According to the New Scientist, researchers at the University of the West of England in Bristol have developed a microbial fuel cell about the size of a mobile phone that could be powered by organic household waste.
The bacteria-driven cell, which would cost about $15, directly converts biochemical energy into electricity. It uses E. coli bacteria to break down carbohydrates and release hydrogen atoms.
The organic battery can produce eight times as much energy as other microbial fuel cells.
