TL;DR: A self-contained apparatus for collecting, storing and transmitting solar heat includes an elongated insulated housing in which a quantity of heat retaining material is confined and a collector on one face of the housing which has a multi-layered glass face through which solar heat may pass and collect upon a unique heat-collecting bed which is insulated from the ambient environment by the glass face as discussed by the authors.

TL;DR: In this paper, a valved bypass circuit includes a heat absorption unit which can be included in the circuit when desired, and the upper exposed surface of the sand in the unit, at least, is covered with a layer of iron oxide.

TL;DR: In this article, the authors proposed a method of collecting, storing and transmitting solar heat, which includes the steps of absorbing solar heat on a collector surface, passing air across the collector surface in a heat transfer process whereby the heat absorbed by the collector surfaces is transferred to the air, passing the hot air leaving the surface through a horizontal duct disposed at a lower elevation than the surface, and passing hot air flowing from the duct into an elevated storage chamber containing material with heat absorbent and heat retaining characteristics.
