Then, dashing behind the machines, he passes a hand over their exhaust heat.

Then, the exhaust heat from the bottom plate of the thermoelectric device would be used in the traditional way to warm water up.

Over the past three years, thermoelectric materials have attracted intense interest from energy researchers trying to turn exhaust heat from automobiles into electricity that can be used by the vehicle.

Fab 15 will be TSMC's next "green fab" following Fab 12 and Fab 14, incorporating green concepts in energy conservation and pollution control in its design, including a process water conservation rate of 85%, reclamation of rainwater, recirculation and reuse of general exhaust heat, and development of solar power generation and LED lighting applications.

With all of us starting to feel slightly ill from the heat, humidity, and exhaust fumes, we leave the crowded villages behind not a moment too soon and head into the lush green plantation country beneath Mount Kenya.

Thermoelectric materials convert low-grade heat wasted in industrial processes or exhaust systems of a vehicle into electricity.

Still, his team has led the complaints to Pirelli because Red Bull uses exhaust gases to improve its cars' rear downforce, which exposes the tires to more heat.
