Brokaw, H R

A solar apparatus is provided for heating liquids such as water, to a high temperature by utilizing a movable parabolic heat collector to concentrate the sun's rays associated with a special piping arrangement to obtain progressive liquid pre-heating; a collector tracking device including photocells and a collimating system for controlling the movement of the collector to maintain alignment with the sun; a device for modulating the flow of the heat transfer liquid between the collector and the storage to maintain optimum heat replenishment therebetween; and also a vacuum insulated heat exchanger to isolate the heat transfer liquid from the water being heated.
