Quote:I remember watching some program on the discovery channel about 4-5 years ago. The guy was talking about the technology they have today only harvest about 2-5% of the energy the sun produces, they where researching materials trying to find the right element or combination of materials that could harvest 30-35% of solar energy, he said when they find that element or even create the element that's when the switch to solar will be done.

 

Just always stuck in my head, don't know why......
