Now hydraulics, on the other hand . . .

We did a study and a simple Bicycle chain won hands down for power transfer.this was a while back!

Perhaps, but with hydraulics a smaller power plant can be used because the energy can be accumulated for power bursts and deceleration energy can be scavenged. It does everything electric hybrids attempts to do but far more efficiently and without the negatives of batteries.
