cleantechnica.com — Traditional solar cells only use up to 20% of the visible light they collect, and more efficient solar cells are too expensive for mass production. Now researchers at the US Department of Energy?s Idaho Laboratory have figured out a way to capture solar energy on the cheap: plastic sheets filled with billions of nanoantennas.

Actually, there's enough uranium in the Earth's crust to support human civilization for longer than the Sun's expected lifetime.<a class="user" href="http://www-formal.stanford.edu/jmc/progress/cohen.html">http://www-formal.stanford.edu/jmc/progress/cohen. ...</a>

The fuel is a stream of photons. The problem is extending the drive shaft outside the engine block.

"Traditional solar cells only use up to 20% of the visible light they collect"This one does not collect any.."Of course, there is still plenty of research that needs to be done before nanoantennas can go into production—in fact, scientists still don’t know how to convert energy from the devices into electricity."Oh this one does not even make electricity...

Only dugg because it said it may be able to charge my iPod which is always a plus. Those iPhones don't last to long...
