Abstract
A heat exchange liquid has a heat absorption rate between about 40,000 BTUs per pound--one million BTUs per pound, and is useful with any conventional solar energy collection equipment. The heat exchange liquid is passed in heat exchange relationship in a closed loop through a heat conductive conduit system into operative association with a solar collecting device, and absorbs heat at the device. The heat exchange liquid is non-combustible, non-toxic, and biodegradable and has a pH of between about 7.4-7.6. The major component of the concentrate which forms the heat exchange liquid is a linear alkylate sulfonate, non-ionic detergent and lauric superamide detergent mixture. It also includes dark colored (e.g. black) vegetable color, vitamin B-6, and bicarbonate soda or alfalfa. The concentrate can be mixed with water, and comprises about 20-99.9 percent of the heat exchange liquid, while the water comprises the remaining about 0.1 percent-80 percent.
