OK.
So this is a great news for green energy.
Hydrogen is the most abundant element on out planet. Scientists have discovered a bacterial enzyme that converts hydrogen into electricity, and they think it could be used to create a new, clean source of energy literally from thin air. Name of the enzyme is Huc, it is produced by bacterium Mycobacterium smegmatis to draw energy from atmospheric hydrogen, enabling it to survive in extreme, nutrient-poor environments.
