ALEXANDRIA, Va., July 23 -- United States Patent no. 12,366,383, issued on July 22.
"Solar evaporator for a parabolic solar collector using heat pump" was invented by Jean Koch (Brossard, Canada).
According to the abstract* released by the U.S. Patent & Trademark Office: "The solar evaporator is comprised of a parabolic dish structure and the evaporator located just outside of the focal point. The refrigerant, coming from the heat pump, circulates through the evaporator.
