Solar cells powered by plant proteins?

July 6, 2004 | Science | By: Mark VandeWettering

Nature ran an online article entitled: Could laptops run on spinach?: Solar cells turn over a new leaf. Curiously enough, I have been going over plant and animal metabolism with my son who is doing a semester of college biology, so I’ve been forced to review the chemical reactions that take place as part of the Calvin cycle, so I found the article interesting. The functioning of biological nano-machines can still teach us a great deal.
