In an ideal energy future, man-made solar cells would mimic much of the functionality of efficient plant life.   Currently solar cell technology is expensive and a maintenance headache but Purdue researchers are working a new type of solar cell that uses carbon nanotubes and DNA to come closer to plant life that can be durable enough for commercials use,

Their design exploits the unusual electrical properties of structures called single-wall carbon nanotubes, using them as "molecular wires in light harvesting cells," said  
Jong Hyun Choi, an assistant professor of mechanical engineering in the Birck Nanotechnology and Bindley Bioscience centers at Purdue's Discovery Park.
“Anyone who knows history, particularly the history of Europe, will, I think, recognize that the domination of education or of government by any one particular religious faith is never a happy arrangement for the people.”

“Will people ever be wise enough to refuse to follow bad leaders or to take away the freedom of other people?”
