Typical of rooftop turbines, the rotor is tied down on this non-operating turbine in Holzhausen, Rheinland-Pfalz, 2005. The turbine is noteworthy in its own right. The turbine is probably an Allgaier built in the years from 1950-1959. It appears to be a twin to a turbine atop the same company's building, Klöckner-Moeller, alongside the main north-south line from Bonn to Koblenz. The Allgaier was a derivative of the work by the father of German wind energy, Ulrich Hütter, and was built by a small company in the south of Germany in Göppingen (near Uhingen). Altogether, there were about 200 units built and ranged in size from 6-10 kW. A photograph similar to this and this background information is contained in "Windgeshichter" by Jan Oelker, 2005.
