Traffic monitoring with the TerraSAR-X/TanDEM-X satellite constellation

Traffic monitoring from space, day and night, from more than 500 kilometres up above; is that possible? Indeed it is! In fact, it has been demonstrated several times in the past – once with the Shuttle Radar Topography Mission (SRTM), and again with TerraSAR-X. The traffic processors used with SRTM and TerraSAR-X were and are still subject to considerable limitations. read more

A volcanic eruption affects the whole of Europe

As of today, nearly all Europeans know that Iceland has active volcanos, and some are even familiar with the name Eyjafjallajökull. The consequences of the eruption have paralysed air traffic over a wide area. DLR was able – as were its partner organizations, NASA and ESA – to use its expertise and access to appropriate satellite data to inform the public about the extent of the problem. read more

Will we be driving only electric cars in twenty years' time?

The first, purely electrically-driven compact and sports cars are already on the market, but they are much more expensive than their classic diesel or petrol engine counterparts and have a range of no more than 100 kilometres. Only light, high-performance and cheap lithium-ion batteries will help electric cars achieve a breakthrough. Will such electricity storage devices reach production standard in the near future? read more

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
