Around the world geothermal hot spots have been identified as having the potential to serve the demand for electricity without creating more carbon emissions. In the past, these have been few in number and far away from where the demand has been.
Current geothermal technologies use the earth’s natural heat to drive turbines. These take up to five years to construct, and the moving parts increase maintenance costs.
Solid State TEG generation with an initiation temperature of 100ºF expands the areas accessible to geothermal production. Existing well data indicates that 80% of the country can now have geothermal power.This same data eliminates the need for expensive exploration and indicates most sites are already on the grid negating the high costs of transmission lines and permits.
The above topology chart shows heat at three miles down. Black, yellow and gray show the breadth of areas that can take advantage of Berken's GTV™ technology.
The application of this patent-pending, cost-effective technology demonstrates a multitude of advantages over current geothermal generation technologies:
Availability of Oil and Gas Drilling Sites
There are many limitations with geothermal technology. Not only is sufficient heat available in very few locations, but most qualified areas (e.g. Western States, Alaska and Hawaii) are already in use or off-limits.
Other limitations include:
The Future — Now
Berken's GeoThermoVoltaic (GTV™) largely eliminates these limitations by providing a robust technology that has several advantages to conventional geothermal. Laboratory testing has shown that the initial power generation begins at 50°C with peak commercial viability output beginning and continuing upwards of 80°C. This opens up a whole new realm for making geothermal energy the predominant source of electricity in the United States. World potential is unlimited.

It's true that conventional geothermal is efficient; however, most geothermal sites are already in use or off-limits due to environmental protection laws. That's where we come in: there are thousands of oil and gas wells already drilled and abandoned that can be upgraded for GTV™ applications!
How much energy can GTV™ produce?
Current samples are producing 150 watts per square foot. Developments are underway to improve that further.
