… how much heat is emitted by a red

hot steel slab while it cools down from

900°C to ambient temperature?

Is heat energy really waste?

… that in every combustion engine

driven vehicle 2/3 of your fuel

energy is converted into heat?

Have you ever thought about…

energy boostingo-flexxVision of O-Flexx

Waste heat is one of the biggest

but rarely used resources of energy.

O-Flexx‘s vision of a greener future is to exploit waste heat

by delivering novel world-class thermoelectric generators

and systems turning heat into electricity offering an to date

unrivaled level of efficiency.
