Journals and TV reports have shown many people who...

    Building A Solar Power

    Shawn Said:Can solar power be used to power a building with about 4 airconditioners?We Answered:You're going to need a REALLY big solar panel. A reasonable rule of thumb for AC loads is 1 kW per ton of cooling capacity. (1-ton is equal to 12,000 BTU/hr). A typical residential home might have a 3 to 5 ton AC unit. If you've got four 5 ton AC units, that means you need to produce 20 kW of solar power. Keep in mind that these values are just to keep the AC running. The compressor's starting inrush is roughly 5 times...

    Building Solar Panels

    Cynthia Said:If I were to install solar panels on a building...?We Answered:It's not that easy. Generally the placement maximizes sun exposure while minimizing hazards, threats, and expense: * South facing in the northern hemisphere, angled upward from level approximately by the installation's latitude. At the equator, they can lay flat. At the north pole, vertical. * Away from chimneys, flue vents, overhanging trees, etc. * Minimize strong wind exposure—or at least decrease deleterious effects of strong winds being able to uplift or remove the panels. * Reasonably convenient maintenance access They need not sit directly on the roof—called "flush mount". Usually...

    Compare Solar Panels

    Christy Said:How much CO2 is reduced by solar panels compared to how much CO2 is required to manufacture them?We Answered:Hey WLTK, that article you read is probably dating itself, I'll explain why. There was an argument that solar power is a bad idea back in the 90's because it was estimated that a solar panel will never produce as much power as was used in manufacturing it. There were several studies done on the subject, probably the most indepth was done by Solar Energy International. What they are referring to is the, "Embodied Energy," in the panel,...

    Disadvantages Of Solar Power

    Misty Said:What are the disadvantages of solar power?We Answered:Solar batteries produce electricity by a photoelectric conversion process. The source of electricity is a photosensitive semiconducting substance such as a silicon crystal to which impurities have been added. When the crystal is struck by light, electrons are dislodged from the surface of the crystal and migrate toward the opposite surface. There they are collected as a current of electricity. Solar batteries have very long lifetimes and are used chiefly in spacecraft as a source of electricity to operate the equipment aboard. See Solar EnergyDay, in chronology, period of time required for...

So let's say 140 watts and then we'll throw on a bit extra in case you want to run anything else: 175 watts. Double that because the sun doesn't shine from 6 til 12pm and you'll need to charge a storage battery when it does shine: 350w. Converting the DC power to AC power will incur you a...

    How Do Solar Panels Work

    Lois Said:how does solar panel works ? basic principle?We Answered:Solar electric panels are made up of something called silicon, the same thing that makes up sand. There is more silicon on the planet than almost anything else. Even though you can find silicon almost everywhere, making a solar panel is difficult and expensive. The silicon has to be heated to super high temperatures in a big factory, and then formed into very thin wafers. When sunlight hits a solar panel, it makes electrons in the silicon move around. (Electrons are teeny tiny specks--they?re way too small for us to see,...

Maybe you would use a computer with a tuner card in our computer as your TV, to save space? A flat panel display uses a lot of power because of its backlight. If you get a modest laptop, it might use 50 watts. You can get a computer that uses 7 watts, or even 1 watt, but that type will be very limited (uses flash instead of a hard drive). I'd allocate 1 kWh...

    How Solar Panels Work

    Joy Said:Can solar cookers have copper panels does it work better?How do you use it?We Answered:Copper is a very dense metal and an excellent conductor of heat. It also doesn't react with water as rapidly as cast iron. If you wanted to have a water table in your solar cooker to basically make a solar steamer (the water helps to hold the heat but these cook very slowly and are basically solar crock-pots) you would use copper panels on the interior surfaces that are in contact with the H20. You would have your heavy cast iron surface...

    Off Grid Solar Power Systems

    Ricardo Said:what kind of sensor would i need for this project?We Answered:It seems to me that you want to measure voltage and current from the solar panel to compute power in, and voltage and current out into your environment to calculate power required. You need 4 a/d inputs, possibly built into a single chip uP that you use for control, such as the ATMEGA128 or smaller. 2 uP inputs measure scaled voltages from the input and the output. 2 uP inputs measure current from the input and the output by voltage drop across a sample resistor.

    Origin Solar Power

    Daryl Said:Carbon-14 Dating Questions?We Answered:1) The decay formula is N(t) = N(0)e^kt where: N(t) = amount of carbon 14 remaining after t years N(0) = initial amount of carbon 14 k = decay constant t = time in years Unfortunately problem 1 has two unkowns; k and t. However, the half-life of carbon 14 is known to be approximately 5730 years. Since we know the time and the amounts, we can calculate the constant k. N(5730) = [N(0)e^(k*5730)] Since after 5730 years, 1/2 will remain, then N(t) = N(0)/2. N(0)/2 = N(0)e^(k*5730) cancel out the N(0)'s on both side and replace with 1's. 1/2 = 1*e^(k*5730) ln(1/2) = ln[e^(k*5730)] -0.693147181 = k*5730 k...

    Solar Panels Installation

    Ruben Said:Please help with my solar energy installation?We Answered:I would worry about overcharging the battery. For the use you are describing, it is likely that the solar panels will put out more energy than your pump and inverter will use. You can tinker around to see how many panels will do the job, and use as few as possible. Still, it might be necessary to use something like a resistor bank and zener diodes to keep the maximum voltage around 13 volts. Also it is likely that you will want to run the inverter only when the timer...

    Solar Power Battery Chargers

    Alex Said:could solar battery chargers help fuel economy?We Answered:I'm not sure if that much fuel goes into recharging a car's battery. I believe that once a car is running, you could remove the battery and it would still keep running. That suggests to me that the only energy someone needs to replace into the battery is what was used when first starting the car. When you see solar battery chargers on the market, those are usually for keeping the battery alive in a car that isn't driven much. For example, if I park a car up at a...

This is because these companies...

    Solar Power Business

    Jessie Said:why arent businesses doing more to promote solar power as the fuels we have are running out?We Answered:Yes money is a factor, but it relates to the actual energy produced. Until recently it took more energy to make a solar pannel than it would ever produce in it's working lifetime. For that reason solar pannels were only practical in places or things where connection to the electricity grid would be impractical. Since then the cost of making solar pannels has improved considerably both in terms of energy and costs. Howeve they are still about the most expensive way to make...

    Solar Power Calculator

    Dennis Said:Why don't solar powered calculators work with low energy light bulbs?We Answered:Hi! Solar cells do not convert all light into electricity. They need light of specific frequencies to work. Incandescent light has lots of light in the red end of the spectrum and this is what solar cells need. Fluorescent lights, including the low-energy ones, produce most of their light at the blue end of the spectrum. Unfortunately solar cells are not very efficient at these wavelengths. That is why you can get it to work, but need to hold it almost under the light to get enough light on it. If we...

    Solar Power Generator For Home

    Louise Said:electricity/internet hypothetical question...?We Answered:Ok, power plants would probably continue to work unless something went wrong. The problem would be that the power consumers (mostly heavy industry) would fail, which would reduce electricity consumption, which ordinarily would lead to some power stations switching off while others would continue supplying the remaining load. Which probably would lead to something like the last East Coast blackout, i.e. one emergency overload trigger could cascade through all of the network and shut it off. Without anybody intervening, that would be it. Getting a generator or solar panels to work is easy, so unless they're a...

Also how many hours a day do you expect to operate the fan. Finally, where are you located and how many hours of direct sun can you expect per day. I'd get a 12 volt battery, size depends on the above missing info. And a 15 volt panel,...

    Solar Power How It Works

    Gina Said:Do I have to change batteries in solar power lights often?We Answered:My solar power lights take rechargeable batteries. It's hard to say how often you'll have to replace them.

That's where the 50/60 Hz comes from, that shows how many times a second the charge alternates, hence, alternating current. AC is used for pretty much all wall-plugged things, and I'm not sure if DC will damage them, but they might not function as properly. For example, such things as pocket guitar amps, and keyboards (musical) can use transformers to provide them their 7.5 or 9 Volts and it would be DC, just...

    Dolores Said:why is solar power renewable?We Answered:The sun provides free and renewable energy, and attempts to make use of it go back well into the 19th century. However, its utilization poses two problems. Solar energy is very diffuse and has to be concentrated if it is to be used as an alternative to fossil fuels. It is also difficult to store, and it must therefore be supplemented by another energy source, such as electricity, to provide energy for heating water, when the sun is not shining. While one does not have to pay for the energy one absorbs sitting in...

    Solar Powered Ac Units

    Tracey Said:Am I the only one who thinks this would be a good idea?We Answered:I like it! The beauty is that the more you need it, the better it works! The closest thing to a solar-powered a/c unit on a car is the solar-powered exhaust fan they had on the Mazda Millennia. One problem is that the area of photovoltaics needed to power an a/c compressor is greater than you could conveniently fit on the surface of a car. At maximum cooling, an a/c unit in a car uses about 4kw. Photovoltaics in the sun belt can deliver about...

    Solar Powered Air Conditioner

    Scott Said:can solar power support a room air conditioner 240V 1.5amp?We Answered:Theoretically it could. But the machine you describe uses only 360 watts, whereas even the smallest units usually burn much more. If your A/C is real, then you will need panels of at least 500-800 watts (remember the rating is for direct full sunlight) because of losses in the inverter (DC to AC current). I just bought 150 watt system and paid $700 wholesale, so you would be looking at maybe $4k or so, depending on where you live and your tech ability. better to move...

    Solar Powered Air Conditioners

    Patricia Said:Do solar powered air conditioners really work?We Answered:Some good answers there on Absorption chillers etc. Solar powered air conditioners are the air conditioners of the future. At present the power rating of the AC requires a big solar panel to give the necessary energy to run it. So in fact we cannot call it a solar powered one. But in future the same concept can be converted into a more efficient and compact unit where by the solar panel will be part of the AC and then we can call it a solar powered AC. I am confident the...

    Solar Powered Boat

    Clayton Said:Would a muscle powered hybrid make sense for a boat's drivetrain?We Answered:Tahini: You should concentrate on the "muscle to electric generator" interface, with which you generate electric power or propel your craft. Reasons for my "warning": 1. Muscle Effciency. One of your issues is the vast difference in efficiency of the human muscle as a function of its contraction speed (from near 100% down to maybe 10%). The automotive equivalent is the well known "torque vs RPM" plot. Your muscles in effect perform like a race car, their plot being a steep "needle", in comparison to a more desirable FLAT...

    Solar Powered Car

    Irene Said:Is it possible for a solar powered car to exist?We Answered:No. At least not without a major break through. A car, even with solar panels on the roof, hood and trunk would not have enough surface area to get enough sunlight to make the car run. Solar panels are just not that efficient, and work best in direct sunlight and in most places that is only for a couple hours a day(10am to 2pm). And you would need to keep the panels clean, and cars get dirty fast. and replace them often. And there is the battery...

    Solar Powered Energy

    Steve Said:solar powered?We Answered:Anything outdoors, that is very far away from an electrical outlet, is a particularly good candidate for solar power. It can be expensive to run power cables long distances. So solar is often used for remote water pumps for animal troughs in fields, or lighting road signs on remote roads or even yard lighting. Obviously, anything CAN be powered by solar energy. But these are the sort of applications where solar power is currently very cost effective - and thus where solar is used a lot.Marc Said:what exactly is solar powered energy?We Answered:Light consists,...

The environment that gave you the opportunity to get such a great deal on the house is also going to make it very difficult for you to get a loan. The marketplace for alt-a (good credit, unusual terms/situations) and sub-prime mortgages (poor to bad credit) doesn't really exist at the moment. Your best bet is a...

LEDs that are used to light pathways at night are not intense enough. Same with your indoor plants. If low light is OK for them, the artificial light will be fine. If they need more intense light, adding low light for a few more hours per day will do nothing for them. If you have plants that require intense light, give it to them at night when no one is around to be...

    Solar Powered Light Bulb

    Don Said:can a light bulb power a solar panel?We Answered:Yes light-bulbs work, sort of, but you have to illuminate every cell. The output is regulated by the cell with the weakest illumination. Additionally the sun is very strong, 1000W of light or more per square meter. A light-bulb is weaker, so less output. A 100W bulb may have only 5W of light, and it doesn't cover the panel, so you can expect something like 1% of the sun's output. The spectrum of a light-bulb is actually more appropriate for a silicon solar panel, as the silicon panel responds best to red...

You need to keep it as light as possible, and not weigh it down with too many batteries and motors. As far as actual volts go, I'm not sure. How large is it? You also are going to have to evenly distribute the weight, as well as have enough lift being generated by the rotor. You can do this through trial and error.

    Solar Powered Panel

    Bruce Said:Can a solar panel be powered by other sources of light than sunlight?We Answered:in principle yes However, to produce the light intensity equal to sun radiation you'll need to invest so much more electricity that it is simply not economical. You loose twice, once the conversion efficiency of the light bulbs (amount of electrical energy converted to light) and second the efficiency of the photovoltaic panel. It might be that you invest 10 times more energy to produce the light than what you recover in back! http://www.solar-energy-for-home.com/off…Julia Said:Can a solar panel be powered by artificial light?We Answered:Years ago I saw...

Poroblem is energy to mass ratios, the surfcae area you would need to generate enough electrical power to sustain flight, using any forseeable solar panel design, would weigh just too much. And adding more panels would only take you farther down the path of not getting off the ground instead of helping. If you wanted to store energy for later or emergency use, or during low or no...

    Becky Said:How can I extract current from Solar Cell?We Answered:There is lots of ways you could do it. Simply connecting the leds across the solar cells will cause them to light up. However, such a method has a few problems. The leds will only light when there is light illuminating the cells. Voltage fluctuations will be so great, you will almost certainly blow the leds. Light from the leds will vary from nothing to max. In other words, no control. Using any storage mechanism would be preferable. You could use capacitors, inductors, gravity, inertia to name just a few. Most have...

Sunjet 150 http://www.gardenwinds.com/servlet/Detai…Javier Said:Solar powered water pump for sprinkler?We Answered:This project may be very poorly considered. Solar power is costly on a capital cost per watt basis. You would want to use that costly power to do things for you all year round, not just when your garden needs water. For any pumping role, your solar panels will not provide good starting ability, particularly when the sun comes up. You will need battery power to build up some charge to start the motor under...

    Solar Powered Pumps For Ponds

    William Said:wondering about desalinization of seawater....?We Answered:That is one idea. I´ve been thinking about a glass structure. Maybe a hybrid. A half pipe, black in the bottom to absorb sunlight and covered with glass to let light in and trap the heat. If its airtight you can use a compressor to suck the humidity out while lowering the pressure in the structure which makes it easier for more water to evaporate. The vapor sucked out is compressed into a tank until it becomes liquid again. This also raises the temperature quite alot. You use fresh, cold seawater to cool it...

    Solar Powered Pumps

    Irma Said:Does anyone have experience of solar-powered water pumps - for household & irrigation purposes?We Answered:I installed one as part of a environmental remedial system. I cobbled it together myself with a PV panel from a discount mailorder company, a large automotive battery and an invertor from Westmarine (their catalog is pretty good for off-the-grid stuff). The invertor conveniently shut itself off when the voltage dropped so no more control scheme was needed. And the pump was higher wattage than the PV panel so the battery could never be overcharged. I haven't used grundfos' solar pump, but I've...

    Solar Powered Radio

    Milton Said:I am having trouble finding the right emergency weather radio. Shortwave..NOAA..CRANK ...SOLAR POWER?We Answered:NOAA All Hazard Radio, the new name for NOAA Weather Radio, is designed for local area warnings only. Therefore, a shortwave frequency is not used. There are two main reasons for this: 1. Warnings are best handled by the local NOAA National Weather Service office which is responsible for most local warnings, advisories, and forecast. This lower power broadcast will make it less likely to interfere with another distanced NOAA weather radio station that is broadcasting at the same frequency for their local area. 2....

    Solar Powered Refrigerator

    Agnes Said:How much power(solar) do I need?We Answered:Let's look at best case. Let's assume you're tied to the grid right now, and will stay tied to the grid, so no batteries will be required. A good refrigerator will use only 1 kWh per day. That's an acceptable amount to get off of solar. The air conditioner is an entirely different matter. If it's just a little 5000 BTU wall unit, you can use a crude rule that every BTU is 1 kWh per year (see the link below). That means 5000 kWh per year to run the A/C under average...

    Solar Powered Satellites

    Miguel Said:What are some cons about Solar power satellites?We Answered:As the satellite gets farther from the sun, the available solar power drops off. This is not much of an issue for satellites orbiting earth but for things like the Viking probes and Galileo, solar panels were not included. Solar panels are somewhat fragile so they can be easily damaged by micrometeors. They don't work when the satellite is in shadow. They usually have to be folded up during launch so you need moving parts to unfurl them once in orbit. You may be able to...

    Solar Powered Street Light

    Sally Said:How many days of sun light does it take to power one street light?We Answered:A typical street light might be 250 watts. A solar panel might collect 25 watts per square meter. When you consider clouds in most places half the time, you would need 10 square meters of solar panel to run one street light. Then there is all the energy needed to make the solar panels, and install them. So the answer is: 182 days of sunlight, and a BIG solar panel, to power one street light for one year. Wouldn't it be better to put...

    Catherine Said:Need an expert on solar thermal power plant (10 points for the most helpful)!?We Answered:1. depends on what kind of crew you have. probably about 1 year (for a large one) 2. anywhere that doesn't have trees, maybe in the south? 3. solar panels collect the suns rays and convert that energy into usable energy that is sent to house or other buildings 4. we don't have to burn anything and that is a good thing.Tonya Said:Why do most people forget about solar thermal when it come to talk about solar power?We Answered:They dont realize it even exists. alot of clueless...

    Solar Water Heater

    Joe Said:How does a simple homemade solar water heater work?We Answered:many years ago, when i was in Hawaii, i found a shower in an almost unused country park. it was wonderful. there was a water tank on top of the concrete structure. when you turned the shower on, you got water that had been heated by the sun. no pumps, no tubeing, no nothing. just the water tank, out in the sun. more typical systems have a black panel, with a tube network, and a pump that circulates water from a tank through the panel. water is recycled through the panel, and the tank, as long as...

    Solar Water Heating

    Tonya Said:Udaipur city uses solar water heating technique.........are you aware?We Answered:cities all over the u.s. uses solar thermalVernon Said:Which would be better choice in a solar heating systerm: water or ethanol?We Answered:water has a higher specific heat, so it makes a better means of heat transferBobbie Said:has anyone in the UK had Everest solar heating fitted for hot water, if so how much did it cost?We Answered:They wanted to charge 2 X 4500 for my 4 bedroom terraced house. If I had accepted I had to wait at least ten years to see any saving. When I said no they...

    Solar Wind Power

    Margie Said:solar/wind power question?We Answered:It is not that easy to answer your question because it is a function of size and type of wind turbine or solar panel. An average Home Solar Panel is about 3 ft. X 4 ft. and will produce maybe 30-40 Watts when the sun is around peak position. Remember, this peak is only a few hours a day. Lets say each panel would produce 50 Watts for 5 hours a day and less for another 5 hours, and the average is 30 watts/hr over the 10 hours it can produce any power. I would need...

    Stand Alone Solar Power

    Margie Said:Christians, Atheists, the truth to the universe?We Answered:That's good to know. Thanks for sorting that out for us!Jay Said:Where do you stand on nuclear energy?We Answered:As a former nuclear power technician, I think a modern conservatively designed nuclear power plant can operate safely and efficiently. All of the electric cars in the world will not solve the fuel problem if we do not build the power plants to recharge their batteries. Wind power, solar power, wave power, all are intermittent but nuclear is very consistent. The US Navy has operated more nuclear power plants for more hours...

    Sun Power Solar

    Cindy Said:Can solar power items work with a lightbulb rather than the sun?We Answered:Yes - but you have to have power to make the lightbulbs work, so you actually lose energy. If, however, you're perhaps hoping to use a solar-powered calculator for a final exam, take it into the room before hand to be sure that there's enough light to make it work.Billy Said:sun and solar power questions plzz help me ^_^?We Answered:1 Radiation from Sun. 2 Yes.Very small forceArthur Said:How come solar power in sun drenched equatorial coastal areas isnt used to convert sea water to fresh water?We Answered:It...

    Sun Solar Power

    Agnes Said:Is it only possible to harvest solar power from visible light from the Sun?We Answered:The answer to your main question is a hesitant "yes". From the ground, the higher energy photons do not get to us. They are blocked by the atmosphere. We could use the lower energy photons (infrared or radio) but since they carry a lot less energy, they are far more difficult to "harvest". Still, using black pipes arranged in a tight circle on your south facing roof, it is possible to heat your pool water: this captures the energy from the visible light AND some energy...

    The Future Of Solar Power

    Jeffrey Said:what is the most effective means of supplying power for future needs?We Answered:What will be most effective is going to be highly dependent upon available resources. Unless there is some miracle way to make hydrogen that defies the law of conservation of energy it seems like a poor choice. Solar is going to work in many places but will be most effective where it is most available, in sunny areas. The same will be true of photochemical means. Wind generation is going to be most effective where there is available wind. If we use...

    Types Of Solar Panels

    Lonnie Said:which type of solar heater is better? one that uses pipes or panels?We Answered:For heating water, all the panels have pipes in them - it just may not be so obvious in some. Maybe what you are thiking of is evacuated tubes? There is a certain kind of heating system where antifreeze instead of water flows through the thing on the roof. Then the hot antifreeze is pumped below, where it heats water. The advantage of this kind of system is that if you're in an area where you have to be careful of water pipes freezing...

    Uk Solar Power

    Elmer Said:Should the UK build more Nuclear Power Stations?We Answered:Yes, And america needs more too.. I would LOVE to supply all energy from solar, wind, geothermal, and hydro power.. But the reality is... Nuclear power is a very good aternative, at a significant cost savings, which works anywhere, with NO greenhouse gas emmissions.. Why we dont use it more already confuses me.. Yeah so it produces nuclear waste... So does our city hospital... No one protests that... So does a smoke detector factory... No one protests that either.. So does the earth *in the form of radon* which actually is the second leading cause of...

    Used Solar Panels

    Alfred Said:where to find used solar panels?We Answered:Used solar panels can be effective, provided they are in good condition. Make sure to test them for effectiveness before paying though, so you don't get ripped off. Try reading here: http://ezinearticles.com/?How-to-Buy-Pre…Nancy Said:How can you use Solar Panels, Wind Energies and Dams as a renewable recouurce?We Answered:Okay... this seems familiar... Well then. Solar Panels harvest energy from the sun. Sometimes, panels are used to create electricity via photons from the Sun's rays. Other times, the panels are simply deflectors that are used to boil water in a tube where the sunlight is concentrated. Pro: The Sun...

    Water Features Solar Powered

    Dorothy Said:[HOROLOGISTS AND SERIOUS PEOPLE ONLY PLEASE] Is there a watch that has ALL of the following features?We Answered:I doubt it. Sorry.Charlotte Said:backup to solar power?We Answered:You could add a battery in parallel with the solar panel, but only if the panel provides more power than the pump uses. Since it would be wasteful to use a bigger panel than the pump needed, they are probably pretty well matched. So you'd need to add another panel, probably a bit larger than the existing one [depending on how long you want it to run]. Simplest might be to get one...

    Water Power Generator

    Lucy Said:has anyone built a hydrogen generator from "bill power's" "run your car on water" plans??We Answered:bill is in jail with Dennis Lee and Paul Pantone for selling frauds. Just google those names and get the WHOLE story.Jared Said:what do you need to connect your generator to the power grid?We Answered:You need a reversible meter for the easy part. Disconnects for safety are also easy. The difficult part is the controller to make sure your power is in phase with and stays in phase with the grid power. If it isn't in phase it is just...

    Water Powered Generator

    Jeanette Said:Water-powered electric generator?We Answered:You need "head" and volume. It sounds like you have volume but you also need to have a vertical differential: the water source needs to be probably at least six feet above the generator for starters. If the stream is higher a ways back, you can run a pipe.Andy Said:Can i build one simple generator that is powered by wind or water? How?We Answered:The question i'd ask is, is this about building the generator, or about comparing the difference between wind and air? it's my guess that it's the latter, so the source of the generator is...

    What Is Solar Energy

    Andrew Said:What is a down side to solar energy?We Answered:I think the only down side is that no electricity is generated at night. As for other answer mentioned energy used to produce panel, here is a interesting fact: The energy payback time (i.e., the time it takes for a PV system to generate the same amount of energy that it took to manufacture the system) for PV systems is 2 to 5 years. Since a well-designed and maintained PV system will operate for more than 20 years, and a system without moving parts will operate for close to 30 years, PV...

    What Is Solar Power Energy

    Heather Said:if we use solar powerd energy 50 years from now how will out enviroment be like? look like?We Answered:Although it is technically possible to have a virtual paradise on earth if we used solar power exclusively. We could even still use gasoline and diesel powered cars running on synthetic gasoline and diesel made from CO2 and H2O with solar power (Sandia Labs Sunlight to Petrol project). But will it happen? The problem with solar power is that it's decentralized and hence companies can't charge a monthly bill for it. Sure...

    What Is Solar Power

    Peggy Said:If we built a base on the moon would solar power be enough to run it?We Answered:No...they would most likely use the "solar winds" to provide energy. Sort of like a windmill that creates electricity with light energy instead of wind. It's still energy but not stored by voltaic paneling....

    What Is The Cost Of Solar Power

    Sue Said:what would be the cost of a 50 mw solar power plant?We Answered:This is similar in scale to the proposed plant to be built near Austin, TX. That plant would be 30 MW, and cost $180 million. If we take the same $6/watt, the 50 MW plant would be $300 million. Wait a few years, and it will be half that.Bessie Said:How much do different power plants cost?We Answered:well, it depends on where u are building them , but for the most common plants like fossil fuesl based thermal plants , burning gas or oil , u...

    Wind Power Solar Power

    Amber Said:Wind and Solar Power Question?We Answered:No matter how it is done, wind power cannot be as efficient as solar power - in the sense that wind power is already second-hand solar power. That said, though, the ''efficiency'' of either of these systems is a bit difficult to quantify properly. Typically, an engineer might look at them in terms of ergs per square meter of land used - - and location and local climate will have a huge impact on these. Cost - variable... for either. Both can be achieved with relatively minimal costs (depending upon exactly what effect is desired) -...

    Wind Power Solar

    Betty Said:Why does the left keep talking about wind-solar power when they know that it cannot workWe Answered:Because the left wants it to happen and that is enough to them to believe it will. You are trying to use logic with people who do not use it. The simple problem is the left buy into the notion that oil is evil. The only evil with it is that bad countries have it. If we find our own, we do not need theirs. ...
