Solar Street Lamps Are Common in Daily Use
Solar Street Lamps Are Common in Daily Use
First, the lights of solar street lamps flicker and the brightness is unstable. In case of this phenomenon, the first thing is to replace the lamps. If the lamps are replaced or flicker occurs, it can be determined that it is not the problem of the lamps. At this time, it is necessary to check the line. It is not ruled out that it is caused by poor contact of the interface of the line.Second, solar street lamps can only last for one or two days on cloudy and rainy days. The main reasons for this phenomenon are as follows:1. The charging of solar battery is not satisfied. The charging dissatisfaction of solar battery is the reason for solar charging. First, observe the recent weather conditions and whether it can ensure charging for about 5-7 hours a day. If the charging is only 2-3 hours, it is normal. Please rest assured to use it.2. Check whether the solar battery is aging. Under normal working conditions, the service life of the battery is 4-5 years.Third, when the solar street lamp stops working, we should first check whether the controller is normal, because generally, such a situation will occur. A great reason lies in the solar controller. If so, we should carry out maintenance work in time.Fourth, when installing solar street lamps, do not let the solar panels be blocked by foreign objects, so that they can normally absorb solar light for charging. The maintenance and cleaning of solar street lamps should be carried out periodically, especially in some dusty areas, the cleaning frequency should be once a year, while in areas with relatively little dust, the medium frequency rate can be adjusted once every three years to ensure the normal charging of solar panels.For more questions, please click the right figure to consult online customer service.
How to Choose and Adjust Solar Street Light Controller - Blog
How to choose and adjust solar street light controllerSolar street lights rely on absorbing light energy as the source of power to ensure the lighting of street lights at night when the power supply is stopped. So someone will ask that solar street lights are independent individuals, unlike traditional street lights that are connected to a power control box by cables for centralized control. Solar street lights can automatically turn on at night and automatically turn off the lights during the day. Why is this? Because solar street lights adopt intelligent active lighting, this is the role of solar street light controllers, so how do we choose solar street light controllers?The solar street light controller controls all the work of the solar street light lighting system, including charging, power generation, voltage stabilization, battery protection, etc. When choosing the controller, you must choose a manufacturer with a large brand with quality assurance and a complete after-sales system. Generally, the controller is sold as a complete set of solar street lights, so it is very necessary to choose a reliable solar street light manufacturer.Solar street light controllers are divided into two specifications, boost and buck. When purchasing, it depends on the voltage of the solar street light source to determine which specifications to use. This customer has specific solar street light parameter configurations to provide solar energy when purchasing. Street lamp manufacturers, manufacturers will choose according to the LED light source.What specification of solar street light controller has been selected, how should I debug it? Because professional equipment is needed, this is usually done by the manufacturer directly. The customer only needs to tell the manufacturer the requirements such as the lighting time of the solar street light.JSDSOLAR is a professional manufacturer of solar charge controllers , if you need , welcome to contact us.

We most likely have more cars than that and average mileage is 12-15k miles/year. Windmills on top of your car wont work. They would add drag, weight, and require batteries to store the energy so you car runs when its stopped. Small solar panels also do not work. You would need to cover the car with them and it still would not have the power to travel very fast. It needs large expensive heavy batteries too.Why did Bush shut down the solar energy project if we need more energy?he did not "stop" the solar power initialtive..he stopped the pelosi;/reid regime pork barreling that went with it...the only thing it proves is that he uses common sense.electricty is not available at my form house, How i can generate with solar energy (4 lights, 1 fan, 1 tv)?why stop at photovoltaic Sarge? lets go all out and build series of concentrator mirrors to generate steam and run that through a turbine! of course you would need a water cooling tower to condense the steam once it leaves the turbine. unless you want realistic answers...If one half of the solar energy that strikes the ocean surface is absorbed in the first meter, and one half of1/8.... after 1st meter its 1/2...after second meter its 1/4 after third meeter its 1/810 Best Ways To Save Money With Solar Energy (Updated 2021)Energy costs in the U.S. are steadily rising. What are you doing to cut down on your expenditures? Going solar is a great alternative for both cost and environmental reasons. Whether you plan to partially run off of solar or want to truly be off-the-grid, solar power is now a feasible power solution for small and big homes alike. With that said, let's get started. Here's a list of the 10 best ways to save money with solar energy for 2021. Switching to solar power can result in significant savings in the long-term as well. For example, in California, where energy costs are amongst the highest in the nation, the average household can expect to save up to $100 per month or more. Over a 25-year timeframe, the savings can exceed $40,000! Solar technology has come a long way. From the panels themselves to all of the devices which can now operate in energy-efficient modes, switching to solar has never been easier. Oh, and the government can often offer tax incentives if you are planning on installing solar power in your home. Solar energy does not require combustible fuels or connection to an electrical grid. All you need is a good amount of natural sunlight. No pollution, no risk of carbon monoxide leaking, and no need for being tethered to a municipal power grid if you so choose. Not being reliant on fossil fuels also means that you will be reducing your overall carbon footprint. Environmentally-conscious choices help humanity and our future generations to inherit a cleaner planet and one worth respecting. If you are looking to get into solar energy for your home, you will need to understand the basic components that make it work. Although too comprehensive to explain here, the basic components are the solar panels themselves, a battery system to store the energy, and the devices or appliances that are able to use the stored energy. Some states tend to receive more sunlight than others, such as Arizona, New Mexico, and California. This means that they will be able to take advantage and make better use of solar panels than elsewhere. You should always try to locate your solar panels where they will maximize sunlight absorption and avoid shaded areas. Here are a few great ways that you can get started. You do not have to buy all of these products outright, but once you see the benefits and savings associated, you will surely be incentivized to start saving more and reducing your carbon footprint by using the raw power of the sun. 1. Do it Yourself Guide If you are planning on investing in solar energy and building your own solar grid at home, you will need to learn about wiring and electricity so that you can get to work safely and efficiently. Photovoltaic Design and Installation for Dummies is a great crash course into the complexities involved with planning, building, and implementing your own home solar energy grid. Be warned that you will need to brush up on some mathematics and learn a little bit about what an electrician does, but it's well worth it considering that you are doing this to save money in the long run as well as helping out the environment. The best part about doing it all yourself is that you can pick and choose which components will work best for your setup. Which batteries and how much storage capacity will you need? How are you planning to regulate and control voltage? All these questions can be answered by tailoring your solar energy grid to exactly your specifications. Easy to understand for beginners; complex enough for those with some experience Build it exactly how you want If you do not have the time to learn all the ins and outs of building a solar energy installation yourself, then the first step to going solar is a good quality solar panel kit. If you are new to solar energy, there are many things you will need to learn to get started. Luckily, a good kit will include everything needed to start without having to be an expert electrician or having to hire one. The WindyNation 400 Watt Solar Kit comes complete with four 100-Watt polycrystalline panels, ideal for everyday use in homes, cabins, RVs, boats, and more. You will also get all of the relevant cables and connectors required to properly get going with solar energy. This kit also comes with four AGM deep cycle batteries at 100Ahm for storing accumulated energy. Most kits do not come with these, meaning you will have to normally acquire them separately. The problem is that no two batteries are alike. Whether you are purchasing new or used, technologies, as well as lifespans, can differ drastically between batteries. If you are new to solar, you will be happy to have four fresh new batteries to get you started. Of course, you are always going to be able to fine-tune and customize better by buying each component separately and learning the ins and outs of connecting yourself to solar. If you are in need of a quick and easy solution, however, purchasing a good kit is a reliable way to get into solar without having to learn the nitty-gritty. Quick and easy to get started with solar If staying cool is what you are after, you will be happy to know that there are plenty of completely solar-powered fans and ventilators available. One that stands out is the Rand Solar Powered Attic Fan, which is a breeze to install and has enough power to cool up to 700 square feet of space. This fan requires some assembly, preferably somewhere that is able to both get a lot of natural sunlight and also somewhere on your roof that is appropriate for providing proper ventilation indoors. The good news is that once it's installed, that's all you need to do. The fan operates on its own, even on days with some clouds or less sunlight coming in. There's no wiring involved because the unit is designed to function completely on its own. One of the best things about this fan is that you will never need to pay for energy again (at least for cooling your home) and consequently the fan pays itself off easily in the future. Although it's made of good corrosion-resistant materials, it comes with a generous 20-year warranty, which by that time you will have already paid it off in earnest. Great for warmer summer months, solar-powered fans such as this are a great way to introduce yourself to solar energy. Converting energy into heat is unfortunately wasteful. Although some methods of generating heat are better than others, the reality is that if you plan to do any cooking indoors, you will need to be using combustible materials such as propane or butane, or you will need to consume a lot of built up solar energy to use for electric cookers. If you are environmentally conscious, you've probably already ruled out propane or other non-renewable fuels. This leaves you with electric or induction stovetops to do all of your cooking. A great alternative for camping or outdoor cooking is the HUKOER portable parabolic solar cooker. Now it may not be suitable for everyday cooking, but it certainly fits the theme of solar-powered devices. The best part is that it requires no combustible fuels or electricity to operate. Just leave it out on the patio and fold out the reflective array when you've got a good amount of sunlight and let mother nature do the cooking for you. Note that you will need to do a little bit of assembly before it's ready for cooking, but once it's assembled it's quite portable, weighing only 37 lbs. Can be used year-round Along with outdoor cooking, another great option for camping or RV owners without easy access to a hot shower is a good solar-heated water camp shower such as these ones from Coleman. If you've never used these before, a word of caution. There's very little pressure. Furthermore, five gallons is not a lot of water. You wo not be able to spend a long time under continuous flow like you would under a normal shower. If you are careful about conserving your water for washing and rinsing, however, five gallons can certainly get the job done well. By absorbing the sunlight coming in, these bags naturally keep the water inside nice and warm. If you are out camping, secure it to a tree using a little bit of rope or place it near your vehicle if you require a little more privacy. The "showerhead" nozzle has an on/off button for easy access, meaning you can conserve water quickly and easily. As mentioned, it does not have much pressure, but given that it's gravity fed, the nozzle does allow enough pressure to feel just good enough for washing your hair or even doing your dishes whilst on the road. Keeping an entire home or even a room warm enough during the cold winter can be very inefficient in terms of energy usage. Not only is the conversion from energy to heat inherently wasteful, but even great insulation will dissipate that heat eventually. If you are trying to keep warm at night, you want solutions that wo not deplete your solar energy halfway through your sleep and work to keep you consistently warm. The best advice for keeping warm is the tried and tested method of layering. Thick and quality materials like wool socks and big quilts or blankets are a must-have because they work to retain your body heat much like a sleeping bag does. A good electric blanket, such as the Sunbeam Heated Blanket, can be an effective means of keeping warm for those nights where layering up just is not enough. This super soft heated blanket comes with 10 different heat settings and an easy auto-off function, which is important if you are planning to sleep with it on. As with all electric devices connected to your solar power grid, you will want to be cautious not to consume too much energy if you do not have to. Unfortunately, electric heating devices tend to be a hog on your batteries. It is however recommended to have a good and comfortable heating device to get you by, if only on the coldest nights of the year. Less wasteful than propane or area heaters Perhaps the most important component of any solar power setup is the panels themselves. Many years ago, solar panel technology was often prohibitively costly and woefully inefficient. High-quality solar panels can still be a hefty investment, but given that they are now more readily accessible than ever and have proven cost savings, there's never been a better time to invest in high-quality solar panels. Renogy is a brand leader for solar panels, and these 100W monocrystalline solar panels are easy to install and built to last. While 100W wo not get you too much juice for powering a home, it's easy to connect these solar panels to other Renogy panels to give you enough power for everyday use. If you are looking for a durable and high-quality solar panel for a cabin or RV, you will find that these solar panels are a great solution. When paired with other solar panels to make a grid, they are just as good for an off-the-grid home power supply. These products are just a few examples of great solutions that can exploit free and clean solar energy and get you on the path to reaping savings and living fully off the grid. Energy costs are only going up and are already very high in the more heavily-populated states such as New York and California. Potentially saving tens of thousands of dollars over the next 20 years is not only great for your wallet but is also a conscious investment for environmental reasons. It is important to remember, however, that solar energy is not perfect and is still developing. It's heavily dependent on getting a good amount of sunlight and therefore on overcast or cloudy days, you can not expect to spend energy as frivolously as on sunny days when your solar energy grid is generating energy at full capacity. Perhaps the greatest incentive to get started right away is the potential to receive government tax incentives. Many states are incentivizing households to switch to green energy and solar in particular can be a very affordable solution when subsidized. These incentives may not last forever, so do not delay and start considering your alternatives now.

The size of a proper subgroup of a group of order 91 must divide 91. 91=7cdot 13, so the subgroups must have order 7 or 13. Since these are both primes, the only groups of these orders are cyclic. You can see, in fact, that this property holds for any group whose order is a product of two primesDiscrete ordered integral domain and well-ordering propertyAs William Elliot points out, $mathbbZ$ itself is not well-ordered. Actually, the only well-ordered ring is the trivial one, for if an ordered ring contains a non zero element $a$, then either $a > 0$ and $-n.a | n in mathbbN$ has no minimum, or $a 0, exists n in mathbbN_>0, 1 What is a day order? What other types of orders are there?Day order means that at the end of the day, if not filled, it's cancelled.

Can Solar Lights Work in the Dark
Yes, the panels charge batteries that will allow it to work in the dark, until the charge runs out.. .Yes. They put out light in the dark of night and then they charge up when the Sun comes up.. .Solar lights collect solar photon energy during the day through their solar panel. This energy is converted into electricity and stored in the rechargeable (usually Ni-Cad) batteries. A photocell sensor detects whether there is sunlight available or not and acts to switch the lights on based on this. The electricity stored in the battery is regulated by a control board and, at night, the charged batteries provide power for the LED light. Once daylight returns, the panels repeat the process of charge.IBM Thinkpad T20, I want to use some car batteries... how would I do this?If you want longevity but not portability, please plug in the power cable to the power socket. You can run the notebook until the power to your home is cut or your notebook dies. But to answer your question directly, I do not think it's a good idea.How would i power multiple guitar food pedals without batteries?Yes. there's pedalboards and boxes which provide power for multiple pedalsHow to use car batteries for breadboard projects?THOSE SMALL LEAD ACID BATTERIES FROM YOUR LIST CAN PROVIDE AS HIGH AS 30A CURRENT WHILE ACCIDENCELY SHORT BOTH TERMINALS. BURNING THE BREADBOARD WITH SUCH POWER SOURCE AS FAST AS IN SECONDS. UNLESS, AS A SAFE WAY TO USE THEM, INSERTING A 2A FUSE TO LIMIT ITS CURRENT BEFORE LINKING TO BREADBOARD POWER INPUT. THIS WAY, FUSE BLOWS AND CUT OFF 12V POWER IF YOU MAKE MISTAKE ON BREADBORAD CIRCUIT. 12V CAN BE CHANGED INTO 9V POWER SOURCE BY USING A SIMPLE VOLTAGE REGULATOR IC CALLED LM7809.How the batteries in the vehicle recharged during moving?Your vehicle has an alternator, this is similar to a generator. As the engine spins, it drives the alternator which sends power to the batteryiGo electric screwdriver batteries type?if it takes batterys then u should be able to open it some how and then u can tell just on size alone and normally its written on it but if u see a hole in it some where than it probably is a rechargeable driver then u need to find the charger and its not a good idea to open itDoes brand matter for AAA batteries?not really.. but some brands are better quality and will last longer than othersAre my batteries safe to use after I made their contacts touch each other and it triggered a sound and a smell?If was just accidental short circuit then you just release some watts in the atmosphere. You should do a watched full charge. Anyway the charge controller should tell you if is gone. If it is not, carry on and be more careful next time. If they got hot then you just damaged them and you should replace themHow long will these batteries last if the radio has a resistance of 200 ohms?I came up with the same formula as Bill but with 133.3 minutes rather than hours: 240 / .03 = 8000 8000s / 60s/m = 133.3minutes = 2.22 hours Interestingly, the article below (quoting another article!) states: "The amount of charge that travels through a typical alkaline AA battery is about 5 kC = 5000 C = 1400 mAh. After that charge has flowed, the battery must be discarded or recharged." If that were true, we would have 4 * 5000C / .03C/s = 6.67E5 s = 6.67E5s / 3.6E3s/h = 185 hours = 7.7 days. .Solar controller with BJT transistor and PIC24 microcontroller to charge 3.6V NiMH batteriestl,dr: In your case, you do not seem to need charge control at all, and it is more complicated than you seem to sink because of various reasons. Just put a 1N4001 between the solar cell and the battery.The NiMH battery is a quite low impedance, pulling as much current from the solar cell as available at the cell voltage. During charging, it is likely around 1. 4V/cell. This is an output voltage of 4. 2 Volts, so in bright sunlight, you likely exceed the 170mA quoted for the maximum power point, expect something like 200-220mA, which is below C/10 of the cells. I have no idea how you want to do NiMH charging control at widely varying charging currents that never exceed C/10 (no -deltaU, no dT/T seems applicable, but let's ignore that).First thing to notice: Your circuit will not work as drawn. You drew a NPN transistor. It needs a voltage at the base that exceeds the emitter voltage (by around 0.6V) to make it conductive, but the uC has no access to provided the needed 4.8V (battery voltage 0.6V). You need an PNP transistor instead. In that case, you need to to provide current from the base terminal to a more negative sink. Also, you would connect the emitter to the solar cell in that case. Note that to turn off the transistor, you need the base voltage to go up to 0.5V below the unloaded solar cell voltage, this is around 8V. Start with the desired collector current (220mA maximum cell output) and take a look into the transistor data sheet. Let's choose a BC327 for it's higher current rating compared to the typical 100mA transistors. Take a look at figure 4 (Saturation region) if you want to have low losses on the transistor, which seems like a good idea now (but see later). They have curves for 100mA and 300mA collector current. As we do not have a lot of energy to waste, choosing a base current at the low end of the neary flat end of the saturation voltage curve is a good idea, which yields something around 4mA if you interpolate between the 100mA and the 300mA curve. To turn in the transistor, at 4.4V solar cell voltage, 200mV transistor drop, and 4. 2V battery voltage, you need to sink 4mA at 4.4V-0.6V (emitter-base voltage). To turn it off, base must rise to 8V (see above). This means, you need a pull-up resistor between base and emitter, providing the turn-off voltage from the cell instead of the uC and a diode (1N4148 will do) to protect the uC from that high voltage. So the circuit looks like this: PNP with emitter to solar cell, and collector to the battery. A resistor connecting emitter with base (the value does not matter much, and something around 100k will provide enough pull-off effect without disturbing the circuit while the transistor is on), a diode and a resistor in series to the uC. The uC needs to sink 4mA to turn the transistor on. This results in an output voltage of 0. 4V. So the resistor has to sink 4mA while having 0.4V above ground on the uC end and 3.8V above ground on the diode end. 4mA at 3.4V is 850 ohms. So 900 Ohms in your circuit does not seem off that much.You will not be happy at all with that circuit for different reasons, though: Constantly sinking 4mA takes too much of the charging current (getting 220mA outdoor on a bright sunny summer day is one thing, on cloudy days, being inside, expect something like 10mA maximum), and you are wasting 4mA of that just to turn that transistor on. Furthermore, when it gets dark, the solar cells draw power due to their leakage current and discharge the battery by operating the transistor in reverse mode (collector acts as emitter, base current is provided by the solar cells and the 100k resistor meant as pull-up, and the emitter acts as collector). Common wisdow is you need to protect against that, for example by putting a diode between the collector and the battery. You will lose voltage there, though. Another possiblity would be a "secondary pull-up" that will pull the base up, even if the emitter supply (the solar cell) fails to provide power, by connecting a resistor from collector to the base terminal. This resistor has to be low enough to pull the base up against the 100k that pulls it down, so go for something like 20k there. Of course adding all these resistors does not make the thing more efficient.Actually, your charging current is very low compared to cell capacity. As estimated above, you only get to C/12 on extraordinary good conditions, you the charging current can safely be considered as "trickle charging" unless you put the device into the beam of a bright headlight 24/7. You do not need any charge control. You just need to prevent discharge through cell leakage, and this can be povided by a single diode between solar cell and battery

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

Good reputation manufacturers, the quality will not be too bad, if most people feel bad, then the word of mouth will certainly not be good. To understand whether this 50W led solar street light manufacturer's reputation is good, it is necessary to understand through the various platforms of the network, the majority of netizens will tell you.Secondly,look at the strength of the manufacturers.The strength of the 50W led solar street light manufacturer is very important, why do you say that? Because if a manufacturer has strong strength, the scale of the factory is definitely large, and there are many suppliers. They can have multiple choices and can give the most benefits to customers. Not only that, but powerful manufacturers can provide you with more advice and more professional services.Thirdly,see the detailed configuration of 50W led solar street light.If you want to choose a 50W led solar street light with a high cost performance, you must see the detailed configuration of the street light. Things that are too complicated can not, but the power of the lamps, the size of the panels, the capacity of the batteries, etc. will all need to noticed.Because the market for virtual standard capacity is getting stronger and stronger, if you don't know how to distinguish it, you will probably lose.In addition, if you don't know some 50W led solar street light knowledge, the mastery is in the hands of the other party. I don't know what the overall effect is, and this is the most wrong.Fourthly,look at the warranty time.Under normal circumstances, the warranty time of 50W led solar street light is 1-3 years. The longer the warranty period, the better the quality of this product and the relatively high price.In short, if you want to choose a 50W led solar street light with a relatively high cost performance, you must know the above four points. Whether it is the reputation of the manufacturer, the strength of the manufacturer, or the basic configuration of the 50W led solar street light , more or less must know some, so that you can choose the most suitable one after shopping for three!·RELATED QUESTIONWhy don't hotel rooms have ceiling lights?My hotel building is over 100 years old, so we have ceiling lights. We also need a ladder to change a bulb 11' from the floor. It can take 20 minutes for 1 bulb! This is one reason that we have changed to the longer lasting (and more economical) low-energy bulbs.I would be delighted to have wall lights instead. Retro-fitting them would however be even less economically sound.Higher than average ceilings mean ladders to change the bulbs in ceiling fittings, and this extends the maintenance time and convenience for staff enormously. Even normal height ceilings mean that a chair is needed to swap a bulb out. Wall fittings are so much more convenient for both staff and customers, reducing the time taken to get light again!As Michael Forrest Jones says - anything other than a simple bulb swap requires the power to be cut to the whole circuit (which may be more than just a few rooms). This makes it very awkward to do emergency repairs after dark! -- Been there done that... Go with wall fittings that can be isolated in-room!In short:I have ceiling lights.I don't like them, as they are awkward for maintenance.Replacing them would be expensive and extremely difficult - basically a total rewire of the hotel lighting system.Design engineers are not stupid. they note the first 2 points!
