NaturMobil One Horsepower Car

NaturMobil one horsepower car is literally powered by one horse jogging on a treadmill.
This ecological vehicle is designed by Iranian engineer Hadi Mirhejazi. According to him NaturMobil was able to reach speeds of up to 28mph.
When starting the car, the driver simply turns on the treadmill. The horse begin to gallop ant that movement recharges the treadmill’s battery, and keeps the vehicle going.
In order to brake, you’ll need to turn off the treadmill, slowing down the horse.
Of course, there are some problems with this design. Bad smell and odor from horses waste collected in this container.
Designers plan was to take a publicity road trip around the world but the plan never came off.
