While attending the GreenBuild 2012 convention in San Francisco I had the opportunity to spend some time at the Geo Power Systems exhibit. I found the technology very interesting. Geothermal systems are gaining more attention and implementation as the “Voodoo” of the technology is better understood. Geo Power Systems takes a different approach to geothermal that could be an attractive alternative to drilling down several hundred feet. They state:
“There are two kinds of geothermal or underground heat. One has its source within the Earth; the other derives from the sun. The Geo Power System utilizes the underground heat from the sun. The sun radiation energy is slowly absorbed into the ground, creating a temperature difference between the underground and the outside air. This temperature difference is why you feel well water or the air in a cave warm in the winter and cool in the summer.
It take the energy from the sun about half a year to penetrate down to a depth of 16 feet. This means that the underground temperature at 16 feet is slightly lower than the average during the summer and slightly higher than average during the winter. Geo Power Systems makes use of the temperature difference between the outside air and the underground temperature at a depth of 16 feet. This difference can reach a peak of 30 degrees F.”
Geo Power Systems has recently completed their first USA installation in Poway, California. Click HERE to learn more about the renovation of the Poway Villas apartment community and how the Geo Power System was incorporated.
