Fast Facts about Solar Power
Solar power is by far the most widely used type of renewable energy. Spain and Germany have the most solar power plants in the world, but other 00004000 countries in Europe, Asia, and America are utilizing this to power their growing society.
Adequate resources
This energy source is widely available to the world, unlike other renewable forms of energy that are only limited to some countries. Tidal power, for example, cannot operate in areas that do not have strong and large waves. Wind power can only operate on breezy regions of the earth, while geothermal power is inapplicable to areas that have a greater distance to the earth's core. But solar power can be created anywhere as long as there is the sun that is shinning.

QUESTION:
Where can I buy a solar powered car?
I'm looking for one that's solar, legal, and doesn't look stupid. I've seen them on the links below but nowhere to order any. Also, how much are they? (don't say"very expensive")Awesome Car Right Here ----> http://www.aboutmyplanet.com/alternative-energy/solar/facts-solar-powered/
Another Cool Car ---> http://peswiki.com/index.php/Image:Koenigsegg_quant_95x95.jpg
P.S. I don't care about the speed as long as it goes faster than people walk.

ANSWER:
They do not yet exist in the market. No car that could only go 30 MPH could be licensed for the public roads.

QUESTION:
Solar powered cars?
I have to do a 1 page report on solar powered cars, so I was wondering if someone can give me some quick easy facts about solar powered cars, or a good website to research them.-
ANSWER:
Why is it that a kid who can use Y!A can't manage to Google? Ah, sheer laziness!
Well, if this site won't do it, you'll need to actually look up something on your own -- gasp!

QUESTION:
Facts about renewable energy? (solar, wind, etc) please answer?
I'm doing a poster on Renewable energy, and I would just like someone to verify that all these facts are correct:Clean energy poster:
What is clean energy?
This is power produced from renewable (naturally replenished) and natural resources without having a negative impact on the environment.
Examples of reliable “clean” energy sources include: sunlight, water, wind, biomass and geothermal heat.Wind Power – this is the conversion of wind strength into usable energy sources, especially for electricity. This type of power can be obtained by using wind turbines and wind mills.
Solar Energy – this is the power that is obtained from sunlight and can be converted into other types of energy. Inventions such as solar panels can help collect this source of energy for conversion.
Biomass Energy – Biomass is any plant (trees) or animal matter, and can be used to create an energy-rich gas called Biogas. Biomass can also be burned to create fuel for different uses.
SOLAR ENERGY
-This renewable source of energy does not produce waste or pollution.
-This fuel is used for many things: electricity, creation of biomass, heating water, and buildings, and even transport (solar-powered cars)
-This is a free, reliable and clean energy source.WIND ENERGY
-This is one of the lowest priced renewable energy sources.
-This renewable source is a good alternative to nuclear energy in areas with favourable climate conditions.
-This source can provide cleaner air and a much healthier environment for all.BIOMASS ENERGY
-Growing biomass for fuel can create jobs in rural areas.
-Biomass is not a fossilised fuel (like oil and coal), but fresh natural material that can grow again, even after harvesting.
-Using this source of power will not have a major affect on the environment.Is everything correct/accurate? anything that I should edit/change?

ANSWER:
Biomass does not create bio fuel, yet.
Biomass is usually sent to a biomass plant that converts it to electricity. Yes it is small trees and brush or even walnut shells that are chipped then burned in a massive furnace heating water into steam that turns a turbine generator that produces electricity.
It can be converted into ethanol gas but currently its to expensive to pay off.I'm a lumberjack

QUESTION:
How much solar power is necessary for my 850 W PC?
I have some plans considering a new PC I am planning to put up.Now then, My plan is to buy some strong power supply unit for the PC.
In the past, I didn't payed attention to this factor, until a friend of mine, while playing Call of Duty:Modern Warfare 2 had his PC dead because the 500 W power supply died from overheating.
He bought new 600 W power supply and his PC is now 100% OK and up and running, considering the fact that the new power supply is from Cooler Master and it costed him , while his PC case with the old cheap 500 W power supply that died costed him about .And that is why I am planning to put a 850 W power supply in the new PC, considering the fact that I might use NVIDIA SLI or ATI Crossfire.
I am not very familiar with solar panels and the energy they produce.
Where I live we have sunshine for about 300 days a year, since the climate is very pro-Mediterranean.
What kind of a solar panel will I need to use for this new 850 W PC I am planning to put up ?
In the shops here, the panels are from 80-90 W to 210-250 W.
Can anyone of these be of a help for My new PC, or there is something else I don't know ?

ANSWER:
Solar panels produce DC current, not the AC current your computer plugs into. To convert from DC to AC you need an inverter. The inverter takes the DC and outputs AC. For the inverter to run properly it needs a certain incoming voltage and amperage, which would be obtained by daisychaining the panels in a certain manner based on the output voltage and current of the cells.In all of this, due to losses, you only have roughly 65-75% of the output from the nameplate wattage on the cells. And that is when the cells are producing at full capacity, which they generally will not be. You will only get full capacity during the noon time high sun. Any other time of the day when the sun is shining it will only be some fraction of the nameplate rating.
Of course, this means you can't run your computer at night and need to oversize your array to handle the less-than ideal sun.
Even in the ideal world that assumes you could pull it all off, installed cost is - per installed watt. You'll need at least 1000W, so you have -10k in your solar system at the ideal case.
Edit:
To the comments about the computer using DC. Of course, but the technology already exists for doing conversion from DC to AC and providing a conditioned power signal. That is the key, really. Yea, you could Frankenstein some DC wiring to the mobo, but you'll need to engineer a way to condition the power so that the computer isn't fried the first instant you try to power-on.My point in even answering this question was to indicate how ludicrous it is. Really, if the guy has the money for the capital investment and wants to off-set his power usage, he should get a proper solar install wired to the home's electrical system. If he creates more than he uses, it goes back to the grid for credit. Use more than you produce, and you just supplement from the grid. Now you have the benefit of solar power to decrease your usage off the grid, but the computer isn't going to shut down every time the sun goes behind a cloud.
