We can provide a much better and more flexible method of providing regenerative braking capability, and not just for cars.
We have mainly been describing ways that the Rolowitz Drive can improve the way motors accelerate loads, but there is another area in which it can be of enormous benefit, which is energy recovery. During acceleration energy is converted into motion; during deceleration that energy is liberated. In a conventional automobile the liberated energy is wasted. It is converted into heat and frictional wear on the brake parts, and in some cases frictional wear on the tires. In electric cars it is feasible to use what is known as regenerative braking, where the motor is used as a generator to put energy back into the batteries. Unfortunately this is a very inefficient process because of the methods being used. Batteries can only be charged at a certain rate, so if more energy is being derived than the battery can store at any given time, the remainder is wasted, again usually in the form of heat, which tends to shorten the life of electrical systems.
By using a pair of Rolowitz Drives arranged such that the output of one drives the input of the second drive whose output drives an energy storage device, either a generator or perhaps a flywheel or spring, a much higher proportion of the energy can be recovered.
This principle is not confined to automobiles. In the case of an automobile lift, almost all the energy required to lift the car can be recovered when the car is lowered, then used to raise the next car, resulting in huge savings of energy. The same applies to fans, pumps, bicycles and almost any other use you can think of.
