MIT uses spinach to power computers.
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.
At the heart of the device is a protein complex dubbed Photosystem I (PSI). Derived from spinach chloroplasts, PSI is 10 to 20 nanometers wide.
A 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.
