Three of the four talented girls are only 14 years old this year. They are Duro-Aina Adebola, Akendele Abiola and France. Faleke Oluwatoyin and one of the 15-year-old Bello Eniola. They presented their “human urine generators†at the recent “African Manufacturers Exhibition†held in Lagos, Nigeria.
The website of the organizer "African Manufacturers Exhibition" blog introduces the result of this invention: "The urine is poured into the electrolytic cell where the urine is decomposed into nitrogen, water and hydrogen. Then the hydrogen is passed through the water filter. Purification is carried out and pushed into a gas cylinder in which hydrogen is passed through the borax in order to remove the mixed moisture components of the hydrogen. These purified hydrogen are then sent to the generator. urine can produce about 6 hours power supply. "
In order to reduce the risk of explosion caused by hydrogen, the development team used a one-way valve, but some people think that this equipment may still have certain risks after doing so.
According to Forbes magazine, the demand for power generation equipment in Africa is much larger than that of developed regions like the United States. Although Lagos is the center of urbanization in Nigeria and the most affluent city in the country, there will still be power outages from time to time.
Although the idea of ​​such a power generation device is generally innovative, the National Broadcasting Corporation (NBC) reported in the report that the use of human urine as a source of power generation may not be suitable for large-scale deployment.
In his report, NBC quoted Gerardine Botte, the chemical engineer at the University of Ohio, the original proponent of the principle of urine power generation: "This is a small invention on campus, so don't take it seriously." Ok," Bout suggested that these students "work with engineers to understand the technology and its rational application," because Bout invented the technology's original intent to "making the wastewater treatment process more energy efficient."
But no matter what, the little inventions made by these children have at least been judged by scientists, which is a good thing anyway.
