Bacteria discovered that exist on pure energy (“eating” electrons)

Microbiologists based in California have discovered bacteria that survive by eating pure electrons rather than food, bringing an entirely new method of existence to awareness and raising questions about possibilities for alien life.

The ‘electric bacteria’ – as they have been dubbed by the team that discovered them – take energy from rocks and metal by feasting directly on their electrons. The hair-like filaments the bacteria produce carry electrons between the cells and their environment.
