MAGDEBURG. In late October the “German Environmental Prize” took place in Magdeburg. The German president, Frank-Walter Steinmeier, awarded prizes to two engineers Friedrich Mewis (l) and Dirk Lehmann (r), who have developed an energy-saving ship propulsion system. They designed a nozzle that is installed in front of the propeller, in order to reduce the consumption of heavy oil by up to ten per cent. According to both inventors, this nozzle is already being used on around 1,400 ships. The prize, which has been awarded since 1993, is worth 500,000 euros.
