US11006586B2 "Energy efficient greenhouse," inventors Marc Plinke and Lindsey Schiller, assignee Ceres Greenhouse Solutions LLC; priority 2017-02-17; published 2021-05-18; status Active. Describes GAHT™: fan draws hot greenhouse air through manifold of pipes buried underground, cooling greenhouse while heating soil heat reservoir; later draws warm air back. States soil acts as thermal mass/heat reservoir; system also called ground-to-air heat exchanger or climate battery. Mentions typical underground soil temps about 50–60°F (10–17°C); configurable thermal reservoirs (water barrels etc.) and optional hydronic coupling.
