Waste Heat

Waste heat is by necessity produced both by machines that do work and in other processes that use energy, for example in a refrigerator warming the room air or a combustion engine releasing heat into the environment.

  • Electricity from waste heat made possible by ceramics

    Where conventional materials reach their limits, ceramics can display their excellent properties. Functional ceramics – so-called thermoelectric materials – can convert waste heat directly into electricity, for example, in high-temperature processes. At the Hannover Messe 2016, Europe's largest ceramics research institute presents for the first time a system that demonstrates the reliable functionality of thermoelectric ceramic modules developed at Fraunhofer IKTS.
