Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
99 words
A light collector comprising a hollow collector chamber adapted to transmit light from outside said chamber into its hollow interior, inlet conduit means for passing luminescent fluid into the hollow interior of said chamber, outlet conduit means for removing luminescent fluid from the hollow interior of said chamber, heat exchange means for removing heat from the luminescent fluid in said outlet conduit means, photovoltaic means carried by said chamber for generating electricity, and said chamber carries in heat exchange relationship therewith a separate hollow cooling channel adapted to have a separate cooling fluid passed therethrough to cool said chamber.
Claim 2
Dependent Claim
99 words
A light collector comprising a hollow collector chamber adapted to transmit light from outside said chamber into its hollow interior, inlet conduit means for passing luminescent fluid into the hollow interior of said chamber, outlet conduit means for removing luminescent fluid from the hollow interior of said chamber, heat exchange means for removing heat from the luminescent fluid in said outlet conduit means, photovoltaic means carried by said chamber for generating electricity, and said chamber carries in heat exchange relationship therewith a separate hollow cooling channel adapted to have a separate cooling fluid passed therethrough to cool said chamber.
Claim 3
Dependent Claim
27 words
A device according to claim 1 wherein there is recycle conduit means for returning cooled luminescent fluid from said heat exchange means to said inlet conduit means.
Claim 4
Dependent Claim
29 words
A device according to claim 2 wherein there is pump means for cycling luminescent fluid from said outlet conduit means through said heat exchange means and recycle conduit means.
Claim 5
Dependent Claim
18 words
A device according to claim 1 wherein said cooling channel is coextensive with one side of said chamber.
Claim 6
Dependent Claim
20 words
A device according to claim 1 wherein said cooling channel is coextensive with a plurality of sides of said chamber.
Claim 7
Dependent Claim
43 words
A solar collection method comprising exposing a hollow light transmitting chamber which carries photovoltaic means to sunlight, passing a gaseous luminescent fluid through said chamber, recovering heat from said fluid after it passes through said chamber, and recovering electricity from said photovoltaic means.
Claim 8
Dependent Claim
43 words
A solar collection method comprising exposing a hollow light transmitting chamber which carries photovoltaic means to sunlight, passing a gaseous luminescent fluid through said chamber, recovering heat from said fluid after it passes through said chamber, and recovering electricity from said photovoltaic means.
Claim 9
Dependent Claim
19 words
The method according to claim 6 including passing a heat exchange fluid in heat exchange contact with said chamber.
Claim 10
Dependent Claim
64 words
A solar collector comprising a closed hollow chamber adapted to transmit light from outside said chamber into its hollow interior, a luminescent fluid in the closed interior of said chamber, a hollow cooling channel in heat exchange contact with said chamber, means for passing a cooling fluid through said channel, means for recovering heat from said cooling fluid, and photovoltaic means on said chamber.
Claim 11
Dependent Claim
64 words
A solar collector comprising a closed hollow chamber adapted to transmit light from outside said chamber into its hollow interior, a luminescent fluid in the closed interior of said chamber, a hollow cooling channel in heat exchange contact with said chamber, means for passing a cooling fluid through said channel, means for recovering heat from said cooling fluid, and photovoltaic means on said chamber.
Claim 12
Dependent Claim
18 words
A device according to claim 8 wherein said cooling channel is coextensive with one side of said chamber.
Claim 13
Dependent Claim
20 words
A device according to claim 8 wherein said cooling channel is coextensive with a plurality of sides of said chamber.
Claim 14
Dependent Claim
52 words
A light collecting method comprising exposing a closed hollow light transmitting chamber which carries photovoltaic means thereon and a luminescent fluid therein to light, passing a separate cooling fluid in heat exchange contact with said chamber to cool same, recovering heat from said cooling fluid, and recovering electricity from said photovoltaic means.
Claim 15
Dependent Claim
52 words
A light collecting method comprising exposing a closed hollow light transmitting chamber which carries photovoltaic means thereon and a luminescent fluid therein to light, passing a separate cooling fluid in heat exchange contact with said chamber to cool same, recovering heat from said cooling fluid, and recovering electricity from said photovoltaic means.
Claim 16
Dependent Claim
17 words
A method according to claim 11 wherein said luminescent fluid is liquid, gaseous, or a combination thereof.
Claim 17
Dependent Claim
30 words
A method according to claim 11 wherein said luminescent fluid is a liquid which contains at least one organic dye luminescent agent dissolved in a liquid solvent for said dye.
