Living Off the Grid in the City Radio (Legacy) Show. There are other solar technologies that may enable you to get off the grid. The photovoltaic effect history is briefly discussed here. These other solar technologies include solar coolers, non-electric refrigerators, and electric non-moving-parts heaters and air coolers. These technologies are based on solar concentrators, thermocouple and thermo-electric effects. These concepts and technologies may allow the curious and ingenious to generate heat, cold, and electricity using heat energy from the sun.
