Description
It's hard to believe, but this engine runs on just the heat from a cup of coffee!
Place the Heat Power Machine on a cup with something hot in it, wait half a minute, give it a little push and watch it spin.
Or put it in the palm of your hand and put an ice cube on top. If you're lucky, you can make it run on the heat of your hand!
That's how it works
VitenWahl's Heat Power Machine is a type of sterling motor. It works by pushing trapped air between a chamber where the air is heated and a chamber where the air is cooled.
The air closest to the bottom expands as it heats up, pushing the main piston upwards. As it approaches the top, the small piston pushes the cooled air back under the main piston. And then it starts all over again.
What can the Heat Power Machine be used for?
Impress friends or colleagues. Nothing else.
