Episode 553 - E.coli to the rescue and boosting geothermal power

Lagrange Point

E.coli is one of the most studied and versatile bacteria, so how can we make it work for us? Bacteria's ability to generate electricity is well known, but often requires complex conditions. How can we use E.Coli to generate electricity without a complicated setup? Geothermal systems seem to promise unlimited power but sometimes a cold water 'short circuit' ruins the plan. How do you carefully control the efficiency of geothermal power in the extreme temperatures and pressures of the earth?
