Gyrotron Assisted Laser Drilling to Drill 12 Mile Deep Hole - Maybe
2025-03-10
Quaise Energy is planning to drill test holes up to 12.4 miles deep, using a 1-megawatt gyrotron that should zip through the rock in a mere 100 days. At these depths, the temperature will likely be around 932 degrees Fahrenheit, which is hot enough to provide a practical source of geothermal energy.

#7  Okay and how are they going to keep pressure in the wellbore? Mud? Filling it with Argon isn't going to keep out influxes of water, oil, etc.

#6  A gyrotron is a vacuum electronic device (VED) capable of generating coherent high-power electromagnetic radiation in the microwave, millimeter wave and terahertz band. It operates on stimulated cyclotron radiation of electrons gyrating in a strong magnetic field typically provided by a superconducting magnet.

1 Oops and a instant Super Volcano.

Wonder what it would do to the surrounding Underground water and wells.

#2  Prediction: they're going to find that lateral slip forces induced in the rock cause things to go sideways. Literally.
There's a lot of lateral 'squirt' the the rocks that deep.

#1  If they let out the methane the balloon will collapse.
