sequences (Supplementary Dataset 1). Each statistical test returns two results; a p-value of a chi-squared (2) test and a pass rate (i.e., proportion), as shown in Table 1. As summarized in Table 1, the binary sequence from the 30 different PUFs passes all of seven NIST randomness tests without any post-processing. The parameter values used in each test and the characteristics of the NIST randomness tests are summarized in Supplementary Table 2. In other words, the bitstream (7680 bits) extracted from the 30 PUFs is statistically random, supporting the idea that the output responses of all protein-based PUFs can be unpredictable and unclonable. This result also supports the idea that our simple broadcasting process of particulate fluorescent silk offers a random spatial distribution as a straightforward yet effective entropy source60,61. To evaluate the basic PUF performance, we examine the digitized keys of the edible PUFs. We first estimate the bit uniformity by checking the equal probability of observing 1-bit or 0-bit states: where K is the lth binary bit of the key and s is the key size. Basically, the bit uniformity is the Hamming Weight (i.e., number of 1 bits in a binary sequence) of the s-bit key. For 30 different PUFs, the distribution of bit uniformity converges to the ideal value of 0.5 (Fig. 6a). Then, to evaluate the device uniqueness of each PUF, we calculate an inter-device Hamming Distance (HD) by counting a number of different bits between two PUFs under the same challenge. The device uniqueness measures the degree of correlation between digitized keys measured from two different PUFs. Ideally, the digitized keys from any two selected PUF devices should be uncorrelated, indicating that the state of a PUF is unknown even when the states of other PUFs are known. The inter-device HD between any two PUF devices can be defined: where K and K are s-bit keys of the ith PUF device and the jth PUF device among q different PUFs, respectively. The 30 different PUF devices generate a total of C (=30 29/2 = 435) comparisons. In Fig. 6b, the histogram of the normalized inter-device HDs is well fitted into a Gaussian distribution with a center at 0.5032 with a standard deviation (SD) of 0.0458, which is close to its ideal value of 0.5, exhibiting the excellent device uniqueness of all of the edible PUFs. In addition, we investigate the degree of correlation among the digitized keys of four responses in each PUF by calculating an average HD (Fig. 6c). The 30 different PUFs result in a mean HD value of 0.499 with a SD of 0.0041, indicating that the individual digitized keys in each PUF are also unique. When the number of challenge-response pairs is extended to seven, seven resultant digitized keys are still uncorrelated with a mean HD value of 0.5089 with a SD of 0.0766 (Supplementary Figs. 11 and 12). In addition, we calculate an encoding capacity of the edible PUF-generated binary sequences. The encoding capacity simply means a number of codes that can be generated and is defined as cs where c is the bit-level (c = 2 for binary bits of 0 and 1) and s is the key size38,68. To accurately estimate the encoding capacity, it is important to use an appropriate key size. When an imaging scheme is used, one may think that the total number of pixels (variables) is the digitized key size. In this case, the actual encoding capacity can be less than this nominal encoding capacity, because each individual pixel (variable) cannot be completely independent. One way for estimating the number of independent pixels (variables) is to analyze the degrees of freedom; s = p(1 p)/2, where p is the mean probability and is the standard deviation31,34. In Fig. 6b, the resultant width of the inter-device HD distribution shows that significant subsets of the key are mutually independent, corresponding to the degree of freedom (or number of independent variables) of 120 (0.5032 (1 0.5032)/0.04582). As a result, the edible PUF has c = 2 and s = 120, resulting in a relatively large encoding capacity of 2120 (1.3292 1036). Importantly, the debiasing process is useful not to comprise the actual coding capacity. If a security key is biased with too many 0 s or 1 s, the actual coding capability is often diminished. A large encoding capacity could be utilized to provide information on manufacturer-determined data, including dose information (e.g., dosage strength, dose frequency, and expiration date), manufacturing details (e.g., location, date, batch, and lot number), and distribution path (e.g., country, distributor, wholesaler, and chain). If a higher encoding capacity is required for a specific application, the key size of our edible PUF can simply be scaled by further optimizing the density of fluorescent silk microparticles, which allows for a larger number of peaks in each image. The number of challenge-response pairs can also be increased by incorporating additional combinations of the excitation and emission bands (Supplementary Fig. 11). To examine the feasibility for reliable PUFs, we test the readout reproducibility and stability of the security keys from the identical PUF device. The reproducibility of a PUF represents the ability of generating the identical keys following the same repeated challenges. We calculate an intra-device HD, which is quantitatively described by a bit error rate (i.e., percentage of error bits out of response bits with an ideal value of 0) from 10 challenge-response cycles (nine pairwise comparisons) for each PUF device. For the ith PUF device, an average intra-device HD captures the readout reproducibility: where K and K are the original s-bit reference key and a s-bit key extracted from the same PUF device at a different time-point t and m is the number of repeated measurements. Figure 6b shows a relatively low mean value of 0.0632 with a SD of 0.0164 estimated from the intra-device HD histogram for the 30 different PUFs at the same 10 challenge cycles. We further examine the long-term reliability under the same challenges after 60 days in the laboratory environment (i.e., stored at 22 2 C and 40-50% relative humidity in the dark) (Supplementary Fig. 13). When the fluorescent intensity of the raw fluorescent images taken 60 days apart is compared, the correlation coefficients (r) of the four responses (R , R , R , and R ) range from 0.833 to 0.983. For the pixel positions of the first 32 peaks in the binarized images, the r values are even higher than 0.895 for all of the responses. These results support the potential reliability of the protein-based edible PUFs, although the reproducibility assessments do not reflect extremely harsh conditions, given the medical applications. We further estimate a false positive rate and a false negative rate from the inter-device and intra-device variabilities. When PUFs are used for authentication, the false positive rate is the probability that PUF A is authenticated as PUF B. The false negative rate is the probability that a correct PUF fails to be authenticated. The resulting false positive and false negative rates are 9.6394 1013 and 3.0982 1012, respectively, assuming that the inter-device and intra-device variabilities follow Gaussian distributions (Supplementary Fig. 14). The pairwise comparison map of cross-HD analyses further shows that all of the 30 different PUFs are highly uncorrelated (Fig. 6d) where the diagonal line indicates the intra-HD values for the identical PUF device itself, while the off-diagonal points represent the inter-HD values compared with the other PUF devices.

How Do I Keep Rabbits From Chewing Electrical Cords on My Garden Lights?
Find something that they do not like of a kind of smell they do not like and put it around the places you do not want them to get near1. deciphering growing lights specificsThe important factors are the light spectrum and the lumens , not the watts. I have found more information for aquarium light products than garden lights . A metal halide ( not halogen ) with a 5000 C temperature rating would be good but use a lot of power ; available in wattage from 150 to 500 and maybe more.2. How to tell if solar garden lights are working?pat,solar lights are NOT connected to an electric outlet,they get their energy from the sun,sometimes you have to replace the rechargeable batteries in the lights,the best way to tell is by putting your hand over the solar panel on top of the light, the light should come on,if it does not you may have to replace the battery,and i do not think they make a battery charger for solar lights,hope this helps3. how do i get rid of earwigs in garden lights there only in the battery departments?After you clean them out seal the compartment with some sort of caulking so they cant reenter. They are just going in there to get out of the weather4. What are the different types of solar garden lights available in the market?If you are trying to just shine light on the whole garden there are spot light and flood lights available. If you want to accent the garden, hang lanterns or add any number of ornamental figurines. There are solar rocks that can be strategically placed to shine across your garden to. Use several to surround your work. Solar lighting is an excellent choice. Just make sure to get your panels in the sun and keep debris off of them.5. How do I keep rabbits from chewing electrical cords on my garden lights?Try the dog hair. Go to local salon and ask for hair from the floor6. How to kill wasps that've built a nest INSIDE my sealed solar garden lights?Try spraying it really well and quickly tie a plastic bag over the light so nothing can get out. They cannot breathe and will die7. Cool things to make in my yard?(: Bird feeders, humming bird feeders, ponds, decorative garden pots. Comfortable seating. Garden lights can be fun. They make these reflective twisty ties, that hunters use to mark trails so they can find their way around at night. Lost? Shine your light on that tree! They sell them in the sporting goods section of big stores. You could make little fairies out of them and hang them on plants that are illuminated at night. You could tell your cousin that fairies only come out at night and take him out to your peace garden at dark. I collect a lot of rocks and made a fairy park in a big garden pot. Made some miniature benches, a water fountain out of a geode and a white pebble pathway around the plants. If you do not have enough rocks, you could substitute various sizes of sticks. Tack them together to make a place for the fairies to chillax, when they visit at night. I hope you have fun with your fairy garden. Good luck! (:8. What is the best brand of solar powered garden lights? Where do i get them?Any brand is good. Just check for voltage (or wattage - I am not sure on this) - they come in different strength. It depends how bright you want the lights to be. Usually you can buy them in garden centres, or DIY stores with garden centre, but these places would usually stock cheep and cheerfull lights. If you want something prittier or desighner stuff (you know, you can get brick-shaped solar lights, then you just incorporate them in your garden path or wall design) then a lighting centre is the place to go. They have loads of them on ebay too, especially in ebay stores9. Would it be possible to hack solar garden lights into one big PV panel?a garden light uses one LED, or about 30mw of power. you would need 2000 of these to power just one 60 watt light bulb. not practical or cheap. you would be better served to get a single 60 watt panel. a clothes dryer uses a tremendous amount of power, you should hang the clothes out on a line to dry in the sunshine instead
Broke One of My Neighbors Outdoor Garden Lights, How Do I Cover It Up?
This is extremely funny (this is the asker posting) these "neighbors" have harassed my mom and have wrote a letter to the state over something very simple that they could've solved by simply asking us. **** these people I am not confessing anything to them1. What is good substitute for Gold Fish food? (outdoor garden pond with approx 50 fish 2-4 inches long)?ground up some dry cat food they love it. I go to a park alot that has a golf fish pond where you can buy food out of candy machine looking things and i was told it is pretty much just like cat food (so now i bring my own cat food in my purse so i do not have to pay a quarter for 10 little pieces) they love it . GOOD LUCK2. What specific time of year do i plant vegetables in my outdoor garden?Vegetable gardens are a lot of fun, but do require care and special preparations to have a nice one. This would not be enough space to go into detail, but visit the link below for all the info you need to have a nice and wonderful vegetable garden. Good luck!3. im getting married in a outdoor garden , what can i wear ?bride in formal dress white w light blue small beadsWear a seersucker suit. So chic for a small outdoor wedding. It's cotton so it will be lightweight and breathable, and it's not wrinkle-able. Ask the bride which color she prefers, they commonly come in blue and tan. Here's one from J. Crew bridal:4. can you use peat pots to plant in an outdoor garden?I agree, transferring young plants from the plastic tray pots to a peat pot is a waste of money and actually delays its growth. I have tried container gardening, but the results are disappointing with low yield. Your money is put to better use in buying inexpensive soil amendments to mix into the top soil. If you plant tomatoes and have clay soil, then I dig a hole about 15" in diameter and a foot and a half deep, put some granular plant food at the bottom and cover it with 2-3 inches of good soil. Then I bury the plant and start back-filling the hole with 50% native clay and 50% redwood soil conditioner/amendments (cheap, I bought a 3 cu.ft. bag for $6.99 at a local Home Depot Garden Center.) Initially the plants did not even come to the top of the hole, but I kept adding soil mix as they grew. 3 years ago I had a bumper crop of Beefstake tomatoes. One plant yielded 75 pounds of fruit, including the green ones I harvested at New Year's Eve (no frost to that date) and put in a box covered with newspaper to ripen them. Even those late harvest fruit tasted not much worse than the ones I've bought at Safeway for $2. 50 a pound.5. What herbs can i grow in my outdoor garden this summer in Canada?You grow medicinal plants for everyday ailments like Toothache Plant - toothache Peppermint Geranium - clearing of the sinus Garlic - aids in the removal of catarrh I recently got hold of a book "The natural way to better health and longer life" by Vaughan Bullivant - it is only a small booklet of 64 pages and I have found it to be a wealth of knowledge as I am setting myself up to do exactly the same as yourself - I simply do not believe in the medical institution and all their toxic chemical drugs.6. where do I buy moter for outdoor garden clock, the hands rust and the motor does not work anymore?hobby lobby or michails .hobby shops .or look up clock works online.hope this helps7. outdoor or garden wedding venues in dfw area 1200-1500 budget.?I would select the garden in a heartbeat. What number of humans are you inviting? Only some toilets is enough in my view, it can be not like every person will ought to go while..And in the event that they do...(which they wo not )..They are able to wait a minute or two till any one else finishes. The climate---just have a again up plan. If it rains, you could use the tent like you mentioned. Many humans do this. WE have become married in a backyard as good. The risk of rain certainly will not discontinue us. We each LOVE outside weddings. Our ceremony will handiest be 10 minutes lengthy. .With a few minutes of mingling before and after. Then we are off to a restaurant for the reception. If we would have the reception within the backyard--we might, but they do not enable it. The backyard the place we are having our ceremony--has NO toilets, NO dressing rooms. It sucks...But everybody (35 friends) knows about this forward of time...And considering we are best having the ceremony there it is just not too much obstacle. Our plan in case of rain? Light rain (sprinkle) we can still have the ceremony on the garden with the usage of umbrellas. Rough rain- we are relocating the ceremony to the restaurant. Fingers crossed for NO rain!!!!! In the event you like the garden you are considering--use it.

The last I heard was that the State was handing out IOU's. So by restricting businesses further by implementing green energy when there is not enough green energy sources to accomplish this and the environmentalists are stopping new green energy farms from being made in a timely manner is going to make California more viable? Does not make sense at allIf someone called "Philip" were to inherit the throne of the United Kingdom, would he be Philip I or II?Phillip I. Mary I husband was only created a king consort (something that has not been done since in the United Kingdom or its constituent realms probably because of how unpopular he was a King (consort)). Only a reigning king gets the numerals. Like in the case of William III who was actually created co sovereign with his wifeEli Manning or Philip Rivers?Eli Manning has 2 Super Bowl rings, game, set match & the winner is Eli Manningexplain how Philip 11 and Demosthenes are linked in history of classical Greece.?The main characteristic that links the two Greeks (Demosthenes and King Philip) is their attitude against the new term that had appeared in the 4th century; the tern of pan Hellenism. Let me explain. Demosthenes is from Athens, he is supporting the old system of the city state and of course he is fully supporting the Athenian hegemony over the Greek world. King Philip is the King of the ancient Greek kingdom of Macedon (the Greek Macedonia). He had build a powerful state and he is supporting the pan-Hellenism. Pan-Hellenism is a new idea that appeared and mainly supported by the orator Isocrates. It is the idea of a united Greece, a new alliance between all the Greek states. The new alliance will protect the Greeks and will design an attack against the enemy of Greece; the infamous Persian empire. Demosthenes is against such a concept. He only sees as far as his state borders. He attacks King Phillip constantly and with any event. He even reaches to the point to accuse King Philip of being non Greek; he calls him a Barbarian, the worst think you can say against a Greek. On the other hand King Philip is ruthless. He wants to make his kingdom the most powerful in Greece. He builds alliances and he is working to unite the Greek states. The winner is of course King Philip. He defeats Athens and Thebes and he creates the league of Corinth (The Greek alliance that will defeat the Persians) the essence of Pan Hellenism. He wo not live though to undertake the campaign. He will be murdered and he will be succeeded by his son. His son will destroy the Persian Empire. He will create a gigantic Greek empire and he will spread Greek culture and language all the way from Greece to India. History will record him as "Alexandros o Megas" Alexander the Great!how did john philip sousa die?his death cause was old age he was 78 when he died and at the time that was a high age so my logical guess is old ageDOOL: Mimi and Philip had a baby?Lauren introduced the infant. It became Mimi's egg and Phillip's sperm. It became meant to be Phillip's sperm and Belle's egg yet they have been given blended up with Shawn and Mimi's egg and sperm. Belle miscarried and Lauren became meant to terminate the being pregnant yet Bonnie payed Lauren to maintain the infant so as that Mimi and Phillip might have somewhat one at the same time so Bonnie could get her palms on Philips money for the duration of the infant and Mimi.
Lighting Suggestions for Weeping Mulberry?
Lighting Suggestions for Weeping Mulberry?
If you've never done any landscape lighting, I have to warn you. It is addictive. And it might be hard to find just one light. They usually come in sets for homeowners.The trick between professional lighting and homeowner lighting is this; you never ever want to see the light bulb or fixture itself. No blinding lights. Your beautiful tree should be uplit with a spot light or two. From this position a spot light set behind the patch of Hosta? would work to hide the spot light. But if you walk to the front door? or come around on that walkway from the side of your home? More than likely to be blinded. It gets tricky to place the lights just right. Black matt spot lights with recessed bulbs is all I would use with a moon light or two.Your landscape professionally lighted becomes alive at night. Very different than in the day light. Stunning. You should call some landscape companies to give you a bid. You want a low voltage system added to your electrical system. A box should have room to add more lighting because all the clients who started with...8 lights was the minimum, sold with an upgradeable transformer and there was a time where anyone with electrical skills was able to do this install. Not anymore. Find a landscape company that has its own licensed low voltage electrician.Within a month, we timed it, all clients wanted more lights. Another 8 or 12 or 18...the only thing people would see are landscape features; the sweep of branches and bark, shadows, back lit, down lit or up lit. Spotting a light on the side of your home will make a black shadow of a tree in front. Moon lighting worked best for a patio situation. Let's talk about security. Those motion sensored blinding lights? The bad guy could stand outside of the circle of light and be invisible. Landscape lighting is more subtle and the ambient light off your tree, your hedge is plenty to light pathways and see bad guys sneaking around. Add gravel and barberry shrubs under windows and bad guys won't even bother.There are, 'dorky', lighting packages at home depot. Cheap. It would get you started and playing with lighting and figuring out how to hide those spot lights. Those 'fixtures' should be matt black with recessed bulbs. Low voltage will have wiring buried 6 inches deep. Make sure they bury the wiring 6 inches deep, no less than 4. Don't get tempted (best to talk to wife first) purchasing shiny brass pagodas and fixtures that look like earrings. Absolutely no pathway flying saucers. Pathway lights are for airport run ways. Can't tell I am a little opinionated? Grins. I am telling you the difference between an investment that will add to the value of your home and one that will be lost, forgotten and worse, tripped over. But when you see the power of landscape lighting, you will be smitten. Can't hurt to get some free bids. And get ideas. It will be an investment but pales with the investment you've already made in your landscape that right now gets turned off every night. People would leave their homes in the dark to go to work and it would be dark by the time they drove into their garages. Only neighbors would get a chance to see the landscapes...I wonder if they have wireless lighting now? Forget solar. Unless the lights aren't the solar absorber themselves. Like having blinding light bulbs everywhere. You want to make your landscape the light fixture.• Related QuestionsDo the mountains around this Norwegian valley act like a giant battery?The scientific literature has almost entirely ignored this theoryThe episode (9:54) doesn't present the battery theory as conclusive fact.It is just a theory. They still need to work out how the theory could cause the lights to hang in the air. But for the time being, its the best theory they've got.There are two facets of this that can be checked:Is this a real theory real scientists take seriously?This perspective letter published in a scientific journal reviews 3 explanations for the phenomenon. The third explanation matches the one given in the episode. A perspective letter is more like an opinion piece than a in depth scientific investigation. They typically go through an abbreviated peer review.Physicists have suggested few models to account for the HL phenomena. One possible explanation attributes the phenomena to an incompletely understood combustion process in the air involving clouds of dust from the valley floor containing scandium (Hauge, 2007, 2010). Another hypothesis suggests that HL are formed by a cluster of macroscopic Coulomb crystals in a dusty plasma produced by the ionization of air and dust by alpha particles during radon decay in the atmosphere (Paiva and Taft, 2010). The valley's shape, microclimate or unique geology might also act as a giant battery that powers the lights (Monari, 2013). Until recently, none of the hypothesis/models described above seems to account for all the observations of HL and the very high energy source generating HL remains completely unknown.The Monar 2013 report presents the giant battery hypothesis, and presents some data that is consistent with the hypothesis. This data is far from conclusive and the report makes clear that this is just a hypothesis. It was not published in a scientific journal and I have no evidence that it went through peer review. It has gotten almost no scientific attention; According to google scholar, the perspective letter quoted earlier is the only scientific source that cites this report.I do not see any evidence that this theory is taken seriously by the wider scientific community.Is it "the best theory they've got"?The perspective paper mentioned two other theories. Hauge proposed that burning scandium causes the lights. Paiva and Taft proposed that it is caused by a dusty plasma. Hauge 2007, is a "preliminary report" that does not appear to be published in a scientific journal. It presents a little bit of evidence that supports the possibility that burning scandium dust is causing the lights. Although it has been cited by 8 other papers, none of them give it more than a cursory mention. Hauge 2010, was published in a peer reviewed journal and has been cited by two articles other than the perspective letter. I don't take either article seriously. One is short, doesn't really explain its methods or data, and is published in a probably predatory journal. The other explains that an alien "exo-civilization" built a "stealth extraterrestrial visitation probe" that is causing the lights.Paiva and Taft are two scientists who have published extensively about the Hessdalen lights. They have proposed several physical models for how the lights occur (2010,2012,2011,2012,2011). These models discuss dusty plasma, and charged particles emitted from rocks that fracture as they thaw. Most of them are published in peer reviewed scientific journals. Most of them have gotten at least 1 citation. The scientific community appears to take Paiva and Taft far more seriously than Monar or Hauge.This could be because their theory correctly explains the evidence, or it could be because they know how to write papers that will get accepted, or both. Although their work has more acceptance than the other two theories, that is a pretty low bar.Speculation about the showI personally have a good scientific background; for most scientific papers I can understand a decent amount of what is being discussed. Paiva and Taft's papers go right over my head. If the people creating the show looked at their work, they probably decided it was too complicated and arcane to try to explain to their viewers------Can we generate enough electricity to light up street lights by means of a dynamo being rotated by car wheels?Is it possible?Most likely yes.But:What challenges would one be facing for such an idea or design?These are what I foresee as the biggest hurdles you'd have to overcome.Hurdle 1: The laws of thermodynamics, in particular the first and second law. The first law of thermodynamics states that energy cannot be created or destroyed. There's a caveat here in that energy can be converted to and from mass using Einstein's famous equation, but there aren't any current automotive applications of Einstein's equation so we may as well assume energy and mass aren't converted to each other.So whatever energy it takes to run the lights will have to be put in by any vehicles driving on our fictional energy converter. This wouldn't be a problem except for the second law of thermodynamics which states that the entropy of the universe is at best not increasing. This leads to the concept of efficiency. Not all the energy of the gasoline your car burns goes towards "useful" work. Most of it is lost as heat. In fact so much heat is created by your engine that engines have cooling systems designed just to keep it from melting itself. Common gasoline engines have typical efficiencies of around 35%. This is before any efficiency losses created by wind resistance or efficiency losses of converting the car's motion through the converter to the street lights. Typical power plants which operate in a different fashion reach efficiencies of 50% or higher. This means we would end up wasting a lot more energy by trying to power lights off of cars instead of off the grid. Note that this hurdle applies to many different kinds of energy harvesting methods, not just Hurdle #2: The way automobiles work. Cars drive by transmitting power/torque to their wheels, getting them to spin. The wheel then spins and hopefully doesn't have significant slippage with respect to the ground, transmitting a friction force which moves your car forward. We say your car moves forward but there's no reason why we can't say the ground is moving backwards. If the ground is fixed from point A (source) to point B (destination) it really doesn't matter because either point B is getting closer to us or we're getting closer to point B.However, if the ground is rotating like a giant treadmill, the wheels can be spinning and we'd be moving with respect to a point on the treadmill, but the same reference point will also be moving away from point B. At best the car is moving faster towards point B than the reference point on the treadmill is moving away from it, at worst the reference point is moving faster away than we're moving towards it. Either way we're straining the engine more and likely arriving at our destination later, if at all.Hurdle #3: Reliability. A giant spinning dynamo is most likely not going to be reliable. This is because the system is being exposed weather, constant pounding of traffic, etc. The system would also be new and complex, the two worst enemies of reliability. Power plants and the grid used to transmit electricity are also quite complex, but these have had decades of refinement and testing to produce highly reliable systems.Hurdle #4: Cost. The electrical grid and power plants aren't there just to power street lights. They power our homes and businesses, too. They can also use a variety of energy sources such as wind, solar, coal, natural gas, nuclear, hydroelectric, etc. Many of these energy sources are significantly cheaper or easier/cheaper to harvest in large scale. In many cases these facilities already exist. In the other cases I would argue that powering street lights are the least of your worries.Conclusion: I'm sure it's possible someone could design a system to do what you described, but it would almost certainly be highly impractical, unreliable, and expensive
3 Best Solar Flood Lights You Need for 2021
Solar flood lights are one of the most invaluable investments you can make for the safety of your home. These lights are convenient and practical additions that will make everything from using a home security cam to unlocking your door at night a little bit easier. They can also help to keep the critters away from your prized tomatoes. A flood light is designed to flood an area with light. It's very straightforward. Flood lights are most important for outdoor applications. Inside, you have your walls, mirrors, and surfaces of your furniture to help bounce light around to fill the space. One bulb can take you a long way in a small room. Outside, you do not have that luxury. It's a vast expanse, and without a well defined space to contain a light, it sort of leaks out everywhere. A normal light outside wo not go very far. Since a flood light is designed to beam a high concentration of light directly out into a wide area, they will do a better job at illuminating a vast expanse. Flood lights are used to illuminate outdoor concerts and sporting events at night. These flood lights are a lot more powerful than the kind you would need to illuminate your home, since your back porch is substantially smaller than a football stadium. Flood lights for home use are compact, easy to use and install, and relatively inexpensive. Boundery's LumiGuard Pro is an ultra-bright 270 degree motion sensing floodlight. It's the perfect one size fits all solution for some security and safe illumination. It easily installs on your front porch or by your back door, giving you enough light to safely enter and exit without tripping over the doormat or trying every key on the ring. The LumiGuard Pro XL was designed with home security in mind. Our biggest and brightest floodlight can be used to illuminate very large areas, making it helpful for homeowners with a lot of property. It's designed to detect motion from up to 25 feet away, neutralizing threats the moment they approach. The Original LumiGuard is a compact and powerful solar floodlight that installs in minutes. It's the perfect replacement for battery powered LED flood lights, providing substantially more life without the hassle and waste of constantly replacing batteries. Why Do I Need a Flood Light? There are a lot of excellent reasons to add a few flood lights to the front and back of your house. You can position them wherever you need them to make your life a little easier at night. After work, you stop off to have dinner with a friend and run some errands. You make a last minute trip to the grocery store so you can meal prep some healthy meals for the upcoming week. Before you know it, you are getting home at 8 PM. The porch light is not on. You now have the troublesome task of figuring out how to get your groceries to the door that you cannot see to unlock. It's a huge pain, and you are kicking yourself for forgetting to leave a light on. A motion activated flood light solves that problem. As you approach the flood light, it will turn on. You can hold your groceries in one hand and unlock the door with the other because it's easy to see what you are doing. Need to run back out to the car to grab that 12 pack of seltzer? The light will kick back on. If you are having people over for a night time gathering, you probably have a well lit gazebo or porch area. But what happens when someone needs to walk to their car or around the house? They are probably unfamiliar with where they are going, and you do not want them to trip and fall. Solar flood lights and Boundery's Solar LED Stair Lights can make it safe for people wandering around in the dark. People with bad intentions do not want to be spotted. If anyone were casing your house to vandalize or burglarize it, they certainly do not want to do so with a bright spotlight shining directly at them. Mischievous teenagers are programmed to run the moment a light kicks on. It will give them the sense that someone saw them, or that someone could easily see them if they noticed the light kicked on and looked out the window. Strategically placing motion sensor lights near security cameras will help them capture clearer footage. If your camera's night vision leaves much to be desired, keep it in its normal mode and back it up with some solar flood lights. If you live in a quiet area or have a small patch of woods behind your home, you probably love the view. What you do not love is the curious deer and raccoons that want to see what kinds of plants are growing on your property. Rabbits are just as interested in finding snacks at dusk as they are at dawn. If you are growing fragrant herbs, fruits, or vegetables in your backyard, put up a solar light. Any curious animals looking to steal a bite will be scared off when the light kicks on. Motion sensor lights work by detecting infrared waves. People, animals, and cars emit heat. This heat energy can be seen by a motion detector light, especially when it's moving. The sensor picks up on the heat signature that passes before it and, in response, turns on the light. Motion sensing lights can sometimes be triggered by things like foliage aggressively blowing in the wind. If this is a dealbreaker for you, just trim the bushes. You can also adjust the placement of your lights to avoid pointing them directly at greenery. Why Are Solar Lights Better Than Electric Lights? Solar lights are better than electric lights for countless reasons. The most obvious reason is that they do not ever cost you anything to run. They use the light from the sun to charge an internal battery. When the sun goes down, solar flood lights know that it's dark and will automatically begin to work.

You do not need to run wires or extension cords or create hazards to power your solar lights. Anyone can install them with simple instructions and basic tools. How Many Solar Flood Lights Do I Need? The amount of solar flood lights you need depends on what you are trying to achieve. You may only want two: one for the front door, and one for the back door. If you tend to take the trash out at night, it may help to strategically place one by the cans. If you are using them for home security, you will want them near every entrance and exit of your home. You might want to place them near your security cameras or, as a precaution, near any areas of your home that get particularly dark at night. If you entertain on your property, you might want to place them in a way that they will illuminate the way to the nearest entrance of your home. It's polite to help people find the bathroom during a bonfire or late night whiskey tasting. Solar flood lights can be affixed to your exterior walls with screws. They have a place for those screws to go in the form of a built-in mount. It's usually as simple as using the right drill with the right bit to prepare the wall and affixing the light. It is not much different from hanging a mirror or a picture frame. Your solar flood light will come with detailed instructions. Every home can do with a few solar powered LED flood lights. They are a one-time investment for a lifetime of convenience, safety, and peace of mind.

Solar powered LED lights are ready to go right out of the box, and even the laziest DIYer can have them up and ready in time to eat a sandwich and take a nap.

How to Change the Outside Look of a Metal ShedConsult with the paint store for advice on suitable paints for your metal shed. Choose paint colors that suit your garden decor. Generally, browns and greens help the shed "fade" into the surrounding garden, shrubs and trees. Paint the shed the same color as your house to tie the two buildings together. Hide unsightly items such as firewood or a lumber pile behind the shed, or move it to another location. A common homeowner's dilemma is the metal shed in the back yard. It is a practical, utilitarian structure that allows you to store all the garden tools, the lawn mower and perhaps a bicycle or two. Unfortunately, a basic metal shed is just plain ugly. An industrious homeowner, however, can transform that ugly blotch in the landscape into a decorative element in the garden in just one weekend. With the addition of paint, planters, trellises, plants and decorative elements such as faux windows, new doors and solar lights, an ugly metal shed becomes a statement of garden decor ingenuity.6. i purchased used walkway type solar lights but they won't light. what should i do?Get new ones . They are so cheap7. you know those solar lights, the sun shines on them by day and they light by night.?The oceans are giant heat capacitors - they soak up heat during the summer and gradually radiate it away. That's why, in the Northern Hemisphere at least, the weather continues to get warmer after midsummer and is coldest just before Spring rather than at midwinter. All you need is a giant tank of water in your conservatory, that will do it. Or, if you focus the heat into a tank of water and let it boil then you could use the steam to make electricity and then store it in batteries until the winter.8. How long does it take for new solar lights to work?I bought my first set of stainless steel garden lights about 2 months ago.Fortunately for me it had instructions. The solar lights have to fully charged on the first day - about 8 hours of sun. Make sure you place them where they will get the maximum amount of sunlight. My solar lights have been on every night so far even on cloudy days (they do not light as long in the night on cloudy days as they do not get fully charged, but they do light). If you did all those things, then I think you need a refund or exchange on your lights. Good luck!.9.
