On space missions urine is already recycled, and on the earth, there are already systems that transform human urine back into drinking water. It is a fairly obvious way to recycle human waste. A creative method is currently being tested as the United Kingdom, where there are buses that use human waste as fuel. Scientists at the University of the West of England have been busy as you can still continue to use human urine. The result is a toilet that can turn urine into electrical energy.
How to make energy from urine?
In a moment of humor, scientists have established the prototype before a student bar , However, the project objectives serious to enjoy as drunken students. The electricity that produces small outhouse is used to illuminate the same. Possible applications for such a system would, for example, refugee camps, which rarely have electricity. There they could increase the overall security.
But how does it work? The outhouse is equipped with microbial fuel cell (MFC from the English “microbial fuel cells”), based on a microbial metabolism. The bacteria in the MFC cells extract nutrients from the urine while producing electricity as a byproduct.
“The MFC is in effect a system Which taps a portion of did biochemical energy used for microbial growth, Converts and did Directly into electricity-what we are calling urine or pee-tricity power. This technology is about as green as it gets, as we do not need to utilize fossil fuels and we are Effectively using a waste product thatwill be in plentiful supply, “ explains the project Ioannis Ieropoulos in a press release.
In addition, the microbial fuel cells are extremely low. A single unit costs in production about 1.40 €. An outhouse on the nature of the prototype costs in about 850 €. The prototype was designed along the lines of portable toilet that uses the Oxfam in refugee camps. If the test phase is successful with the prototype, similar units can be hopefully used soon where they are really needed.
The generation of energy by recycling is an issue that is for the people of crucial importance, why there are countless projects in this area. Prominent examples are the “Energy Tower” in Denmark or the production of biofuel from algae.
