Where does the energy come from?
Our Mother Earth is a sphere with a diameter of about 8,000 miles. Beginning just below the surface of the Earth, scientists have found that for the first several miles the temperature remains relatively constant (50° F throughout the northeast.) Below this, the temperature rises gradually to about 2200° F at a depth of about 100 miles. For the next 7,800 miles, the temperature rises from 2200° F to 7800° F at the center.
Our Mother Earth is absolutely packed with heat energy.
It only depends on man's ability to find safe and economical ways to extract and use it. Happily, this methodology has been found in the device called a Geothermal Heat Pump which allows us to tap the energy of the earth at the upper 50° F zone without having to deal with the much greater temperatures at the deeper levels.
