Why not develop a way to harvest the energy generated during photosynthesis to create a greener form of energy and a new generation of solar panels? During photosynthesis, light is turned into chemical energy by the splitting of water atoms into hydrogen and oxygen. The electrons are then used to create sugars to feed the plant. The idea is to find a way to collect those electrons before they are turned to sugars. The technique will involve interrupting the paths along which...
