A New Job For Dirt?
It turns out wind power, solar power and lunar power are not the only possible renewable energy sources for our future. Dirt power might be next. There are already plans for use of it in places of Africa that are off-grid.
We first heard of dirt power back in May of 2008. Six Harvard University students (a.k.a known as Lebônê) won a $200,000 grant from World Bank at the Lighting Africa 2008 event in Accra, Ghana for inventing a way to turn soil into electricity using microbial fuel cells.
