"Scientists at Stanford have just discovered the greenest source of energy yet — harvesting electricity directly from plants! They’ve successfully generated energy from photosynthetic processes in algae by tapping straight into currents of electrons generated at the cellular level. We know that cars can run on bio-fuel made from algae, but imagine if our power grid could run on pond water in its natural state. No refinement is necessary – all you need is a pool of water, a bunch of the green stuff and a high-tech gold electrode. Best of all, the only by-products are protons and oxygen!"
