<p>A radiant energy collecting apparatus including a fluid reservoir, a platform floating on said fluid reservoir, a drive structure for moving the platform on the reservoir, radiant energy collectors supported on the platform, reflectors for concentrating radiant energy on the radiant energy collectors, and means for selectively submerging the concentrating means beneath fluid from the reservoir for protection against inclement weather conditions. Fluid feed impellers are supported beneath the platform within the reservoir and communicate with ports through the platform for pumping fluid onto the platform and reflectors. Opposing fluid impellers are associated with each fluid feed impeller, the opposing impellers being operable with the feed impellers to force fluid in an opposing direction to the feed impellers, with deflectors being disposed between the feed impellers and the opposing impellers. A duct is associated with at least one impeller and is configured so as to direct fluid adjacent the at least one impeller in a vertical direction and direct fluid through its other end at least partially in a horizontal direction. Flotation devices secured to the platform support the platform when the reflectors are submerged beneath fluid from the reservoir, the buoyancy of the flotation devices per unit height increasing from bottom to top of the flotation devices. Alternatively or in addition, a low pressure is established beneath the platform to restrain the platform against the buoyant force on the platform.</p> |
