Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 133 words
An electric current generating cell comprising: an open-cellular foamed semiconductor; a vessel containing such open-cellular foamed semiconductor; a continuous electroconductive layer formed around the outer sides of said open-cellular foamed semiconductor; means to excite said semiconductor to produce electric current; electrode means to carry said electric current outside said open-cellular foam semiconductor, said electrode means being further adapted to form said cells output terminals, said electrodes means including: a first electrode entered into said vessel and surrounded by said open-cellular foam semiconductor; a second electrode contiguous with said continuous electroconductive layer around said open-cellular foamed semiconductor; and said means to excite said semiconductor including: means to enter gas into said cell; and a gas entered into said cell through said means to enter gas to cause the production of electricity from said cell.
Claim 2
Dependent Claim 133 words
An electric current generating cell comprising: an open-cellular foamed semiconductor; a vessel containing such open-cellular foamed semiconductor; a continuous electroconductive layer formed around the outer sides of said open-cellular foamed semiconductor; means to excite said semiconductor to produce electric current; electrode means to carry said electric current outside said open-cellular foam semiconductor, said electrode means being further adapted to form said cells output terminals, said electrodes means including: a first electrode entered into said vessel and surrounded by said open-cellular foam semiconductor; a second electrode contiguous with said continuous electroconductive layer around said open-cellular foamed semiconductor; and said means to excite said semiconductor including: means to enter gas into said cell; and a gas entered into said cell through said means to enter gas to cause the production of electricity from said cell.
Claim 3
Dependent Claim 43 words
The electric current generating cell of claim 1 wherein said gas is a radioactive gas and said continuous polycrystalline semiconductive layer contains a luminescent material that emits rays when excited by said radioactive gas, said rays causing said cell to produce electric current.
Claim 4
Dependent Claim 43 words
The electric current generating cell of claim 1 wherein said gas is a radioactive gas which gas further contains an ionizable gas that emits ray when excited by said radioactive portion of said gas, said rays causing said cell to produce electric current.
Claim 5
Dependent Claim 69 words
The electric current generating cell of claim 1 further including: a metallized electroconductive layer coated around said opencellular foam semiconductor; and a vacuum chamber formed around said metal coated opencellular foam semiconductor; said first electrode extending from within the metal coated open-cellular foam semiconductor; and said second electrode positioned in the vacuum chamber formed around the metal coated open-cellular foam semiconductor, said second electrode contacting said metallized electroconductive layer.
