actually ...

Bearing no actual resemblence to its name. it is an artificial leaf, made of silicon electronics and other components, provides the same reaction to sun and water that an actual leaf would by converting it into energy. In theory one of these leaves that MIT researchers have designed submerged in a gallon of water and left out in the sun, could possibly power the common house for one day. And to my understanding its fairly cheap production cost wise at least. However we could see these mass marketed fairly soon!!
