researchers at psu, led by bruce logan, have designed a process to generate hydrogen from organic materials/waste.
the bioelectrochemically assisted microbial reactor, dubbed beamr, uses bacteria to break down biodegradable organic material. adding a small jolt of energy to the system causes hydrogen gas to bubble up to the surface. the entire process generated 288 percent more energy than the electricity required to produce the reaction. read more. watch a video.
