Dirt-Powered ‘Forever’ Fuel Cell

Researchers at Northwestern University in the US have created a fuel cell that harvests energy from microbes living in soil so that it can potentially last forever (or as long as there are soil microbes). 

Why? 

As Bill Yen (who led the research) suggests, the value may lie in its ability to supply power to IoT devices and other devices in wild areas where solar panels may not work well and where having to replace batteries may be challenging.
