Abstract
A capacitive coupler provides high coupling capacitance through the use of an electrolyte and insulator formed as an oxide layer on at least one plate of the coupler. The coupler can be independent or provide a hydrodynamic or hydrostatic bearing as well as capacitive coupling, and the circulated dielectric can provide for cooling of associated machinery.
