The Toliet Bike Neo gives newfound use to animal droppings. Livestock wastes are the actual power source for the motorcycle. A great way around our dependency of fossil fuels. 

After three years of research, the Neo recently made its official debut in Japan. Engineers developed a way to covert wastes and water to methane gas and the the gas is converted into bio-gas. I wonder if the exhaust leaves a scent while in motion. For one month the Neo was used around Japan and travelled for a total of 870 miles. No need to hold your nose just yet, developer TOTO have no plans to mass produce the bike, it's just a fancy science experiment I guess.
