Be Careful! There Are Skills to Purchase Products From Solar Street Lamp Manufacturers!
Be Careful! There Are Skills to Purchase Products From Solar Street Lamp Manufacturers!
No matter where we are, we can see the shadow of solar street lamps at night or during the day. Why can solar street lamps be so widely used in people's life? That is due to the use of such street lamps, which can save energy. So, how to select solar street lamp manufacturers? Next, Xiaobian will share the skills with you.1. Choose a regular manufacturerIn fact, no matter what type of objects are produced, regular manufacturers are always the first choice for many people. Why? Very simple, because the things produced by regular manufacturers can be said to meet the national standards, and there are few potential safety problems. After all, they all rely on word-of-mouth to expand their own enterprises, otherwise the brand will not be known by people and become the reason for people to choose.Therefore, when choosing solar street lamp manufacturers, we must choose regular manufacturers. Only regular manufacturers will be really responsible for the orders bought by consumers.2. Select manufacturers with after-sales serviceWhether there is after-sales service is an important factor in selecting manufacturers. Because after any product is bought by consumers, consumers will use it. When they find that there are problems with the product, they can't contact the merchant. How desperate should they be as consumers?Therefore, in order to avoid finding that the manufacturer cannot be contacted due to quality problems after purchasing solar street lamps, we must select the solar street lamp manufacturer with after-sales service.After reading the above two points, I wonder if you have a new view on the skills of manufacturers of solar street lamps? No matter what you think, I hope you can use these two skills in reality.
Where Can I Find a Lighted Palm Tree?
I agree with going to Michael's. I got mine there a few years back and it is over 5' tall. I did not use solar lights because I wanted a showier look. I wrapped green Christmas lights in the palms and then used a rope light wrapped around the trunk to fit. It does not use much electricity because of the low voltage and you can put it on a timer for the amount of time you want. Wait until they have a 40% off coupon and they will be quite affordable1. My solar lights are probably 3 yrs. old.?HD and Lowe's will probably have them, batteries for sure, bulbs maybe. If they are good quality metal, then try to fix them. If they are plastic I would junk them and start over.2. anyvone know about outdoor solar lights?They have what is called a Photoelectric Eye, which senses electromagnetic radiation TRANSLATION: LIGHT! When the Eye sees no light, then it turns on3. Amazon is selling these flickering flame solar lights for £30.99Solar lights are one way to instantly transform an outdoor space. Affordable and low-maintenance but highly effective, you just charge them in the sun during the day to create a stunning light display in the evening. The StillCool Solar Flickering Dancing Flame Lights are the ultimate cosy lighting for autumn. Not only are they perfect for creating a warm ambience in your garden, but they wo not affect your electricity bills either. Candles are perfect for creating a cosy atmosphere, particularly in the autumn, but they are not the most practical for outdoor lighting. If you want to recreate that warm glow, the StillCool Solar Flickering Dancing Flame Lights are the next best thing. Safe and realistic, the lights have proved to be a big hit with Amazon shoppers. 'Fantastic value for money' wrote one delighted shopper 'The warm candle-like glow and imagery they give out are second to none! 'They are extremely realistic and give an excellent ambience to our rockery and water feature that they surround. I would 100% recommend these fantastic lights.' Another shopper wrote: 'These lights are amazing. My husband was unsure on solar lights to begin with, but he absolutely loves these lights. 'We have had lots of compliments from our neighbours about them. They are beautiful when they come on and look like candles burning away with the flicker.' To use, charge the solar lights in direct sunlight (it should take up to eight hours) then the solar panel will convert the sunlight into electrical energy, ready for ten hours of battery charge. As the sunlight is not as strong in the autumn and winter, you should get at least five hours in after fully charged. While shoppers say these lights create a 'warm, cosy light', it's worth noting that they are not super bright, so if you are looking for powerful lights, then you may need electric ones. One reviewer wrote: 'These are really beautiful in the garden at night. The amount of light they put out is minimal, but as a decorative light, they are perfect. The flicker effect is very good & they are much bigger than I expected.' With no cords or wiring needed, you can place the StillCool Solar Lights wherever you like. Use them the line your pathway, place them at the entrance to your garden or put them in the flower beds to create a lovely glow at night. Another customer raved: 'They look fantastic at night... They flicker very convincingly and look far more substantial than the usual filling station offerings. They are not cheap, but they are worth the money.'

SOLAR STREET LIGHT ARUDRA SOLUTION
A solar street Light Luminaire is a lamp technology that utilizes solar cell to obtain electrical energy during the daylight hour by solar radiation and then use the electrical energy to provide light at night. Semi integrated lamp tries to overcome complicated installation and expensive price of normally solar street lamp. Semi-integrated solar street lamp only integrated solar cell, controller, and battery, while lamp is separated using cable. This configuration makes semi-integrated lamp cheaper and easier for installation that is suitable for rural area. Therefore, in this paper we develop semi-integrated type of solar street lamp. The illumination of semi-integrated lamp was measured using lux meter. The power of the lamp was calculated to meet the energy needs for 12 hours. The results show that the semi-integrated solar street lamp with low power LED 2W has been successfully developed. The solar lamp can be automatically turned on for around 12 hours, from 5:50 PM to 5:30 AM (UTC5:30). The illumination average of the lamp is 17.42 lux with 6.97 lux deviation. The measurement result of illumination shows that the solar street lamp has maximum distance of more than 140 cm with 230 cm high of lamp. Street lamp is a necessary part of every part of the street, with a primary function is to provide comfort to the driver and pedestrian. Street lamp also has a security function that is to prevent accidents and criminality. On the other hand, from environmental and economical perspectives, solar street lamp is better than the traditional street lamp, since the traditional technology uses far more energy during its operational life [1], [2].Solar street lamp is a lamp that utilizes solar cell to obtain electrical energy during the daylight hour by solar radiation and then stored in the battery [3], [4]. At night, the energy saved in the battery is used to provide light on the street. Generally, there are two types of solar street lamps: (a) unintegrated lamp; (b) fully-integrated lamp, as shown in Figure 1. Unintegrated lamp is a lamp which are each component, i.e. lamp, solar cell, controller, and battery, separate from each other, as shown in Figure 1(a). However, the lack of this type of solar street lamp is in need of a complicated installation. Different from un-integrated lamp, fully-integrated lamp has integrated all the components of each lamp, as shown in Figure 1(b). The fully integrated lamp causes easier installation, although the component price of this type is expensive [5].Semi-integrated lamp (Figure 1c) tries to overcome both problems that is expensive and complicated installation. Semi-integrated solar street lamp only integrated solar cell, controller, and battery, while lamp is separated using cable. This configuration makes semi integrated lamp cheaper and easier for installation that is suitable for rural area. Therefore, in this paper we develop new type solar street lamp, namely semi-integrated type of solar street lamp. For the measurement of the solar street lamp, the illumination of lamp was measured using lux meter. Furthermore, the power of solar street lamp was calculated to meet the energy needs of the lamp for 12 hours.if solar cells were 100% efficient?Let's jump in. M square meters * (1000 watts/square meter if efficient) * 20% * 6/24 of the day = 1 kilowatt * (1000 watts/kilowatt) That's a lot like M * 1/5 * 1/4 = 1. I would say M is 20. ;)Assuming we found a renewable source of antimatter, would we use annihilation energy indirectly and inefficiently (via water heating), or could we directly harness pure energy, such as emitted photons through something like solar cells?The annihilation would be through particle- antiparticle pairs which would produces pairs of gamma photons. I dont think any attempt has been made to make anything like the equivalent of PV cells for gamma radiation.Using it as a source of thermal energy is ok but the gamma is very penetrating and it may be difficult to absorb the highest energy photons from proton or neutron annihilation. The source of anti mattewr is quite tricky, if a source existed, it would not hang around until you were ready to use it/ you cpoould not piupe it to the preferred location. How much electricity can our best solar cells generate? Can it be stored?the mass produced solar cells are only with 17% efficiency, that means it's convert 17% of the solar energy into electricity. for the other question: the electricity generated by solar cells could be stored in a battery system, it's could be lead acid battery or any other kind batteries.
How Do Solar Lights Work?
Solar lights collect energy using a small solar panel, also called a photovoltaic cell or a solar cell. These cells are made of a semi-conductor, which is usually silicon. Semi-conductors are materials which are sub-metallic, and under certain conditions, will act like a metal and allow current to flow. When light of certain wavelengths strikes the electrons around an atom in a solar cell, the electron becomes excited and gains enough energy to break away from the atom and "jump into the conduction band". When this happens, it leave a "hole" which is filled by another electron, but this electron had to come from somewhere right? This movement of electrons produces a current. In those solar powered garden lights, this current used to charge a battery which will power the light during the night. The light also contains a sensor which will sense when the sun is no longer up, and turn the light on.1. Solar Lights not turning on even with new batteries, cleaned them all, and have plenty of sun.?1. Do you have the right type of battery? Most of the ones that I have run on nicad rechargeable. 2.Check the battery connections, the tend to corrode because they are outside. 3. Test with a charged battery to see if light comes on. 4. Most newer solar lights are LED's because they are energy efficient. If they are not LE D's check the bulbs2. How do you make solar lights at home?Do you mean those garden lights? The electronics are pretty simple. A solar cell, rechargeable battery, a custom chip, inductor, abd of course the LED. Add in a housing and you are all set.The best way to obtain this stuff is to just buy one at a Dollar Store as you will pay much more for the parts then they do.3. How To Make Solar Lights Last Longer?To light up a grave site all night long you need both sufficient battery storage and sun and solar panel surface watts. Here are a few solar spot lights I would suggest:4. 10 Best Solar Lanterns for Camping & Home in 2021Solar Lanterns idea to power your life might seem farfetched and daunting at first glance. Nonetheless, it does not have to feel like that. Going for solar-powered lanterns can narrow your choices down, and you will be the biggest achievement when it comes to saving you a lot of electricity bill menace. Opting for Solar Lanterns is undoubtedly a lifesaver more so when we are living in times of outrageous electric bills. However, do these solar lanterns work? Are they up to par with the typical electric bulbs ordinary in most homes? Are you staying in a shady compound without the rays of the sun? Here are the scoop and snoop on what these new craze solar-powered lantern lights are all about. A solar Lantern also sometimes referred to as solar light or solar lamp is a lighting component that comes with a solar panel, charge controller, battery, an inverter, and a LED lamp. The Solar Lantern makes use of the electricity emitted from the batteries which have been charged by the solar panel. Related: The Best Hanging Solar Lights for your house garden It is becoming an alternative to daily household light sources like kerosene lamps, candles, and electric bulbs. Being a renewable source of energy, solar energy has been deemed cheaper and environmentally savvy as compared to other power sources. Harnessing the sun's power was deemed impossible some centuries ago, and it sounded like a mad scientist idea. However, it is a different scenario today with rooftops dangling with solar panels, and the street lighting has not been left out too in this solar raze. Has it ever pondered in your mind how solar lantern transform the rays of the sun into electric power and still lights up your compound even when the sun is set? Could this be magic? It is science! Solar Lantern uses a photovoltaic effect mechanism to work. The solar cell or the photovoltaic is a very crucial component of the solar lantern. Direct current (DC) is mined from the sun through the solar cell. The solar cells are usually evident in the astral light; they are a dark panel. Each solar cell is coated with numerous crystalline silicon layers and chemicals which bring about positive and negative electron charges. When sunlight goes through a solar cell, the negative electrons react with the sun rays hence being sent to the positive electrical charged areas. The electrical streams are transferred as direct current by the positive charges using wires connected through the solar panel directly to a battery for storage purposes. As sunlight is transformed into electricity, the solar battery keeps charging. As evening approaches, the electric conversion by the solar cell is halted by the dim and weak sunlight. The light photoreceptor automatically turns the lights on when it detects darkness. This process is monotonous as the days keep going and the nights come it is a repeat of the entire process. When discussing the types of solar lantern lights, they are usually put into two types - camping and decorative. Fluorescent and LED are also a classification model. Some even come as strings or jars. The beautiful decorative solar lanterns can be used interchangeably from decorating parties to magnifying the ambiance in our backyards. Others can be used as a path or border marks. Example of these lanterns includes Moonrays 91165 Solar Powered White Washed Metal Lantern Amber LED LightMorrocan, Solar Powered LED Garden Flameless Candle Lantern, Falove Vintage Waterproof Solar Powered Lantern, and many others. If using solar lanterns has ever crossed your mind, then the listed below advantages should hasten your lighting choices. It is evident that solar energy comes free from the sun which makes it a cheaper alternative Very simple to install you wo not need technical help from third-party installation companies. When it comes to maintenance costs, it is close to zero and very cheap. Most of these lanterns come with automatic on and off sensors that will turn on and off without your intervention. How cool! The attractive designs blend so well with modern construction techniques hence adding the beauty and ambiance to your yard, home and streets. It will be easy to get what fits your needs as there are a lot of models to go for. When it comes to cutting down on power bills and protect the environment is by opting for solar energy. These lights work just like the usual electric lighting system and can be used to light up our streets, backyards, homes and even carry along when going camping. Solar outdoor lanterns can also be used to beautify event venues, improving home security and adding color and ambiance to your house.
How to Set the Distance Between Solar Street Light Pole?
Many customers have many questions about how to set the installation distance of solar street light pole. In fact, this problem is not much troubled. It can be solved purely based on experience, and there is no absolute scientific basis for how far the distance must be.From the user's experience level, of course the brighter the light source and the brighter the distance between each light source at night, but from the perspective of investors, of course, the fewer the number of solar street light pole installed, the less investment they can. Spending money on other investments is the best job we need to do as a solar street light manufacturer if we balance these two ends. For the installation of solar street light pole, we have a density reference, we cannot be too close, or we can see the ghost points from a distance, and it does not make any sense. It also causes a waste of resources, which is too far away. Blind spots of lighting, where there is no continuity of light is also a failed approach, so experience is very important. As a simple example, the distance between a 6meters height 30-watt solar street light pole and one of the other is suitable for 20-25 meters. Don't ask why this is experience. The lighting effect of this arrangement will satisfy everyone. The seamless lighting range and the high brightness of the light source are just right, and the interval is neither long nor short. This is the rationality of the lighting arrangement.The above is just a simple example, do other wattages or heights also use this as a standard? Solar pole lights close to 6 meters and 30 watts can be changed on this basis. If the difference is large, they can be adjusted in equal proportions or communicate directly with solar street light manufacturers. Mas Solar will give you a satisfactory answer.·RELATED QUESTIONWhat's the meaning of Sia's Chandelier song?Before Chandelier, Sia was a singer with mediocre success.She was really struggling to push her career when she lost her partner to an accident.

Solar Street Light for the Home and Business
The introduction of solar street lightSolar street lights are a great solution for urban areas, as they can replace the need for electricity.The introduction of solar street light is not only to meet the demand of the users but also to help people save money on their energy bills. The introduction will be done through various ways, like a series of solar street lights around the city and along our highways. It will also be implemented by setting up mechanism like "Solar Street Lights" or "Digital Citizen's Grid".Tips for solar street lightSome cities have already started installing solar street lights to put the solar power on the streets. However, they are still far away from being fully functional. As a result, they often need some manual work done by a maintenance man.How to use solar street light?How does a solar street light work?The specifications of solar street lightSolar street light is a type of lighting system that uses solar energy to produce light. The technology has been around for decades and we can rely on it to provide electricity for our homes, offices and even the streets. However, these solar street lights do not have a long lifespan.

Go Carbon Neutral on Outdoor Garden Lights
How to get carbon neutral lighting in your garden.Installing lights outdoors can be a tricky business and if you want to be carbon neutral then the best option is to choose outdoor solar lighting.... How to get carbon neutral lighting in your garden. Installing lights outdoors can be a tricky business and if you want to be carbon neutral then the best option is to choose outdoor solar lighting. There are many different types of solar lights on the market. The older types used Nicad chemistry to power the cells, newer models now run on NiMH cells. Solar lights powered on NiMH will not suffer the memory effect of the old Nicad and will last for over 1,000 charges without any loss of power. By carefully placing each light in dark corners and making sure daylight will reach the solar panel they will continue to charge even on dull days. If you are lucky to have a south facing garden then positioning the solar lights will be no problem. For gardens facing north or if you have tall trees and shrubs make a map of the plot and work out the best angle for the solar panels. Ground solar lights often have spikes which can be pushed into the ground at an angle to face the sun. Garden items will weather, to avoid replacing worn , cracked or rusty lights the best option is stainless steelm solar lights. These will stay clean and bright for many years and just need a yearly clean to keep the solar panels clear. To replace the cells just remove the solar panels to access the cells. Most run on AA type cells and are widely available from hardware stores or visit urbanlights.co.uk
How to Fix Solar Lights? Guide to Troubleshooting/Disassembly
Girl power! India's 'solar gal pals' light up rural homesALWAR, India (Thomson Reuters Foundation) - Buffalo trampled over it? Rain drenched it? Child dropped it? No problem! This solar flashlight can endure it all, said Bassi in a pitch to her neighbours in rural India to convince them to power their homes with clean energy instead of polluting fuels.Bassi is one of 2,500 "Solar Sahelis", or solar women friends, who fan out to different villages and persuade families to use solar energy in the western desert state of Rajasthan, which sees about 300 days of sunshine every year.With unreliable electricity and hours-long power cuts every day, many rural families in Rajasthan are often forced to rely on candles, kerosene oil lanterns or burning wood, which emit soot and noxious fumes.They not only can lead to premature death due to disease, but can also cause fire accidents and burn injuries.That is why solar is the way to go, 26-year-old Bassi, who goes by one name, told the Thomson Reuters Foundation in her village of Moonpur, about 130 km (80 miles) from state capital Jaipur, where buffalos and cows wander the dusty streets."They just makes more sense - affordable, long-lasting, durable and safe," said Bassi, who has sold up to 32 solar flashlights since becoming a Solar Saheli last year.Even then, Bassi said it can be a challenge to win over villagers who are usually wary of the initial higher costs and distrust solar products due to experience with some flimsy products from China.The most popular product, the "Solar Rakshak", or solar protector, flashlight costs between $10 and $20, while a regular battery-run one would be about $5.But once doubts are cleared, almost every customer is satisfied, said Bassi.Kamlesh Devi, a mother of two, bought the Solar Rakshak in June after Bassi assured her that it would save her frequent trips to the market for new batteries and lights, and help her children study without any irritation to their eyes."I used to buy flashlights for 300-400 rupees (about $5) that would malfunction within six months. Sometimes it would fall here or there. The batteries would die quickly. But this is a great thing," said Devi, her head veiled with her sari."The kids are studying well. Until 10, 11 at night, even if there is no electricity, they study very comfortably," she said.Jaipur-based Frontier Markets, the social enterprise behind the project, said its mission is to provide over 10 million clean energy products to 30 million households in India by 2020.But the project is not just about going green.It also aims to empower women in the male-dominated, conservative state, where child marriage is rife and girls are routinely denied an education and live a life largely confined to home.Bassi's life was headed there too. Forced to marry at 17, she was regularly beaten up by her husband before she ran away and moved back in with her parents.When she insisted on studying further, her elders refused, saying she brought shame to the family.That is when Frontier Markets found Bassi in a self-help group for women and trained her to spread awareness and sell solar lights in remote areas of Rajasthan."If not for this... I would have just stayed at home, tended the buffalos and done household work. That is all I would have been good for," said Bassi.Having never ventured out much or spoken in public before, Bassi said she was jittery at first, unsure whether she would be taken seriously or be able to sell anything."But now I feel like I have no fear," said Bassi, who unlike most rural women travels miles out of her village, interacts with men and earns an income - up to 2,000 rupees ($28) every month."Women are not weaker than men. At least I do not have to depend on anybody for money," she said."On days when I feel like buying something or wearing something new, then I know I have my own money and I can do whatever I want."The Solar Sahelis have collectively earned more than $2.5 million by lighting over 500,000 homes, according to Frontier Markets."In order to drive true women empowerment, they need to be economically secure. The second you put money into women's hands, everything changes," said Ajaita Shah, the 34-year-old founder of Frontier Markets.The rise in family incomes has made the Sahelis confident and more involved in household decisions, she said."The fire we saw in some of these women, it is like they were finally recognising that their voice has value," said Shah.Repeated studies show that when women control the family's finances, they invest more in their children's education, healthcare, businesses and communities, which can be a step out of poverty.While such programmes seek to boost women's rights, experts warn they can backfire at times as they upset traditional norms and spark conflict, especially in conservative pockets of India.Rajasthan is known as much for its beautiful palaces, camel-back desert safaris and colourful apparel as for its age-old customs like purdah, or veiling, of women.It is home to some of India's poorest villages where politically powerful councils, mostly comprising elderly men, have an iron grip over social and moral life.Women are often expected to conform to established gender roles such as being the main caregivers who look after the home and children despite modern, urbanising times, experts say.That is why it is essential to sensitise villagers about changing dynamics, said Shashank Bibhu of CARE India, a charity that works for women from poor, marginalised communities."Otherwise, in the past, we have seen that it has led to domestic violence," he said.He urged organisations to counsel communities about gender equality and promote supportive men as role models who share household responsibilities.For Radha Devi, working as a Solar Saheli has not been very easy due to the lack of help from the men in her family."I struggle to balance household work and this work," said the 37-year-old, who became a Saheli last year."Men do not have to worry about household work ... so they progress in life. But women have to think a lot about how they will take out time for their jobs," she said.Still, that does not dim her hopes of making it big one day."The plan is to open up my own store ... and make a name for myself," she said, wearing a bright yellow Solar Sahelis vest."Success takes time. One should not lose confidence."
Outdoor Solar Lights Are Not Working?
yes first you checked that whether you put batteries correctly or not1. solar storms pose a threat to electric grid?The massive magnetic flux acting on a wire induces a current, which, if not shielded against, can cause considerable damage. I am informed that a huge solar storm in the 1800s, before we had an electricity grid, caused sparks to be emitted from circuits which were not even connected, giving electrical shocks to telegraph operators. If this happened to nuclear reactors, it would stop the pumps cooling them, causing disasters on the scale of Fukushima no. 4. solar storms news and articles - Natural News Mar 20, 2012 ... solar storms news and articles. ... Solar storms could bring down modern civilization.2. Why is solar insolation so important?'Solar insolation' is redundant b/c the word 'insolation' is derived from the phrase 'INcoming SOLA radiaTION.' The sun's energy drives the weather...the ocean currents...flora...and fauna. Insolation is so important b/c without it... life on this planet...as we know it...would not exist.3. Invalidation of the Solar Nebula Theory?No, it does not , but it does suggest something that had not previously been considered: it's possible for Jovian planets to migrate inwards from where they were originally formed4. what are the different types of solar power?i do not know i did not even know there were different types of solar. or are you just playing with me?5. How can I calculate the rate of power consumption of a solar car along a known route with changes in elevation?Not sure if this approach is in the format you need, but it might help. The work required to go uphill by a height $y$ is$$W=mgy$$where $m$ is mass and $g$ is gravitational acceleration. Assuming mass and gravity are constant, we can differentiate this equation with respect to time to get:$$dotW=mg fracdydt$$we can also use the chain rule to rewrite it as$$dotW=mg fracdydx fracdxdt$$in which $x$ is the horizontal distance traveled. Then, $fracdxdt$ is just velocity, so the equation reduces to $$dotW=mgv fracdydx$$You already have the data for $fracdydx$, so you can factor out the velocity and insert this equation into your first equation for total power consumption:$$P_w = (F_air F_roll mg fracdydx ) cdot v $$6. Is A Solar Dyson Sphere Habitable?I am not a big fan of the spheres and I have no solution for the gravity issue, but I will make a fake answer to make some points about the energy issues that are really bit too long to be comments.Can be anything you want within upper and lower bounds set by engineering and the total energy of the star. There are lots more variables than trivial models assume since the structure of the sphere is realistically more complex. There is no one-to-one connection to the temperature of the inner shell. You can use insulation to make the outer shell cooler than the inner shell. You can use heat pumps powered by photoelectrics to make it hotter. Or more robustly simply connect it to hot areas of the inner shell. Yes, I said hot areas, there is no reason why areas of the inner shell must all have the same temperature. You can give different areas different albedo. Or simply link different areas on the inner surface to areas of variable size on the outer surface. If areas A and B on the inner surface have the same area but the outer shell radiator A is connected to has ten times the area of the radiator B is connected to, A will be cooler. The sphere is not, cannot be, made from homogeneous mass, it has structure. Since the temperatures of inner and outer shell are not directly linked, you can use insulation to make the sphere habitable at a distance higher than usual or cooling to make it habitable closer. So you do not need to worry about what the insolation or habitability of a planet at that radius would be. For example if the sphere is larger, you can replace parts of the inner surface with mirrors reflecting light to the inhabited parts. If smaller you might give the inhabited parts higher albedo, so that radiation is reflected to the uninhabited parts.There is no known way to get a comfortable gravity to the inner (or outer) surface. Nor should there be. a Dyson sphere is not a habitat, it is an energy collector. You should build your spin gravity habitats separately and just use the power collected by the sphere to power them. Or just use planets. Technology needed for a Dyson sphere should allow building planets. And the mass needed would allow building lots of them. Just because having six planets on the same orbit is not stable, does not mean you can not make it so. It would be easier than building a Dyson sphere. And making the planets habitable would be much easier. Like I said in the beginning this was not really an attempt to give an answer. Just some comments too long to fit into actual comments. You should not expect any of what I said to be true or accurate. Just some food for thought.
How Can I Brighten Dim Solar Lights?
How Can I Brighten Dim Solar Lights?
Hi, Do not forget to clean the small solar panel from time to time. If you do not the batteries will not recharge properly.1. Can solar lights can be used at night on airport runways?Yes, with a batt. for nite,But i wouldnt trust a battery for too long. maybe for dead people?!2. how long does it take for batteries to charge in solar lights?3 = 4 hourss3. ok, let me make it clearer, what light can you use to charge solar lights? Besides the sun.?The point of solar cells is that sunlight is free. If you charge your batteries with any other light source, you will get less back than what you put in. It would make better sense to use the original light source when you need the light. Anyway, solar cells will charge your batteries on a cloudy day---just not as fast as a sunny day.4. How do you recharge the rechargeable batteries in solar lights?It is possible to do this but you have to see the time controlling5. Do all solar lights take time before they start to light?I have small solar lights in my front yard. They took about a day of FULL sun light (not overcast outside) to light up. I kept thinking they were broken. They would not stay lit all night either. They still do not . So they do take time.6. anyvone know about outdoor solar lights?They have what is called a Photoelectric Eye, which senses electromagnetic radiation TRANSLATION: LIGHT! When the Eye sees no light, then it turns on7. Outdoor solar lights not very bright why?Usually they only have one LED bulb in them, one LED bulb is not going to give off much light, and it depends on the reflector inside as well, more LEDs more light, and also there are different LEDs that give off different strengths of light8. how do solar lights work?The panel on top of light absorbs solar energy and convert it into power which will be instored in batteris during daytime; at night, the battery will charge the LED light for work9. Why has one of my solar lights flipped to come on in daytime?there is a little photo electric eye probably on the top - make sure it is not covered with dirt or anything else... might look like a small round hole or a little domed button... check the lights that work to find it and see if something is different on the 'bad' light. If you can not find anything, the light sensor (electric eye) may have shorted out10. 10 ways to brighten up your garden in winterWith a little imagination and creativity, it's easy to add interest to your garden in the winter months. For the greatest impact, concentrate efforts on a few key areas that you see on a daily basis. These might include beds and pots close to the house, as well as the front garden, which you walk through every day. We've rounded up some of the best ideas to inspire you. Many require little effort and some are great value for money too. So, whether you step outside or look from your window, embrace winter and enjoy your garden at every opportunity. Brighten it up with simple lighting In winter, we often come home in the dark and miss seeing the garden altogether. Outdoor lighting can bring it back into play and transform the view from windows that would otherwise be dark, reflective panes. Try a few tea lights in clear jam jars to add seasonal twinkle for special occasions and solar lights to provide a few hours of decorative light. Fairy lights are fun draped in a tree and there's a wide range of lighting kits on offer that are quick and easy to install. Be sure to switch lighting off before going to bed, to minimise disruption to wildlife. Even just one piece of evergreen topiary will add interest to a pot or bed and hold an area together in winter. Formal shapes such as balls, pyramids and cubes work well, but if you like a more relaxed style, then the trend for looser 'cloud-pruned' and organic topiary shapes may suit you. Box and yew are traditional plant choices, but other small-leaved evergreens, such as Ilex crenata, phillyrea, Lonicera nitida and privet, clip well. For instant impact, you can buy ready-made, but more costly, topiary - expect to pay around 25 for a 30cm box ball. There are many fabulous winter flowering shrubs that deliver rich fragrance, such as chimonanthus, daphnes, mahonias, sarcococca, and viburnums. If they are tucked away at the back of borders, they will get overlooked and be under-appreciated. Plant them instead where their delicious scents can readily be enjoyed, such as close to the back door, in the front garden or beside a regularly used path. Many of these shrubs are happy in pots, so can be moved to centre stage for winter, then shifted to a less prominent position over the summer. Pots are the best way to add a seasonal splash of colour just where you need it. Opt for plants that look good together, such as cyclamen, heathers, hellebores, pansies and variegated ivy. In a large pot, add a shrubby evergreen plant for a bit of backbone, such as a rosemary or sarcococca. At this time of year, all these plants are available in garden centres in small pots, making it easy to mix and match. Warm up with a fire pit or brazier To use your garden on winter evenings, you need to make it as warm and comfortable as possible. There are some great braziers and fire pits on the market these days, which are ready to go and can be placed on the patio for people to huddle around. Most of us spend more time indoors over winter, so it really pays to have attractive views from your windows. Without redesigning your garden, consider what you can tweak to improve the composition. It's amazing what a bit of seasonal rearranging can do. Think about relocating anything attractive that is readily moveable, such as pot displays and garden ornaments, so they can be clearly seen from the windows. Or remove a few of the lower branches of a tree to reveal a view of something eye-catching beyond. Get creative with flexible twigs and weave them into an eye-catching feature. You can buy long lengths of hazel or colourful willow by the bundle, or perhaps you have a plant that can be coppiced? Then bend, twist and weave the stems together to create interesting shapes. Simple woven twiggy balls look great dangling from trees, or make something large and abstract - a representation of an animal such as a deer or an oversized rabbit? Use galvanised wire to link sections together. They wo not last forever, but they are a great project for children. There's nothing better than a project that enhances the garden visually and benefits wildlife. Bug hotels can be simple or fancy, and of any size. Think nooks and crannies. Small holes make ideal hibernating homes for ladybirds and lacewings, so cut bamboo canes into short lengths with the hollow ends exposed. Set them into an old wooden box, or forget the frame and simply tie them into a small bundle. Leftover lengths of wood can be drilled with holes to do the same job, and if placed on the ground then beetle larvae will feed on the decaying dead wood. Perk things up with a splash of paint Introducing permanent colour into a garden through planting alone can be difficult, but painting or staining will add instant colour just where you need it to set off plantings or act as a backdrop. A wash of a water-based colour on large terracotta pots is not permanent, but will jazz things up for a few months. Rendered walls can be painted, while wooden fences and structures such as obelisks or pergolas are best stained, as it's easier to re-apply. Think about which colours would work best in your plot and play around with them. There's a whole range of plants that hold their grey or silvery foliage all winter, fitting the season perfectly. These include: silver bush (Convolvulus cneorum), a compact, spreading shrub with shiny leaves that look as if they've been spray painted; Artemisia 'Powis Castle', with its soft, ferny, pale-silver foliage; and Helictotrichon sempervirens, a grey, arching evergreen grass. They all look great together in a large pot for seasonal interest and can then be transplanted into the garden next spring to provide interest for years to come.
