Bacteria can generate energy and purify water

Nasa is testing electroactive bacteria for space exploration. The technology is also used to a water treatment system capable of purifying 6.600 gallons of water a day

The electroactive bacteria system is an efficient energy-generation method that offers zero waste. Technically speaking, the microbes feed on organic matter and spontaneously generate electricity by having contact with metal. In 2018, Nasa sent an experiment to orbit the Earth through the International Space Station to compare the performance in our planet and in space. There’s also a company using the bacteria for treating residual water. An ongoing method in Argentina, Denmark, Mexico, and Spain is capable of purifying 6.600 gallons of water a day without any external energy consumption.
