solar cells aren't cost efficient yet. and it doesn't really matter about being in dessert, heat has nothing to do with the amount of sunlight the cells accumulate.

yeah, but there is always the sun -> energy.

The thing that will never exist. You put energy into it, and it gives you more energy back.

No, because a perpetual motion machine runs indefinitely without any additional input of energy once it's started.

Are you thinking of purpetual motion?

And since the energy is coming from an outside source (the sun), it would not be purpetual motion.

It would be 0% perpetual motion since 100% of the energy is coming from an outside source- the sun.

I thought it was like, you put energy into something, and more will come out.

The cost of collecting the energy isn't too bad with solar cells in the Sahara, but the cost of TRANSPORTING the energy to someplace USEFUL is dramatically high

But once there would be a perpetum mobile, all our power worries would be over, no?

At least only my posts are senseless compared to you.

The sun is not always available at a desert.
Deserts arent even at the equator if thats what your thinking, deserts exist because of weather patterns caused by the hadley cell.
You could get 24 hour sunlight at the poles for parts of the year, or if you put a satelite into orbit around the sun. You definately gonna need a long time before you get your energy back.

That post didn't make any sense either.

Again? Are you perpetually drunk or something?

Perpetual motion has nothing to do with solar cells. By definition perpetual motion is a mechanism that is 100 % energy efficient meaning no energy is lost to friction, resistance, etc.
Once you set the device in motion, it will stay in motion forever without ever needing any additional energy from something like a solar cell.

Only 8 minutes at the speed of light.

Uh, 8 minutes for light to reach the Earth.
To keep a satelite in orbit around the sun takes energy, so does moving a device from Pole to Pole to gather 24hr/day energy.
Just cause light reaches Earth in about 8 minutes does not mean you get the energy you put into the device back.

The electricity you get from solar energy is much less energy than the solar energy itself. Therefore it's not a fdsjoipfajmobile.

You sir, are an idiot.

Just because it's a desert does NOT mean the sun shines 100% of time. There is night in the desert, moron. Also, WTF is perpetum(SIC) mobile?'

Conversion of energy from one source to another has NOTHING to do w/ perpetual motion. All you're suggesting (even IF we could get 24hr sunlight) is that the solar cells run steady-state indefinitely, such as ALL power generators do. The fact that sunlight instead of natural gas, coal, nuclear material is used is irrelevant.

Also, solar cells are NOWHERE near 100% efficient, in fact, they are so inefficient that even if run 24hrs a day for 30years, they would not output more energy than was necessary to make them.

STOP POSTING IGNORANT DRIVEL.

Sorry. I thought you were talking about getting the energy you collected at the sun "back" to earth, not recouping invested energy.
