Abstract : An angular tracking servo system for passive tracking of the sun which utilizes solar radiation to control the attitude of a mirror element in an array of Fresnel reflectors. The array collects and focuses solar energy onto a high efficiency conversion device. The energy required to move the mirror element is supplied by a gear system which is attached through a pivot arm to a vertically moving float immersed in a chamber containing water. (Author)
