Not Just Turbocharging: Exhaust Gases Can Generate Electricity, Too

Green Car Reports

The exhaust gases shooting out the tailpipes of internal-combustion cars aren''t just a form of pollution, they also represent wasted energy. One way to use some of that energy has been turbocharging: An exhaust-driven turbine runs a compressor that packs more air into the combustion chambers, allowing more gasoline to be injected, thus producing
