Sharp solar cells can reach 60 percent efficiency
 

http://cdn.slashgear.com/wp-content/...ls-600x307.jpgSolar power is perhaps the most well-k**wn alternative source for power, but because of cost and the puzzles of physics itself, it is still quite far from becoming a completely sustainable and practical replacement.

The main … Continue readinghttp://feeds.feedburner.com/~r/slashgear/~4/wXK7xFWRnS4
