摘要: A section of a cement block building, usually dwelling place, is illustrated with six versions the means to carry out basic concept. At some distance below earth's surface, temperature earth structure substantially constant. This statement in context normal building erected by man. The known increase at great depths excluded from operation this invention. depth which one must go experience constant year around temperatures will vary location and invention more useful those areas do not extreme variations, but require heat cooling for best comfort. surface huge sink, capable absorbing unlimited energy higher source, or giving lower level area. Thus, provides thermal transport depth, surrounds grid cause interior proximate temperature, warmer than winter cold cooler summer heat.
