Saving waste energy

Alphabet energy (Based in California, USA) have created a large scale thermoelectric generator – the E1 which turns waste heat into electricity. It is designed to be used in remote mining locations to reduce the amount of waste energy – in a typical 1MW plant emission will be cut by 2.5%.

Alphabet Energy's E1 generator.

The E1 uses the mineral tetrahedrite to turn heat into electrical charge – tetrahedrite has the rare property of being a good electrical conductor and a poor thermal conductor meaning a current can pass through it when it’s heated.

Scaled up versions can be used for larger power stations where as scaled down versions can have a variety of application including car exhausts where they can reduce green house gas emissions by 5% – given the number of vehicles this could have a massive impact.
