We're always relearning from nature

The processes we use to obtain fuel, from pumping fossil fuels up from beneath the ocean to harvesting crops to turn into ethanol, create many environmental and practical concerns. These types of fuel work fine with the current generation of cars, but hydrogen has sometimes been touted as the fuel of the future. A publication in Nature Nanotechnology describes how researchers have found a way to use the photosynthetic machinery of a bacteria to produce the hydrogen equivalent of up to 79 gallons of gas per-acre, per-day. Their technique involved capturing the electrons produced during photosynthesis and binding them to some strategically placed protons.
