Japanese toilet manufacturer TOTO has created a motorcycle that runs entirely on biogas, in this case provided completely by the rider.
Perched upon a custom TOTO toilet-saddle, the user can fill the bike’s tank simply by emptying their own.
Being as the bike runs entirely on human waste, it could theoretically run indefinitely so long as you have to “go” enough.
Far from just a concept, the TOTO toilet bike will embark on a month long tour of Japan to prove that the technology works.
Whether or not biogas will be a viable alternative to fossil fuels remains to be seen, but there is absolutely no way you can call this vehicle “green”!
