A solar collector has a nonlinear collecting surface, for example, a substantially spherical surface, such collector being positioned perpendicular to the rays of the sun throughout the day thereby providing a constant level of solar energy collection. The collector has a hollow body where absorption of the collected heat takes place by a heat transferring fluid being either a liquid or a gas. Provisions are made for increasing the absorptive efficiency of the collector and for reducing radiant heat loss.

An apparatus for collecting solar energy comprising: a first rigid hemispherical member; a second rigid hemispherical member; said two members each having an opening at the apex and a circumferential flange at the periphery with an exterior surface having a solar heat absorbing coating thereon and being sized identically such that the two members may be joined as a sphere and restraining means associated with said flanges holding said members in fixed assembled relationship; an axle member insertable through said apex openings to extend beyond said assembled sphere on at least one end; said axle member connected to said sphere assembly by internal support members such that said sphere assembly is mounted on and carried by said axle member; at least one support frame to engage said extending end of said axle to support said axle and said carried sphere assembly; and means for directing a heat transferring gas into the interior of said sphere assembly to pick up heat energy from said sphere and means for extracting said gas after it has been heated.
