Photovoltaic Cell from Plant Proteins
TheSync writes "FuturePundit has a story about work at MIT to develop a photovoltaic cell from spinach chloroplast proteins to generate electricity. These cells convert 12% of the light energy into electricity, and researchers hope to reach 20% efficiency, better than commercial silicon solar cells."
I've got a charcoal grill built entirely out of hamburger and frankfurters. To my knowledge it's the first edible grill that cooks itself.
