These principles point us to the ultimate clean, non-depleting energy source: We would collect electromagnetic energy by cycling atoms–in the form of non-toxic, non-reactive noble gases—through a closed system of tiny Casimir cavities, consuming only a small fraction of the energy released in this process. The harvested energy can be used as heat or converted photovoltaically into electricity. The devices could be scaled for larger power applications and mass-manufactured cheaply using stamping techniques. The patent specifying our technique describes in detail the physical interpretation of a fundamental quantum axiom, by which zero-point fluctuations of the quantum vacuum field support electron orbital energy levels.
