Urine Powered Generator Produces Electricity For 6 Hours on 1 Liter of Pee: Power Your Home With Waste

Imagine powering your home with waste bi-products. You could essentially power you home with pee. Adult human being produces 1-2 liters of urine per day. 1 liter is enough to power a small generator for 6 hours. How do we know this? A 14 year old girl and her friends from Nigeria, Africa created a system that separates the hydrogen and oxygen in urine, purifies the hydrogen and uses it to power a generator.

Forget gas, batteries

Urine-powered cars, homes and personal electronic devices could be available in six months with new technology developed by scientists from Ohio University.
Using a nickel-based electrode, the scientists can create large amounts of cheap hydrogen from urine that could be burned or used in fuel cells. "One cow can provide enough energy to supply hot water for 19 houses," said Gerardine Botte, a professor at Ohio University developing the technology. "Soldiers in the field could carry their own fuel."
Pee power is based on hydrogen, the most common element in the universe but one that has resisted efforts to produce, store, transport and use economically.
Storing pure hydrogen gas requires high pressure and low temperature. New nanomaterials with high surface areas can adsorb hydrogen, but have yet to be produced on a commercial scale.
Chemically binding hydrogen to other elements, like oxygen to create water, makes it easier to store and transport, but releasing the hydrogen when it's needed usually requires financially prohibitive amounts of electricity.

The system works like this:

• Urine is put into an electrolytic cell, which separates out the hydrogen.
• The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.
• The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
• This purified hydrogen gas is pushed into the generator.

Along the whole way there are one-way valves for security, but let’s be honest that this is something of an explosive device…
