Concept

Waste heat is one of the largest unexploited energy resources in the world. 60% of all energy produced is thrown away as waste heat. If we could recover just 1% of this, it would be equivalent to a staggering $100,000,000,000, or 300,000,000 tonnes CO2. Until now materials for transforming waste heat into electrical energy have been in short supply and not useful at temperatures above 200 ºC

Now, the Danish company TEGnology has the solution in terms of two cheaper and efficient materials for the transformation process. This means that some very compelling goals can be achieved such as better fuel economy, less CO2 and cheaper operation.

The TEG-technology can for instance make the petrol-based hybrid cars of the future more energy-efficient, making the cars even more environmentally friendly. Tests show that when new materials are used in a Thermoelectric Generation (TEG) process, the fuel efficiency of the car can increase by up to 10%.
