Title: Use of solar energy heat gathering and storing systems to increase farm crop yields
Abstract:
In a solar heat collecting and storage system in which mirrors reflect sunlight on a heat storing material such as a pile of pebbles, with air being drawn into the pile of pebbles so the heat accumulating on the surface of the pile is drawn into the center of the pile of pebbles, is located an artificial light of the correct color so that it will produce crop growth. When the sun is not shining the mirrors, that have been used to collect solar heat, are used to reflect this artificial light over growing crops and thus produce crop yields greater than normal.
