Abstract

A subterranean furnace contains a shell in which a plurality of bricks are arranged in a mass. A mirror reflects sun light into the furnace chamber and onto a magnifying glass which concentrates the heat on the bricks. Air is circulated through the furnace chamber and is heated by the heat which is stored in the bricks. A gas burner is mounted beneath the mass of bricks to supply supplemental heat when needed.
