„Selectively Permeable Biogas Container“

Researchers at the University of Hohenheim are investigating membrane materials which at room temperature and at normal pressure exhibit a high diffusion coefficient for CO2 and at the same time retain methane securely. The selectively permeable materials could be used in e.g. innovative biogas containers to increase the energy content of biogas in a very simple and effective way.

 

 

First printable thermoelectric generator (TEG): powerful, compact, flexible, scalable

Researchers of the Karlsruhe Institute of Technology (KIT) succeeded in developing a novel and cost-effective thermoelectric system which achieves the combination of the advantages of processing thin organic layers with the benefits of thick generators with high power. Through simple process variations it is possible cost-effectively to produce TEGs of any size which allow the fabrication of TEGs with the required output voltage, internal resistance and thermal resistance that are optimal for any given application.
