Other high-power wind turbines have been tested at that time, on an experimental basis. It is not about to be exhaustive about them.

To quote, among contemporary wind turbines that of Nogent-le-Roi:

  • The asynchronous Smith-Putnam wind turbine with a two-blade variable pitch, manufactured in 1945 by Morgan Smith Co to Grandpa'Kbob (Vermont, USA) with a rated output of 1250 kWh. The propeller had a diameter of 53 meters. It lost one of its blades in a trial and was scrapped.

  • Neyrpic asynchronous wind turbines of 130 and 1000 kWh, which were operated by EDF in Saint-Rémy-des-Landes (Manche), along with that of Nogent-le-Roi. The machine of 130 kW was scrapped in 1965 and that of 1 000 KWwas dismantled and taken over by Neyrpic, as EDF had suspended the search. Used industrially, the 1 000 KWwind turbine has produced 500,000 kW during 7 months of actual operation. Its record of power has been of 1085 kWh. The variable pitch propeller was hydraulically driven (see Minutes).

  • The plan that fell through in 1963. That year, Lucien and Romani and the BEST presented to the Direction des Etudes et Recherches of EDF a project of wind turbine that could be erected without the intervention of a monumental crane and then to run unattended on place.

It followed many previous studies, conducted with the help of the Laboratoire Central des Ponts et Chaussées, LBTP, l'O.N.E.R.A., Breguet, CIMT, Sud-Aviation, 'Entreprise Générale Industrielle, Neyrplast, Alsthom, Société des Monteurs-Levageurs, etc...

It was planned two counter-propeller turbines 32 meters in diameter, close to one another and located in the same plane on a tour truncated by thin web of reinforced concrete. Each propeller would have driven, via multiplier, a synchronous generator of 1000 kWh.

The wind tunnel tests conducted at the Velizy Breguet had proved that this provision provided a gain of 10% compared with two similar helices distant from one another.

Economic studies conducted by the Direction de l'Equipement of EDF showed that, based on an average usage of 2150 hours / year, the cost of energy would have been 30 to 50% higher than energy produced from oil. The project was abandoned.

  • The 1984 Neyrpic project. A visitor tells me that « In 1984 a new project arises. This was the eventual realization of a wind turbine of 25 m with the CEA, the help of the Agence Française pour la Maîtrise de l'Energie and of the EEC. But the situation was not favorable because on the side of EDF the judgment was still poor overall (thus no intention on their part to finance in this area) » to which one must add « on the side of AFME some difficulties. Neyrpic was unable to obtain all needed help and, in 1985, had to admit that its project was in "bad shape" (I quote). Note: For the record, from what I've read, this machine would probably have been installed in Corsica. »
