Microtunneling AVN 2000.wmv

Very interesting video, I am wondering how deep can this machine go? Interested in going for Geothermal heat in the ground. For every killometer of depth we can get 25c boiling water for steam is 100c. I would like to go to 1000c and use liquified salt for heat transfer median, to bring to the surface in primary loop. Then secondary loops of supercrytical liquid such as CO2 to run turbines for electricity and the leftover heat to desalinate water, make diesel from coal and fertilizer.

this video is top!
