How do thermoelectric generators work?

10 February 2012
Presented by Sarah Castor-Perry.

Huge amounts of energy are lost from power stations and cars as heat. But what if we could harness that heat and turn it into useful electricity? That's what thermoelectric generators or TEGs can help us do. In this Naked Science Scrapbook we find out how they exploit a temperature gradient to produce power and how they're already powering space exploration.
