Scientists studying a cousin of the bacteria responsible for tuberculosis and leprosy have discovered an 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.
The enzyme, which has been named Huc, is used by the bacterium Mycobacterium smegmatis to draw energy from atmospheric hydrogen, enabling it to survive in extreme, nutrient-poor environments.
Now, by extracting and studying the enzyme, the res...
