2122353 9309390 PCTABS00022 A solar energy collecting apparatus (10) including a platform (13) supported for rotational movement about a vertical axis, a drive for pivoting the platform about the vertical axis to track movement of the sun, solar energy collectors supported on the platform, and concentrators (27) for directing the solar energy to the solar energy collectors. The concentrators (27) are a plurality of parallel elongated reflectors supported on the platform (13), where each reflector is parabolic to concentrate solar energy on a horizontal focal line, and the energy collectors are supported at the focal lines of the reflectors. The platform (13) may be supported for floating movement on a fluid in a fluid reservoir (12) or other body of fluid. Liquid may be pumped over the platform (13) to selectively submerge the concentrators (27) for protection against inclement weather conditions.
