Green transportation is advancing by leaps and bounds. In just the past few months, we've seen a solar-powered airplane complete historic flights, self-driving vehicles hit the streets and cars make astounding achievements in fuel efficiency. However, for every big breakthrough there are scores of off-the-wall designs that are almost too out there to believe. Read on for seven of the weirdest, wackiest and most wonderfully creative green vehicles around.
1 / 7
It’s pretty obvious what makes this motorcycle different from any other: There’s a toilet where the seat should be! But, the "Toilet Bike Neo" isn’t designed to let you "go" while you go. This three-wheeled motorcycle actually runs on animal waste, which can propel this strange bike about 180 miles on one tank.
Still, the Neo is really more of a statement piece than a revolution in motorcycle design; it was made by Japanese toilet maker Toto to highlight its environmental efforts. We’re not sure what the company's line of water-saving shower heads might have to do with a poop-powered motorcycle, but this is definitely one of the weirdest vehicles we’ve ever seen. As for the throne, it’s not actually a working toilet -- at least, we don’t think it is.
