Among the projects discussed were reducing cold starts; using waste heat for different heating applications in the car; and a new implementation of a thermoelectric generator (TEG) for waste heat recovery. Heating with waste heat. Encapsulating the engine for heat retention. Click to enlarge. No more cold starts.

The K6 engine uses six strokes instead of four to reduce the pressure of exhaust gases, which allows it to harvest more energy rather than expelling it with the gas. Slowly decompressing the gases would waste less of that energy and make for a much quieter engine. —Timothy Shedd. Kashmerick and Timothy A.

In other words, of the energy available in a gallon of gasoline, a third is lost as waste heat, another third disappears out of the exhaust with only the remaining third available for useful work. A traditional rule of thumb decrees that the conventional gasoline engine achieves efficiency of around one third.

The anaerobic digester is fed the waste from the distillation process and the wastes from 2,000 dairy cattle and 10,000 beef cattle being raised on the site. Madson identified several ethanol plants that were built in industrial settings that were able to use the waste heat, i.e. from an adjacent refinery, to produce their ethanol.
