that sounds like a reasonable approximation. Now if we add hydraulic storage:
per: http://www.hydac.com/fileadmin/pdb/p...0140000011.pdf
A 50 litre accumulator
with 400 bar maximum
pressure can supply
approx. 360 kJ = 0.1 kWh
(adiabatic).
50liters is about 100 pounds.

plus it needs a low pressure tank, so that is roughly 100lbs of fluid for 100watt hours of energy, plus tanks and stuff. It's enough energy to run the headlights for an hour maybe. to make 25hp (plus 10 from the ICE) for a half hour would be like 10,000 lbs of fluid. And you would have to sit there going nowhere for over an hour to charge it first.
