If anyone out there knows people that work with tractor, bobcats...etc...They would understand the hydrostatic transmission. This is off the shelf tech just used in a novel way.
In the 1970's during the oil crisis a man called Vincent Carman came up with a system to increase car mileage dramatically, with a hydraulic transmission hybrid. The Carter administration sat on him. Carman thought he would get a hero's welcome but was stonewalled at every turn. I think his ideas were practical and do able and hopeful internet buzz will finally get his ideas out.
Vincent Carman's prototype got 38.5mpg City with a 4200lb behemoth that normally gets 15mpg (a 250% improvement!). A Prius gets ~50mpg city in a chassis that would get about 25-30mpg city (a mere 100%improvement). This would suggest a hydraulic Prius could get 65-70mpg city! Of course a Prius only has a 100lb battery, so it is hardly a hybrid with so little storage. Thus the poor mileage. The gas engine is really doing most of the work.
Here is an article from 1977
CAN THIS TRANSMISSION REALLY DOUBLE YOUR CAR' S MILEAGE?
Ernie Parker a tech teacher at tech college got together with his students and made another version in 1978:
THIS CAR TRAVELS 75 MILES ON A SINGLE GALLON OF GASOLINE!
Ernie's sons now do these transmission for motorcycles and off road vehicles and sell DVD's on how to do it.

They should get together with Aaron, Peter, and John Bedini sometime!
