Solar Thermal Waste Heat Engine works at low temperature, low pressure

Technology capable of generating electricity by extracting energy from heat that is otherwise just wasted is a fairly new branch of renewable technology. A typical co-generation plant uses waste heat from a gas or steam turbine for hot water or space heating. This Waste Heat Engine (WHE) developed by Cyclone Power Technologies operates at temperatures as low as 225F (107 C). The engine can generate up to 10kw from heat sources such as industrial ovens or furnaces, concentrating solar thermal collectors, engine exhaust and biomass combustion. Read More
MIT students develop Hydraulic Regenerative Shock Absorbers

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.
