Oh, in case you were wondering how far some environmentalists will go to conserve water, allow me to introduce you to the EcoJohn.
It’s a toilet that uses no water.
Yes, instead of flushing the old fashioned way, you "close the lid and a large, screw-like auger turns and carries the waste to the burn chamber where the propane burner then bakes urine, feces and paper into ashes."
Uh huh, you read that right, it barbeques your poop.
Doesn’t exactly make me want to haul one along to my next party or event. Can you imagine? “Yes honey, I’m so thrilled your parents made it to the wedding. Now if you’ll excuse me, I need to take a dump and then have it set on fire. Everyone, try not to breathe for the next few minutes.”
