article_snippet: The technology uses microbial fuel stacks in the toilets, which feed on urine, creating biochemical energy  that can be turned into electricity.
article_snippet: The units contain bacteria that breaks down the chemicals in urine, in the process releasing energy in the form of electricity which is stored on a capacitor within a fuel cell. '
article_snippet: The microbial fuel cells (MFC) work by employing live microbes which feed on urine for The microbial fuel cells (MFC) own growth and maintenance,' explained Professor Ioannis  Ieropoulos. '
article_snippet: The MFC is, in effect, a system which taps a portion of that biochemical energy. '
article_snippet: The research team is led by Professor Ioannis Ieropoulos, of the Bristol Robotics Laboratory at UWE Bristol, who is an expert at harnessing power from unusual sources using microbial fuel cells. '
article_snippet: We have already proved that this way of generating electricity works,' Professor Ioannis  Ieropoulos said. '
article_snippet: Work by the Bristol BioEnergy Centre hit the headlines in 2013 when The research team demonstrated that electricity generated by microbial fuel cell stacks could power a mobile phone. '
article_snippet: The microbial fuel cells work by employing live microbes which feed on urine for The microbial fuel cells own growth and maintenance. '
article_snippet: The microbial fuel cell is in effect a system which taps a portion of that biochemical energy used for microbial growth, and converts that directly into electricity - what we are calling urine-tricity or pee power. '
article_snippet: Prof Ieropoulos added: 'One microbial fuel cell costs about £1 ($1.5) to make, and we think that a small unit like the demo we have mocked up for this experiment could cost as little as £600 ($900) to set up, which is a significant bonus as This technology is in theory everlasting.'
