Steve,
It sounds like Williams might use KERS in 2010, but maybe not since the loss of Toyota.
Since Toyota based the Prius on a battery recovery system, its possible that was the reason to promote it. Cosworth might not have any interest in KERS. What have you heard?
The Prius gains a lot of acceleration from the recovery and general battery storage use. The second generation Prius electric motor provides 295 footpounds of torque by itself, just shy of the 300 footpound Ford Mustang 5.0 V8. Toyota limits the torque to protect the little axles.
As a side note, some electric rail switch yards pump dynamic braking energy back into the third rail, as recovered power to be used by other switchers in the same circuit.
