Stellate solar collector
First Claim
1. A solar collector device of the type adapted for heating water comprising:
- A. A base;
B. A perforated conduit supported in said base;
C. An elongated, opaque collector drum rotatably mounted upon said conduit, said drum having a stellate cross-section defining a series of radially extending vanes abutting at their tips to define drain apertures and a hollow interior, encompassing a mid-portion of said perforated conduit; and
D. A source of fluid connected to said conduit, such that fluid is expelled through the perforated portions of said conduit onto the interior surfaces of said vanes, so as to rotate said drum while being heated by conductive contact with the vane interior surfaces, as well as by convection and radiation within the hollow interior.

Abstract
A solar collector device of the type adapted for heating water and the like. An elongated, opaque collector is provided with a plurality of radially extending vanes so as to define a hollow interior of stellate cross-section. Water is sprayed through a feeding conduit which extends through the hollow interior. As the sprayed water accumulates upon the interior vane surfaces, the collector wheel is rotated according to the weight of the deposited water. As the vane tips are rotated downwardly, the water is heated by conductive contact with the interior vane surfaces and by convection and radiation within the hollow interior. The heated water is then discharged downwardly through apertures in the vane tips into a collector pan. The invention is distinguished from the prior art in its introduction of the water upon the interior surfaces of collector vanes within a paddle wheel of stellate configuration, rather than upon the exterior surfaces of the vanes. The stellate configuration provides an increased area of exposure to the radiation of the sun within a compact unit and provides heating of the water by conduction, convection and radiation.
