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

18.01.2010 | posted by Jan Oliver Löfken

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

Visiting Solar Impulse

A special impulse ... Solar Impulse

A very special experience: I had the opportunity to observe at first hand the work of DLR's staff on Solar Impulse, Bertrand Piccard and André Borschberg's project to circumnavigate the world in a solar-powered plane. read more

Energy question of the week: How much energy does the Sun send us every day?

12.01.2010 | posted by Jan Oliver Löfken

Our Sun is a gigantic fusion reactor with an expected lifetime of about ten billion years. Although this period of time is unimaginably long from a human perspective, half of it has already elapsed. That means that our star, a very ordinary one in astronomical terms, will still be radiating the same amount of energy as it now does long after our resources of uranium, coal, gas or crude oil have been used up. How much energy from the Sun reaches us here on Earth? read more

Which energy source will we use in the future? DLR Energy Blog for ‘Energy’ Science Year

12.01.2010 | posted by Dorothee Bürkle

Can we refuel in the future simply using the Sun? How long will the Earth’s oil reserves last? Which energy source will our grandchildren use? Many people are asking scientific researchers about the future of our energy supply. The German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung; BMBF) has chosen the slogan ‘The Future of Energy’ for Science Year 2010. In the DLR Energy Blog, science journalist Jan Oliver Löfken will answer a question about energy each week during the year. read more

2010 ...

Welcome to the DLR Blogs

12.01.2010

Today, we have taken our new DLR Blogs platform live; we wish to offer you a warm welcome. We are starting with three blogs. Firstly, there is a blog by Jan Wörner, chairman of the DLR Executive board, who offers insights into his work. Secondly, we have started our NewsBlog, in which we intend to publish the short stories, pictures, videos or other items of interest that do not find a place on the homepage of our web portal – www.dlr.de/en. Last but not least, there's the EnergyBlog. The German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung; BMBF) has nominated 'The Future of Energy' as the topic for the german Science Year 2010. This is more than sufficient reason for us to address the subject with a dedicated blog, in which we will also answer an 'Energy Question of the Week'. read more
