A system and method for capturing waste heat and converting the captured waste heat into mechanical or electrical energy. The device includes a column with three sections. Also disclosed are processes for fabricating a catalyst material for use in the electrolytic reactors and processes. Formation of the container cell is self-aligning wherein previously-formed gate stacks act as etch stops for the container cell etch. The circuit board includes portions positioned directly behind the cross-connect array and the INOUT array. A control module is operably coupled to a discrete RF switch associated with each shorting pin to set the operating frequency characteristic of the patch antenna by selectively connecting the patch to the ground plane through one or more of the plurality of shorting pins.
