Abstract
Abstract A fluid stream with entrained phosphorescent particles is used to transfer solar radiant energy to a light-release zone where the passage of the stream and particles through suitable light emitting containment means will permit both radiant heat and light emission into such zone. Typically, the heated fluid stream will also be passed to a heat recovery zone, as well as through at least one light releasing zone, such that a major portion of the heat content of the stream and particles can be recovered for immediate use or stored.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
A method for effecting the useful recovery of energy from solar radiant energy which comprises: a. passing a fluid stream with entrained phosphorescent particles to a solar radiant energy exposure zone and effecting the absorption of both heat and light energy into such particles and stream, b. passing at least a portion of the resulting light regenerated phosphorescent particles in the carrying fluid stream to a light release zone and providing for the passage of such particles through light emitting containment means to, in turn, provide for light emission therefrom into said light release zone, and c. subsequently returning the stream and particles to said solar energy exposure zone for reheating and re-exposure to sunlight.
Claim 2
Independent Claim
115 words
A method for effecting the useful recovery of energy from solar radiant energy which comprises: a. passing a fluid stream with entrained phosphorescent particles to a solar radiant energy exposure zone and effecting the absorption of both heat and light energy into such particles and stream, b. passing at least a portion of the resulting light regenerated phosphorescent particles in the carrying fluid stream to a light release zone and providing for the passage of such particles through light emitting containment means to, in turn, provide for light emission therefrom into said light release zone, and c. subsequently returning the stream and particles to said solar energy exposure zone for reheating and re-exposure to sunlight.
Claim 3
Dependent Claim
47 words
The method of claim 1 further characterized in that the fluid stream and entrained particles are passed from said light release zone to a heat exchange-heat recovery zone wherein heat is taken from said stream and particles prior to their return to said solar energy exposure zone.
Claim 4
Dependent Claim
26 words
The method of claim 1 further characterized in that the fluid stream is a liquid medium in order to maximize the heat capacity of the stream.
Claim 5
Dependent Claim
46 words
The method of claim 1 further characterized in that a fluid stream by-pass means is provided with respect to said light emitting containment means and flow control means to the latter and to said by-pass means provide for regulating light emission into the light release zone.
