L'installation de cette invention se compose également d'un module comprenant deux roues à ailettes et d'un générateur électrique conçu de façon que son rotor et son stator puissent tourner par rapport à un axe horizontal dans des sens opposés au moyen des roues à ailettes susmentionnées. L'une des roues à ailettes est couplée au rotor, tandis que l'autre est couplée au stator. Les ailettes des deux roues sont orientées dans des directions opposées, les roues étant elles-mêmes disposées de part et d'autre du générateur. Le rotor et le stator sont pourvus d'engrenages coniques dont les dents sont orientées les unes en direction des autres et entre lesquels se trouve un pignon conique pourvu d'un axe dépassant de l'installation et relié à un régulateur de vitesse de rotation. Le corps de l'installation se présente sous la forme d'un diffuseur cylindrique creux à l'intérieur duquel se trouve le générateur pourvu des deux roues à ailettes.
