there is an aussie company that is doing something for a trucks engine, its hydrolic somethings change directions so the the oil used for breaking is stored pressurised and when the driver accelerates that oil is re-used to accelerate faster. it saves something like 60 feet of the bearking times 100 kph-0 and 27 or so % of fuel ecconomy. i cant remember if thats correct, but its very impressive.
