Japan's best-known toilet maker on Wednesday unveiled a
"poop-powered" motorcycle that can travel as far as 300 kilometres
(180 miles) on a tank filled with animal waste.

Billed as the world's first waste-powered vehicle, the
three-wheeler has a toilet in place of a regular seat and huge
paper roll at the back.
But as a young female model climbed aboard for a test drive
Wednesday, toilet giant TOTO was quick to point out that she would
not supply the "gas".
"The biogas it uses as fuel is not made from human waste. It's
made from livestock waste and sewage," Kenji Fujita, a company
spokesman, told reporters in a Tokyo suburb.
"We hope to raise awareness among customers about our green
campaign through development of environmentally-friendly products
such as water-saving showerheads and water-saving toilets," Fujita
added.
The company -- which makes toilets equipped with an array of
features including heated seats, water jets with pressure and
temperature controls, and ambient background music -- has no plans
to commercialise the motorcycle.
