The Candela Amplifier is a high quality demonstration of thermoelectric generation. Thermoelectric generators are a form of alternative energy generation that contain no moving parts. This example uses the waste heat from a small flame to generate electricity and emit useful light from a bright LED, thus "amplifying" the light output from the flame. This shows the concept of a thermopile (e.g. Peltier or Seebeck effect) to generate electric current from a thermal input.
