A political week - with a sad ending

27.08.2012 | posted by Jan Wörner

DLR got quite a bit of political attention last week, with a steady parade of three Federal ministers, a State minister and two State secretaries. Such contacts are very important for DLR because – rather than give a quantitative balance in terms of "what are you doing with the taxpayers' money?" – we are able to show them the work carried out at our research sites. Unfortunately, the weekend ended sadly with the death of a great man: Neil Armstrong.

Finished at last! The redesigned web portal for the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is ready to receive the first of its close to 500,000 visitors per month. We have been working on the redesign for some time now, and are more than pleased with the result. read more

'The Future of Energy' Year of Science: A different question every week, 1 answer and 150 comments

29.12.2010 | posted by Dorothee Bürkle

During 'The Future of Energy' Year of Science, DLR prepared one question each week on the topic of energy, answered by the science journalist, Jan Oliver Löfken. Users were invited to post their questions and comments on the blog, and we responded as they came in – we received a total of 150 contributions. Read 51 posts on our Energy Blog and see how researchers want to safeguard our energy supply in the future and what policies are being put in place for this in the world of politics. read more

Energy question of the week: Will our appetite for energy continue to increase?

27.12.2010 | posted by Jan Oliver Löfken

Our energy demand can be split into three main areas: electricity, heating, and fuel for mobility. In Germany, every person needs about 6000 watts of power to maintain his or her affluent, mobile way of life. Americans use almost twice that amount. Compare that with people in developing countries, like Chad, who only have 11 watts at their disposal. Is there a need for more and more energy? read more

Energy question of the week: How much electrical power can be harnessed from tides?

22.02.2010 | posted by Jan Oliver Löfken

Under the influence of the Moon's gravity, the water of Earth's oceans rises and falls twice a day. Powerful forces are at work all over the globe between every low and high tide – forces that can be harnessed to generate electrical power. Just how mature is the technology and what is the potential that tidal power stations could unleash? 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
