Potential NASA Commercial Applications: Non-NASA applications include measuring of heat flow in areas on earth, where optimal thermal isolation of heaters/temperature sensors is of paramount importance. These for example include areas with hydrocarbon potential. Therefore exploration companies, such as Shell or Chevron, would in particular be interested in this technology. Since these heat probes are small and can be made relatively cheaply, they can be left in earth forever. Thus, the heat flow data can be accumulated all the time. This in particular would be important for tracking global climate change and to understand the nature and causes of climate change. Thus, proposed heat flow deployment method, because of potential cost savings, may allow more heat flow probes being deployed around the earth. The possible 'customer' may for example be the International Heat Flow Commission of IASPEI, who initiated the project "Global Database of Borehole Temperatures and Climate Reconstructions".
