In cars with internal combustion engines, a large part of the energy stored in diesel or petrol is simply dissipated as lost heat. It is precisely these hot exhaust gases that an increasing number of scientists worldwide want to use for more efficient electricity generation. They are developing and testing thermoelectric generators that can generate electricity from temperature differences of several hundred degrees. But does electricity from hot car exhaust gases really save fuel? read more
