Designer Space Slime Fuels Electricity

 Scientists have pinpointed two types of stratospheric bacteria and transformed it into a slimy film that doubles the efficiency of fuel cells that run on microbes. It could mean power for underdeveloped locales that currently don’t have electricity.Scientists surveyed 75 bacteria from the stratosphere—the second layer of the earth’s atmosphere about six to 30 miles above the earth’s surface—to find the most efficient bacteria for generating power. Their bacteria pageant led them to two super-efficient bacteria: B. stratospheric, and B. altitudinal.

Besides have really fun names, B. stratospheric, and B. altitudinal fell from the atmosphere into the Wear Estuary in Country Durham, where scientists from Newcastle University in the United Kingdom collected them. They then used the bacteria to create a designer slime and build the most efficient microbial fuel cell ever. It’s twice as fast as anything like it today: 200 watts per cubic meter versus 105 watts. That’s still not a huge amount of power, but it would be enough to cheaply generate electric lights and provide a power source to underdeveloped locations, according to the scientists, who are published their work in the American Chemical Society’s Journal of Environmental Science and Technology.
