Spinach May Soon Power Mobile Devices
For the first time, MIT researchers have incorporated a plant's ability to convert sunlight to energy into a solid-state electronic “spinach sandwich” device that may one day power laptops and cell phones, reports PhysOrg. "Plants’ ability to generate energy has been optimized by evolution, so a spinach plant is extremely efficient, churning out a lot of energy relative to its size and weight. But combining biological and non-biological materials in one device has stymied researchers in the past. Biological materials need water and salt to survive—both are deadly for electronics."
