The Bill and Melinda Gates held an interesting event on 14 August, in which there were different types of toilets / Commodes. The idea was to create a system to dispose of human fecal material without using water or electricity and a septic system.
Students of the University of Colorado took home $ 780,000 dollars for his idea: a system that uses solar energy to convert human waste into a kind of biological biochar or charcoal.
How does this system? We do not know, given the circumstances we do not care much, but certainly is a brilliant idea that will probably leave early conceptual stage.
