If all seven billion of us drove around in poop-powered toiletcycles, how much bad weather could we prevent?

This Poop-Powered Toiletcycle Is Touring Japan

The Toilet Bike Neo will be conducting its roughly 500 mile trip from Kyushu to Tokyo powered entirely by the on-board biogas digester. Biogas systems use an anaerobic bacteria system to convert dead organic matter into a usable fuel primarily made of methane. This system obtains its fuel from the rider—directly from the rider, if you get what I mean. It runs on the rider's poop—he just sits there, unloads, and rides off (hopefully with a step involving pants at some point as well). The system is reportedly efficient enough that it could run indefinitely were the rider sufficiently well fed.

The reason for the tour is to promote Toto's efforts to reduce its CO2 emissions by 50 percent in the next six years.
