"It may sound surprising, but when times are tough and there is no other food
available, some soil bacteria can consume traces of hydrogen in the air as an
energy source.

In fact, bacteria remove a staggering 70 million tonnes of hydrogen yearly from
the atmosphere, a process that literally shapes the composition of the air we

We have isolated an enzyme that enables some bacteria to consume hydrogen and
extract energy from it, and found it can produce an electric current directly
when exposed to even minute amounts of hydrogen.

As we report in a new paper in Nature, the enzyme may have considerable
potential to power small, sustainable air-powered devices in future."
