PowerTube Global

The Power Tube differs from standard geothermal power production substantially. Geothermal Power Plants are defined by the Energy Information Administration and NREL as using water or steam heated from the earth to drive a turbine either directly or indirectly. Geothermal is only mostly clean energy because of the ground chemicals released into the air. Few locations worldwide are ideal for this, as generating power from today's mainstream geothermal plants require: a) high temperature heat resource (usually 500 degrees or higher) b) access to large bodies of water, and c) a market which can support a production price of 5 cents per kilowatt-hour or more. Geothermal is also a mature industry, where most of the growth occurred by the late 1980's. The Argus A-1 unit does not rely on water to drive a turbine. Since it is completely enclosed, it releases no pollutants into the air.

Due to the significant differences between Argus and standard geothermal technologies, we have coined the term geomagmatic. Boiler: The boiler is a shell and tube heat exchanger used to convert the working fluid into a high temperature, high pressure vapor for inlet into the turbine. The working fluid is inside the tubes, enters the boiler as a liquid, and exits as a vapor. A heating fluid flows through the thermal riser up from the hot geothermal resource and enters the vertically oriented boiler on the shell side. The heating fluid is in intimate contact with the tubes.
