The concept of turning waste heat into energy is hardly new
, but it looks like it's getting a little closer to your engine these days. Heat2power is similar to other systems that are designed to take the excess heat that normally goes out the exhaust pipe and turn it into go power, but the claim is that this one bests them on efficiency -- to the tune of reducing fuel consumption 20 percent in the city and 35 percent on the highway. The best news is that the device, which hooks right into the crankshaft, is compatible with "any" internal combustion engine. Of course, that's big talk for a company that doesn't have an exact product
yet. It also seems like retrofitting would be a bit rough. The estimated additional cost to a vehicle is in the range or 300 to 400 euros (about $500 US).
