ABSTRACT:
An electrical energy generating device which utilizes the potential difference between two dissimilar materials having different work functions and the ionizing properties of radioactive decay products is provided. A current generating cell includes a pair of electrodes of electro-chemically dissimilar materials separated by a space filled with a solid medium having a relatively high dielectric constant and a relatively low ionization constant. A current flows in an external circuit coupling the two electrodes together when the solid medium is ionized. Utilizing a suitable radioactive material mixed or dispersed in the solid medium provides an internal ionizing flux. Similarly, a current is generated in the external circuit when each of the electrodes are constructed of two plates of dissimilar materials in physical contact with each other and the medium is ionized.
