A closed-loop, solid-state system generates electricity from geothermal heat from a well by flow of heat, without needing large quantities of water to conduct heat from the ground. The present invention contemplates uses for depleted oil or gas wells and newly drilled wells to generate electricity in an environmentally--friendly method. Geothermal heat is conducted from the Earth to a heat exchanging element to heat the contents of pipes. The pipes are insulated between the bottom of the well and the surface to minimize heat dissipation as the heated contents of the pipes travel to the surface.

Un système à létat solide et à boucle fermée génère de lélectricité à partir de la chaleur géothermique provenant dun puits par circulation de chaleur, sans nécessiter de grandes quantités deau pour conduire la chaleur depuis le sol. La présente invention envisage lutilisation de puis de pétrole ou de gaz épuisés et de puits récemment forés pour générer de lélectricité selon un procédé qui ne nuit pas à lenvironnement. La chaleur géothermique est conduite depuis la terre vers un élément déchange thermique pour chauffer le contenu de tuyaux. Les tuyaux sont isolés entre le fond du puits et la surface afin de réduire au minimum la dissipation de chaleur lorsque le contenu chauffé des tuyaux se déplace vers la surface.
