Abstract
Abstract A solar energy device comprising a body having a plurality of spaced focusing lenses to concentrate direct and reflected rays from the sun. A heat receiving member is inside of said body. One of the body and the member is expansible and contractible so as to direct the member into exact convergence with the focal points of said lenses. The member is supported within said body and fed fluid to be heated. The heated fluid is then removed from the member. The heat receiving member that is expansible and contractible may be employed separately and used as a prime mover.
