Another source of energy, which charges the atmosphere, is surface geothermal energy emitted by the earth. This Geothermal force, or GTF, moves the atmospheric gases in an equally unseen manner. We can see the power of GTFs when they lift a giant condor or a glider high into the sky. Geothermal forces can be measured based on their ability to do work. These units of energy which I will refer to as GTUs, Geothermal units, can be concentrated to move large turbines and produce horsepower and ele
