What's really going on here? The energy from sunlight is harvested by the bacteria to split water into hydrogen and oxygen. So, essentially, this is a form of solar energy. Is it realistic to expect this source of solar energy to compete with solar panels, which provide direct electric current, and which do not suffer from the inate energetic inefficiencies (I'm talking metabolic pathways here, not current efficiency levels) of biological processes? I doubt it, especially considering the storage problems of hydrogen. I don't think this discovery will revolutionize the hydrogen industry, much less the world energy industry. It's fun to go nuts over these reports, and dream of a care-free life, but please, let's think about the overall thermodynamics of the situation.
