They have a spiral spring,similar to a wind-up clock, and when released it drives a small gear, which in turn drives a larger gear, giving the wheels a suitible turning speed.
no you did not wind up your car in the 1900s
Wind-up cars work by storing potential energy in a spring mechanism when the car is wound up. When released, the spring unwinds and transfers this energy to the wheels, propelling the car forward. The key mechanisms involved in their operation are the spring mechanism for storing energy, gears to transfer the energy to the wheels, and wheels for movement.
A wind-up car works by winding a key or pulling a string to store potential energy in a spring. When released, the spring unwinds and transfers energy to gears that turn the wheels, propelling the car forward. The key components involved in its operation are the spring, gears, and wheels.
The wind can blow in any direction.
Pull back wind up cars work by using a spring mechanism that is wound up by pulling the car backwards. When released, the spring unwinds and propels the car forward. This type of toy car is different from others because it does not require batteries or remote control to operate. Instead, it relies on manual winding and pulling back to generate movement.

Wind-up Car
wind it up
Wind up cars work a lot like a wind up clock except with far fewer gears. The spring spins an axle with a large gear on it. That gear drives a much smaller one on another axle that's attached to the wheels. A fancy wind-up will have a speed regulator of some sort (often nothing more than a couple of paddles driven by an intermediary gear. I'd recommend you drop by a local department store and buy a wind up car then take it apart. You'd learn (or be able to figure out) how to prevent the spring from unwinding when you don't want it to (some kind of pawl against the gear teeth). You'd also learn that you better have the car aimed properly before you take off because stopping that spring powered motor isn't going to be easy (maybe not even possible) once you unleash it.

wind farms are built and turbines are put up. As the wind blows it turns the turbines generating electricity.
They work off the same principle of magnets.
Wind deflectors allow for wind and rain to be deflected away from the passengers inside a car when the windows are open. They work because their shape and position make a car more aerodynamic, which forces the wind and precipitation around the open windows instead of into the vehicle.
