Abstract

Pour exploiter l'énergie solaire, des moteurs dits solaires ont été mis au point, ces moteurs se présentant sous la forme d'un moteur thermique fonctionnant selon le principe du moteur Stirling à piston alternatif et fixé dans le foyer d'un miroir concave. Malgré le rendement de 42 % du moteur Stirling, l'installation n'a atteint qu'un rendement total d'environ 17 %, essentiellement en raison des pertes de chaleur au niveau du récepteur et d'un rendement relativement faible du concentrateur (Système de Schlaich & Partner). La présente invention utilise un moteur thermique inventé par le déposant pouvant être construit sans grands frais selon une forme très allongée grâce à un mode de fonctionnement relativement simple, de sorte que la surface du récepteur est, grâce à un miroir parabolique (rendement de concentrateur plus élevé qu'avec le miroir concave), relativement grande comparée à celle des moteurs solaires connus jusqu'ici et que l'on obtient ainsi un meilleur rendement total. Si l'on utilise la chaleur perdue de gaz d'échappement, ou similaire, à haute température, pour le réchauffage du récepteur du moteur thermique, cette invention permet de disposer d'une surface de récepteur également grande.
