It is developing a battery which can generate enough energy to power a household lamp or cell phone from waste materials such as soil and manure. The group is made up of former classmates from Harvard University has carried out field research in Tanzania.

Developers hope households will be able to build a one-off battery for less than 15 US dollars when the technology develops.
