Abstract

The authors have been developing and testing an enhanced system of heated ground agriculture that uses buried plastic pipes to cool waste hot water and steam from municipal, CHP, and geothermal sources. The average heat dissipation rate is 3.3 kW of heat per square meter in test beds under 50 square meters. Plant data indicates increased yields of up to 20% and the successful small harvest of cultivars in outdoor settings that are only native to warmer climates. A heated green roof in New York City produced a small cotton harvest and January pansies. In 2018 a small harvest of non-indigenous oregano and turnips was commercially test marketed in Iceland. Test results indicate that a larger scale study to determine economic viability is warranted.
