Converting human waste into useable fuel is not a breakthrough idea. In fact, it's been done for years. However, here's a new twist: in the capital city of Ghana, Accra, Colombia University professor Kartik Chandran will make biodiesel and methane from human waste using his self-developed "Next-Generation Urban Sanitation Facility" (not pictured).

Chandran's idea is rather simple: provide local African communities with access to affordable fuels while eliminating the potentially negative public health impact of improperly treated waste.

The Columbia University professor's efforts have not gone unnoticed. Recently, Chandran was awarded a $1.5 million grant from the Bill & Melinda Gates Foundation. Though $1.5 million probably ain't enough, it's a start.
