Because we love toys, expecially those with some sort of alternative energy theme, we have collects some here that don't exactly fit into our other categories. So we fit them into their own special "Other" category.
Here we have Stirling Engines that run on any external heat source, such as solar power, the heat from a wood stove, or even the heat from your hand.


We also have radios that require no power at all. Crystal radios get their power directly from the radio waves that carry the information.


But for those who need more exercise, we also have crank-up radios (although some of them allow you to cheat by using solar cells).

Or, how about a toy car that runs on power from its own fuel cell?

And, just for fun, we have light sticks that glow in the dark like fireflies from their own internal chemical power.
