We reported recently on several new methods of regeneration for hybrid vehicles. These included regenerative shocks based on electric motors and a hydraulic drive train. Now students at MIT have developed a regenerative shock absorber that is a cross between those two. Fitted to a heavy truck, each shock absorber could generate up to an average of 1 Kw on a standard road, completely displacing the large alternator load and even running accessory devices such as hybrid trailer refrigeration units.
