Thermomechanical generator
A thermomechanical generator is a device that can make electricity by using heat.
Think of it like when you're playing with a toy car that runs on batteries. When the batteries run out, the car stops moving. But imagine if you could use heat to make the car move again and the heat would make electricity to power the car. That's what a thermomechanical generator does.
The generator has two parts: a hot side and a cold side. The hot side gets really hot and the cold side stays cool. When there's a big temperature difference between the hot and cold sides, it creates something called a thermal gradient. The thermal gradient is like a push or a force that can make things move.
Inside the generator, there's a metal that can bend or flex when it gets hot. When it bends, it makes contact with another metal that's connected to a wire. The movement of the metal is like a switch that turns on the electricity and the wire can carry that electricity to power something else, like a toy car.
So when you heat up one side of the generator and keep the other side cool, it can generate electricity by using that thermal gradient to make the metal move and create a flow of electricity.
Overall, a thermomechanical generator is a cool way to use heat to make electricity without needing any kind of fuel or batteries.
