Basing their assessment on data gleaned from the Maglarp megawatt scale turbine -- which had steel blades stuffed with electronic measuring equipment -- military authorities in Sweden remain convinced that wind plant represent a serious risk to national security. Many siting applications are still being vetoed because of fears that turbines will disturb military communications, including radar and signal reconnaissance. In NATO countries, this kind of reconnaissance is made from the air, but in Sweden it is conducted from stations on the ground. A working group, which incudes the Swedish Windpower Association, SVIF, is now calling on organisations from around the world to share any experience they have of wind turbines disturbing communications. The working group is to take new measurements in the field on existing commercial turbines on Gotland and in the south of Sweden and experiment with special paint that minimises radar interference. Some 30 military experts are already involved in this work. The final report will be published in 1997 and made available to the international wind power community.
