One of the latest “crazy” environmentally-friendly ideas is this screwdriver-powered EX vehicle.
The EX is a tricycle that uses 18-volt screwdrivers as engines that allow the vehicle to register a top speed of 30 km/h (which is pretty normal in a car-stuffed megapolis).
The author of this vehicle is Nils Feber. He made EX from the ground.
The design of the vehicle places the driver in horizontal position with both arms outstretched holding the wheel.
Both throttle and brakes work just like in any normal motorcycle. In addition, the custom-made joint makes the read section of the vehicle tilt when the driver leans into curves.
It would be interesting to note that most of the parts used to built the EX vehicle were borrowed from old bicycles.
Nils mentioned that he was inspired by a skeleton and its organs when he designed the vehicle.
