Claim 0:
1. A method for generating electrical potential or current or both through a pyroelectric process comprising the steps of:
forming a cohesive mass of polycrystalline zinc oxide crystals into a lozenge or tablet shape with dimensions of at least 1.0 inch×1.0 inch×0.18 inch and electrically conductive elements embedded or affixed on or into opposing regions, surfaces, or facets of the cohesive mass, and causing the polycrystalline zinc oxide crystals in the cohesive mass to remain in intimate physical contact and to remain electrically communicative with each other;
electrically connecting the cohesive mass of polycrystalline zine oxide crystals to an electrical circuit via said electrically conductive elements;
heating said cohesive mass of polycrystalline zinc oxide crystals for a first period of time and then cooling said cohesive mass for a second period of time to generate an electrical potential or current or both through the pyroelectric process.
