  • Balanced solar concentrator system
    Patent number: 4583520
    Abstract: This solar concentrator system is configured such that the base pedestal attachment point is located on the beam connecting the curved solar reflector and the heat energy receiver power conversion unit, herein envisioned as a Stirling engine. This attachment point is located near the balance point CG (Center of Gravity) of the power conversion unit-supporting beam-curved reflector subsystem such that the loads on the base pedestal and the attached solar tracking drive systems are minimized.
