American scientists have learned to generate electricity using a unique bacterium.
Researchers at the University of Massachusetts have discovered a way to generate electricity using the Geobacter bacteria.
To do this, they created a device called Air-gen.
A unique bacterium is able to receive energy in the absence of access to oxygen. Scientists have known about these properties since the 1980s when the bacterium was discovered in the United States.
However, scientists have now found that Geobacter can also create protein threads of nanometer thickness. If such a thread is placed between the electrodes, then, as the experimenters found out, an electric current flows spontaneously through it.
“We literally produce electricity from the air”, says electrical engineer Jun Yao from the University of Massachusetts at Amherst. “Air-gen generates clean energy 24 hours a day.”
