This also excites me for waste heat recovery, Photovoltaic cells that respond to infrared – ‘thermovoltaics’ - can even capture radiation from a fuel-fire emitter; and co-generation of electricity and heat are said to be quiet, reliable, clean and efficient. A 1 cm2 silicon cell in direct sunlight will generate about 0.01W, but an efficient infrared photovoltaic cell of equal size can produce theoretically 1W in a fuel-fired system.
Once they get up and running the potential applications they can pursue or get involved with almost seem limitless, which means an income stream of mega proportions.
