Renewable energyThe reason – the difficulty in creating large-scale installations.
Ieropulos invented a battery of 12 MFC, created on the basis of porous ceramics and grouped into three blocks of four parallel-connected elements. The system was connected to a low-power pump is run through a fuel cell urine at 250 microliters per minute. In an article published in the journal Journal of Physical Chemistry Chemical Physics (impact factor of more than 3.5, in national magazines this figure is less than 1, in Nature – 38) specifies that the raw materials “were collected from healthy individuals and mixed together before filling the in MFC ».
Instead of nuclear waste
By combining two well-known technologies for electricity, scientists have created the energy cell, capable of operating anywhere you have stocks of waste … →
Experiments have shown that in the absence of an electrical load creates stress urinary battery 3.25 volts, the power of 2.5 milliwatts. To accumulate such a small charge, the urine should chase through three times, then stored in the capacitors is enough power to supply the mobile phone. “The Battery of the microbial fuel cell provides enough power to send SMS, surf the internet and make short calls. Most energy demand calls, so we are working on how to charge phones for a long time, “- said Ieropulos.
In his experiments charged urine phone switched off after four minutes of conversation.
According to the inventors, their technology does not require expensive materials and has the potential for subsequent commercialization. Existing market ceramic cylinders, providing the basis for fuel cells cost about 50 cents, and serve a decade, the cost of the same elements themselves is about $ 1.7.
Scientists believe that the invention, the financing of which was conducted in part by the Bill and Melinda Gates Foundation, will be used in the manufacture of compact toilets and in third world countries – where people live far from the grid. “It’s the world’s first demonstration of the fact that the batteries of mobile phones can be charged from a fuel cell running on urine. Compared with other organic raw urine was an excellent material for direct production of electricity. This opens up many opportunities for waste management in remote areas, “- says the inventor.
