MIT Works to Power Computers With Spinach
"Eat your spinach," Mom used to say. "It will make your muscles grow, power your laptop and recharge your cell phone... " OK. So nobody's Mom said those last two things. But researchers at the Massachusetts Institute of Technology say they have used spinach to harness a plant's ability to convert sunlight into energy for the first time, creating a device that may one day power laptops, mobile phones and more.
Photosynthesis, the process by which plants use light beams for energy rather than eating food like animals, has been known to scientists for decades.
But attempts to combine the organic with the electronic had always failed: Isolate the photosynthetic proteins that capture the energy from sunlight, and they die. Inject the water and salt needed to keep the proteins alive, and the electronic equipment is destroyed.
