Patent ID: 7335892

Claim:
A source of electrical energy, comprising: an energy cell, including: (i) a first element formed of a first material, said first element being effective to eject a quantity of electrons in response to impingement by high energy photons; (ii) a second element spaced from said first element, said second element being formed of a second material which is effective to eject a lesser quantity of electrons, compared to said first element, in response to impingement by high energy photons, an electrical potential being created across said first and second elements which produces an induced electromagnetic force charge; (iii) a first dielectric material located between said first and second elements; a switching device coupled to said energy cell, said switching device comprising: (i) a third element mounted in a fixed position, said third element being formed of a third material which ejects electrons in response to impingement by high energy photons; (ii) a fourth element spaced from said third element, said fourth element being formed of a fourth material which ejects a lesser quantity of electrons, compared to said third material, in response to impingement by high energy photons; (iii) a mounting device coupled to said fourth element, said mounting device permitting movement of said fourth element relative to said third element; (iv) a second dielectric material located between said third and fourth elements; (v) said third element being effective to repel and move said fourth element to a discharge position when a sufficient quantity of electrons is present on said third element and on said fourth element as a result of said impingement by high energy photons; a contact adapted to couple to a load, said contact being positioned with respect to said switching device so as to engage said fourth element upon movement of said fourth element to said discharge position thus permitting a discharge of said induced electromagnetic force charge from said energy cell through said switch to the load.
