Abstract
A solar energy collector having a transparent pane(s) with a flowing "black" liquid medium to absorb the solar energy directly. The specific apparatus comprises in a general embodiment a tubing of various planar configuration to provide a flat surface. Alternative embodiments include the free flow of a black liquid over a flat surface. Other structure is described for heat retention and environmental control. The black liquids have a high rate of absorption to solar energy.
