Background: In West germany, experts are studying the feasibility of large-scale use of electricity generated from wind power. The scientists have been carrying out their experiments at the wind power tower at Brunsbuttel on the Elbe estuary, 65 kilometres (40 miles) north east of Hamburg. The tower is one of the largest of its kind in the world. It was completed recently after 12 months construction work. Spurred on by high oil price rises in the 1970s, the Ministry for Research and Development authorised the project. Wind speeds of only 20-kilometres-an-hour (12 1/2 miles-per-hour) are needed for the tow-blade rotor, with a span of 100 metres (yards), to start generating electricity. The blades can be turned to face into the wind and the tower reaches optimum output of 3,000 kilowatts at wind speeds of between 40 and 90 kilometres an hour (25 and 57 miles per hour). The tower can be run automatically if desired, and output readings are continually assessed by computer, The project is aimed at domestic power consumption rather than industrial uses.
