Turret mounted solar concentrator with boom mounted secondary mirror or collector

Patent ·
OSTI ID:5331060
A solar energy concentrator/collector assembly is disclosed employing an altitude-azimuth dual axis scanning mounting assembly including a base with a circular track for mounting the assembly for rotation about a vertical axis. The assembly includes a turret defining second pivotable axis normal to the vertical axis and intersecting the same. A boom, a concentrator and a collector act as a single rotational assembly during solar collection and fold together during non-operating periods to minimize the profile and wind loading. In one preferred embodiment the solar energy collector is fixed and located at the intersection of the two axes and a boom carries a secondary mirror reflecting solar energy from said primary mirror to the solar energy collector which may be a Stirling cycle engine or other heat engine. In an alternate embodiment the solar energy collector is located on the boom at the focus region of the solar concentrator.
