For the past two years, Südwind has been marketing agent in Germany for the VS 45, the manufacturing licence for which was obtained by Markham from the design's developer, Pehr Windtechnology of Austria. This role will now be undertaken by Christopher Schirren, formerly of GET-Danwin. A prototype of the VS 45 is currently under scrutiny at the Kaiser Wilhelm Koog wind test field in Germany. A series of teething problems are now solved, says Markham's Nick Bristow. Markham is part of Britain's Trafalgar House group.
Originally the design was marketed by Pehr under the name Floda, with projects installed in California and Israel. Now four different versions of the machine are being developed and marketed. Licenses have been granted by Pehr to an Israeli company as well as to Südwind and Markham. An independent wind consultant, Gerald Hehenberger of Wintec in Austria, is also developing a 600 kW, the prototype of which will be installed within a year. Hehenberger was closely associated with the design of the original Floda.
Südwind intends to take the machine away from its variable speed beginnings and develop a design along more traditional Danish lines. A prototype of the Südwind N 4560 will be installed before the end of the year and marketing will start in 1996. "The decisive factor for us in stopping the arrangement was that we have wanted to develop a large machine for some time but didn't have the financing," says Südwind's Claus-Dieter Santen.
