An article on thermoelectric power generation from the exhaust pipe in cars. INteresdting stuff:

ScienceDaily (Jun. 4, 2008) Researchers are working on a thermoelectric generator that converts the heat from car exhaust fumes into electricity. The module feeds the energy into the car electronic systems. This cuts fuel consumption and helps reduce the CO2 emissions from motor vehicles.
...
The long-term objective is to make the alternator superfluous and to supply energy to the constantly rising number of power consumers in the car. TEGs could cover a significant proportion of a car's power requirements:This would make it possible to cut gas consumption by between five and seven percent,says Bottner.
5-7 percent here, 5-7 percent htere, pretty soon you're talking about real mileage savings. There's another 10-15 percent in the wings with camless engines and another 10 percent in variable compression too.
