  1. My guess is that the gyrotron is going to be inside the borehole a few or several meters above the melt zone to keep cool.

  2. The problem is that they do not exist (outside of military applications) and could not be transported that way without a MASSIVE security team as they run on near weapons grade plutonium or Uranium.

  3. There is always wind somewhere, hence why a strong transmission network is good to have. Storage is already being built, it is soon not an issue.

  4.  @JorenVaes  That is probably true, should be interesting to see if they can build a good enough wave guide, that sure seems like a potential downfall.

  5. They need clean optics and are easily disturbed by debris in the hole.

  6. @ Microwaves are less distrubed by it, and they can use a waveguide to have the emitter far away from the melt zone.

  7.  @lucaswatson1913  No, it is sealed and filled with nitrogen purge gas.

  8. As they can control the way it cools they should be able to control the fiber diameter, anything above 10 microns is considered to be safe with the use of normal masks. Asbestos is dangerous because it is all the same dangerous diameter, this would make a range of diameters, not all asbestos levels of dangerous.

  9. True, they will probably use a conventional drill rig to predrill the holes to something like 2 km

  10. Gas needs oxygen to burn...there is no oxygen in those...it would just make very hot gas, nothing dangerous. Besides, they are not drilling for gas, so they are drilling in totally different regions than gas rich places...

  11. A: Nitrogen/Argon purge gas through a internal extraction pipe B: No, it is rotating for the same reason drills are, to make a round hole, the drilled hole and the final hole is the same diameter. C: 1 MW, not much different compared to a normal drill rig.

  12. Well, that would require powerlines of a size never seen before. Oil can be transported with losses in the single digit %ages, the same cannot be said for long distance electricity transmission.

  13. Debris would obscure the light quickly...a borehole is not a clean enviroment.

  14.  @graemepennell  It is, but the wrong kind, better off using solar panels to power the Gyrotron instead.

  15.  @graemepennell  Transmitting that light down a hole to a depth of 9-20 km would loose almost all the light, and even then it would struggle to vaporize the rock, you would probably need 1-10 GW of light to do it, and only about 20% of the time there would be enough sun light to power it.

  16. Gas pockets rarely contain oxygen, so no, it would not explode.
