Jan Oliver Löfken

Energy journalist Jan Oliver Löfken writes among other things, for the Technologie Review, Wissenschaft aktuell, Tagesspiegel, Berliner Zeitung and P.M. Magazin on issues involving energy research and industry. For DLR, he answered the Energy question of the week during the Year of Energy 2010.

Currently, Jan Oliver Löfken writes in the DLR Energy blog on current topics related to the energy turnaround. He considers the contributions that research can make to a secure and affordable energy supply. The energy transition is a social challenge - a project of the century, as noted by Environment Minister Peter Altmeier. In the DLR Energy Blog, Jan Oliver Löfken discusses the outlook of the power supply and what can set the course for politics and the economy today.

Energie-Frage der Woche: Der Autoauspuff als Stromquelle?

In Autos mit Verbrennungsmotoren verpufft ein Großteil der in Diesel oder Benzin gespeicherten Energie als Abwärme. Gerade diese heißen Abgase wollen weltweit immer mehr Wissenschaftler für eine effiziente Stromgewinnung nutzen. Sie entwickeln und testen thermoelektrische Generatoren, die aus Temperaturunterschieden von mehreren hundert Grad elektrischen Strom erzeugen können. Doch spart Strom aus heißen Autoabgasen wirklich Treibstoff? read more

Energy question of the week: Car exhaust gases as a source of electricity?

In cars with internal combustion engines, a large part of the energy stored in diesel or petrol is simply dissipated as lost heat. It is precisely these hot exhaust gases that an increasing number of scientists worldwide want to use for more efficient electricity generation. They are developing and testing thermoelectric generators that can generate electricity from temperature differences of several hundred degrees. But does electricity from hot car exhaust gases really save fuel? read more
