  1. And more interesting to me is Peltier junctions. They work on temperature differential. But they generate electric current when the differential is right. And the upshot - there are a number of spacecraft that are on Mars for example that use Peltier junctions to take the heat energy from decaying radioactive material to power them. And if you think Infrared is cool I suggest UV. Shine it on objects and watch what happens. For instance your state ID, or paper money.

  2. Light pressure is also known as photon pressure
