It sounds like a gag gift instead of serious science, but a new electrical farting machine could improve fuel cell technology by turning C02 in the atmosphere into methane.
The technique won't combat global warming directly, since both CO2 and methane are potent greenhouse gases, but it could help store alternative energies such as wind and solar more efficiently.
It works like this: giving small jolts of electricity to single-celled microorganisms known as archea prompts them to remove C02 from the air and turn it into methane, released as tiny "farts." The methane, in turn, can be used to power fuel cells or to store the electrical energy chemically until its needed.
Archea are older, and more primitive, than bacteria, lacking a nucleus and other cellular machinery.
methane-producing archea team up with termites to digest wood pulp. With other microorganisms, they help decompose organic matter. |
A device that can both improve fuel cell technology and entertain 12-year-old boys. That's what I call the modern biathlon.
All in all a very ingenious and creative way to use micro organisms for our benefit.
