Self-powered useful devices, or SPUDs are the latest craze in the scientific world. They are not new but modern technology and science is finding a way to make these amazing bacteria pools to be useful to humans.

Is this exploitation or another smart use of natural surroundings? Only time will tell. I am sure we will find a way to do both.

What is a SPUD? They are bacteria, but unlike any other life on Earth, these extraordinary bacteria use energy in its purest form – they eat and breathe electrons – and they are everywhere.

There 2 categorized bacteria’s of this sort ( Shewanella and Geobacter) but scientists are finding more.

How do they find them? Simple yet effective, they stick an electric probe into the dirt and send voltage down the line.

The phrase “build it and they will come” applies to these little bright glowing critters.

What could they be good for? Besides being in the cycle of life they may be able to : Electric bacteria could have practical uses here on Earth, however, such as creating biomachines that do useful things like clean up sewage or contaminated groundwater while drawing their own power from their surroundings. Nealson calls them self-powered useful devices, or SPUDs.

Practicality aside, another exciting prospect is to use electric bacteria to probe fundamental questions about life, such as what is the bare minimum of energy needed to maintain life.
