Urine Powered Generator

Girl Power! Four young Nigerian girls have invented a generator that runs on urine.

The invention was first displayed in Lagos, November, 2012, at the 4th annual Maker Faire, a pan-African innovation fair. Three 14-year-olds, Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin and 15-year-old Bello Eniola are the inventors.

How The Urine Powered Generator Works

The system separates urine into nitrogen, water and hydrogen.

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.

The girls say that one liter of urine gives six hours of electricity. But they do not specify exactly how much electricity is produced; enough to run a 60-watt light bulb, or a fridge and computer for six hours? We excitedly await more news…

Throughout the mechanism there are one-way valves for safety. Without the safety valves, this generator could be explosive, as hydrogen is flammable. ;-[

  1. hi

    my name is chandrasekhar,pursing masters degree in embedded systems at guntur,a.p,india.i am interested to know details about your details.if you wish to share about your project you can say details about your project



  2. Waoo great job girl but I have a question did u make an change in the generator parts for it to run on hydrogen fuel

  3. My USA friend, scientist Harry Braun, supports getting rid of dependence on oil, petrol, nuclear, and other poisonous polluting fuels, and converting the world to run on clean hydrogen fuel produced by the electrolysis of water with cheap solar, water-current, or wind-generated electricity. See https://PhoenixProjectFoundation.US to connect to a sustainable future. Nigerian sisters, please give links to your project details or contact information.

  4. We get HHO gas from hidrolisis proces and we are so interested in your sistem because here in Mexico have a lot of problems to get chip energy, please send some info about your proces.


  5. I am just wondering how much electricity is used for the conversion of urea to hydrogen. Does this system produce more then it spends?

  6. Well done to this team of inventors, it is a development that will be increasingly more important in the future. as the days of cheap and abundant fade into history. Even in England, where I live, supplies from external generators are uncertain in remote areas.

    This well, at least, will never run dry

  7. Come on, who will believe that! It it were true, you would have big companies jump on this and it would make the local news in a flash…urine is 99% water. So you could do the same with water.

  8. JAKE- No way. The process to do this with water was developed many years ago. Designed to power motor vehicles. The patent to power engines with H2o was bought up and shelved many years ago by the petroleum industry. Imagine where BP would be if we could use water to power everything with no by product of any pollutants.

  9. Congratulations on your success.

    I am pleased to inform you that we are trying to implement your idea in Bangalore(INDIA).

    It will be grateful of you if you can share the procedure

    and forward the project report to my mail id so that we can study it.


  10. wow

    what will the waste product be like? how bad/good can the CO4 be? And since fuel uses alternator, and diesel injector, WHAT WILL URINE USE?????

  11. Pah! Pee power generation has been around for a while. Check out the youtube videos of the guys peeing over the bridge on the train power lines below, that’s a lot of electricity generated right there. Though you will have a hard time finding anyone left alive afterwards….

  12. Congratulation!

    I have been working with hho. for one year. I’m looking for a way to reduce the amount of electricity used to convert water into hydrogen Gas.

    If you do not mind sharing the schematic details fo the project, please send me the info that would allowing me to replicate your system. If your system works fine, it will help many 14 year-old students like you in under developed countries such as other parts of Africa that do not have electricity.

  13. hii i am intersted to know about this .. can u please tell me that which electrodes are used in that electrolytic cell and which type of gas cylinder is used and how much pressure is needed in the gas cylinder and the total process please .. it will be helpful to my studies . soo please help me

  14. can u please tell me that which electrodes are used in that electrolytic cell and which type of gas cylinder is used and how much pressure is needed in the gas cylinder , and how hydrogen will be store ,and the total process please

  15. Actually this idea also came in my mind and I always want to do for this but now it gives me a clarity. Thanks and also provide me the whole procedure if you can then please help me in this topic.

    • Ibam interested in doing business with you so how much will it cost me to change my generator to a urine powered plant ?

  16. Hi I am writing to you prom India and I am interested to buy that generator if it is actually working.I will place regular orders if you share more details.

    Warm Regards

    Vish Berry




  17. I would wonder what are the maintenance costs of this contraption. Does the Borax, the filter need changing ? How often ? What is the final cost of the KW once everything factored in ?
