kinetic energy ramp

The electro-kinetic road ramp is important and new to technology. This ramp generates energy from harnessing the kinetic energy from the automobiles going cross it. The energy comes from the automobiles that use the ramps. This ramp will produce 30 KW of electricity. This was dismissed before because of the talk of kinetic energy plates. It was said to be a waste of energy but I feel that it would be a good idea to try it again because it could really work. The kinetic energy caused by the friction of the tires on the car and the speed the car is going is what causes the ramp to function.
