Generating rainfall for deserts using wind power and seawater is the subject of a new research project.
The idea involves the installation at sea of specially designed wind turbines. The turning motion of the rotors would be harnessed to pump seawater along the turbines’ hollow blades. The water would then be forced out through slits as a fine spray. These drops would evaporate, with salt falling back into the sea and a cloud of water vapour drifting inland, increasing the probability of rain.
The project is being funded by the Swindon-based Engineering and Physical Sciences Research Council, and led by Professor Stephen Salter, the University of Edinburgh’s world-renowned marine energy expert. It will first assess the feasibility of the concept, with emphasis on the meteorological aspects.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
