Along with exhaust gases, which are a product of combustion of fuel into the engines, a large amount of energy is thrown into the environment, among other things, the environment, among other things. Of course, it’s no secret that a person has long thought about using the heat of exhaust gas for benefit. But the reasons that restrained scientific progress is a low efficiency level, as well as the too high cost of the thermoelectric type converters. It was these factors that restrained the introduction of technology of such recovery. General Motors Concern a group of researchers with the assistance of scientists at the University of Purdu, actively developing a new type of car thermoelectric converter. Its use will allow the car to “eat” its own exhaust, while simultaneously converting it into electric energy. Such a step will significantly save material on fuel, and also reduce the load on the engine of a hybrid car.
