Cast your eyes upon Virginia Gardiner's LooWatt, a toilet made out of poop. The waterless toilet collects solid waste which is deposited into a container lined with 'a carbon impregnated biodegradable film' made of starch. When the container is full, the poop is harvested from the toilet and taken to an anaerobic digester (a poop eater) that captures the resultant methane gas which then can be used as a fuel source. That, ladies and gentlemen, is TRUE waste management.
Watch this video of Virginia explaining the system and why it just might change the bathrooms of the future. And to read more about the projects, complete with 'poop' jokes, visit Greenopolis.
