Look for one of these! Japanese plumbing company Toto has brought to market a motorcycle that runs on human waste. The waste sits under the driver's seat and is converted into a biofuel that powers the three-wheeled bike. Y'all gross as hell, Japan. Y'all gross. It features a toilet seat for a, well, seat. But it's not like you're actually excreting the bikes' fuel as you ride around, it's a PURELY DECORATIVE toilet seat.
