<p>The present invention provides a deep geothermal changer with improved thermal conductivity. Global warming is accelerated due to industrial development and the increased use of fossil fuel, and thus abnormal climate is intensified, which are proofs of that the earth struggles for the application. It brings calamity upon humanity. Countermeasures are required, and the present invention is developed to support the low-carbon green growth policy of Korea. The earth has thermal energy in the core of the earth beyond our imagination, and CO_2 can be reduced by utilizing the thermal energy in our lives. A more effective apparatus is required for transferring the thermal energy.</p> |
