This self-contained and waterless toilet is called the EcoJohn Sr Toilet. Quite simply, it burns the crap you normally flush, into white ash. It operates just like a regular toilet, except that water doesn’t take away your waste. Just close the lid and the waste is whisked away like South Park’s Mr. hankey the x mas poo on Christmas eve. It’s final destination is a burn chamber where it is cremated. A small bit of smoke is belched out and filtered through a catalytic converter before hitting the air.
There is some water involved, just minimal. The toilet is equipped with a small reservoir that holds about a quart of water. Press a special rinse button, and it’s easy to keep the bowl and auger clean. It’s the perfect water saving device, though I’m not sure how I would feel about having a chimney on my toilet.
