Stirling Engine
How cool! I found my old model stirling engine (similar to this one) while rummaging through the basement. It even works with a hot cup of tea! Read more about this cool gadget and the underlying interesting principle here on wikipedia.

This is a highly interesting (german language) video about the function of the torque converter that drives every car with an automatic transmission. I didn’t know that before and learned a lot!
