This invention relates to a geothermal system of heat exchange and more particularly to a geothermal pile that is disposed in the ground inside a contained source of water. Through this method we can harness the heat energy present that is underneath the surface of the earth. It is said to be one of the most abundant sources of heat on earth and through proper utilization of this heat energy we aim to reduce energy consumption through conventional means. The FeBTUCellTM has an expected co-efficient of efficiency (COE) of 10, which is the highest COE observed in dry-ground. Furthermore, the FeBTUCellTM will be useful in any dry soil, even with well water at 200 feet as we can, with this Feng System water furnace, create high elevation local water tables.
