3. Rechargeable Batteries It might be a bit disturbing to inject your urine into NoPoPo rechargeable batteries via a pipette, but you'll get over it once you realize that charges can be stored for 10 years and used in devices like this mini lantern/flashlight combo. Pee-injected AA batteries not powerful enough for you? The MetalCell is a portable power pack that uses stored number one and can keep a laptop charged up for more than four hours. [Source]

4. Mood Lighting Philips, always on the cutting edge for more energy efficient lighting solutions has an idea that involves storing bioluminescent bacteria in hand-blown glass cells. Not crazy at all, right? This is where it gets nuts. Philips wants to feed the contained bacteria methane gas harvested from human waste to illuminate nightclubs, movie theaters aisles and roads at night. Would you feel any less relaxed if you knew your mood lighting was being powered by dung-eating bacteria? [Source]

1. Poop-powered Toilet Bike Toto's "Bike Neo" is not your typical motorcycle. Is a regular motorcycle powered by pooping into its tank? Does a regular bike know how to talk, blast out fortunes, stock quotes, weather forecasts and play music? Is a regular motorcycle shaped like a toilet? Because the Bike Neo is all of that, and it's crazy. [Source]

2. A Power Source In Space Who knew that the poo-eating bacteria known as Shewanella MR-1 could turn feces into hydrogen that can then be used in fuel cells? Not us regular folk. Launched last year in a United Nations satellite called UNESCOSat, researchers will spend the next five years watching to see if the onboard bacteria will eat astronaut feces up in zero gravity as they do on Earth. If successful, our comrades up in space could have a new source of power. Those moon colonies aren't going to power themselves, ya know. [Source]

5. Thirst-quenching Drinks As disgusting as it may sound, the H2O is a prototype design that would make it easy to turn your secreted liquids into drinkable water. Simply pee into the container, cap it up, squeeze it between your legs and then open the spout and drink! If Gatorade-type drinks are more of your thing, you can try the Forward Osmosis Bag (FOB) that'll convert pee into delicious electrolyte-filled sports drinks with nary any effort. FOB's were sent up to the Space Shuttle Atlantis for "testing." Can't go wrong with the FOB if the guys on the ISS mix their own Pee-torade and aren't dying. [Source]

6. Rocket Fuel You're about to learn something that'll win you bets during drinks with your friends. When an Anammox amoeba ingests ammonia (which is found in urine), it can covert that into hydrazine. What's hydrazine? Why, it's a type of rocket fuel, my friend — the kind that NASA used to put into space shuttles to send astronauts up into space. Now go out there and win some bets! [Source]

7. Automobiles You'd think a car powered by human excrement would be crap (pun intended), wouldn't you? Not true. Bristol-based sustainable energy firm GENeco proved with this sporty Volkswagen Beetle that a car powered by 70 households' worth of poo can be just as green as an electric car. This special Beetle can go 10,000 miles on all of that waste and hit top speeds of 114 miles per hour before it craps (sorry!) out. [Source]

8. Home Heating While everybody is busy figuring out how to install solar panels and paint their roofs with thermal paint, 200 homes in the U.K. are enjoying houses heated by doo-doo. We kid you not. Using the same method as Philip's bioluminescent concept, bacteria eat up human sewage and convert it into methane gas, which is then either turned into electricity or purified for heating systems. Sludge power! [Source] Image via here.
