An artificial leaf and a gallon of water could generate enough energy to power your house for a day. The artificial leaf has been a target of solar research for years - an object that creates fuel sources out of sunlight, mimicking photosynthesis. But this solar energy breakthrough has always been thwarted by the need for rare components... until now.
New research out of MIT has created an artificial leaf that's not only cheap to build, but resilient too. The leaf is like a thinner version of a playing card in size.
