Are there any other viable power sources available to us other than electromagnetic induction and photovoltaic technology?

When I make a lost of every source of power generation I can think of, everything comes down to either photovoltaic technology, or spinning a turbine which causes electromagnetic induction. Do we have any other way of powering our homes?

Fuel cells and thermoelectric generators are two less known ways. Fuel cells generate electricity through reacting oxygen with a fuel, often hydrogen, and have no moving parts similar to a photovoltaic cell. Thermoelectric generators use a strange property of metals called the seebeck effect, where two different metals at different temperatures connected at two points will cause a current to flow though them. 

Fuel cells are really only used for energy storage, because we don’t have an easy source of hydrogen without electrolyzing water, which takes energy. Thermoelectric generators aren’t very efficient, so we don’t use them often either. Though, in space they’re pretty handy because you can put radioactive plutonium pellets in a chamber which heats it up, and the outlet side can be cooled by radiating its heat to space, effectively giving you a constant power source for many years.
