Drilling engineer here Sub surface is not all rocks rather its a uncertain combination of various things such as brine, crude oil, natural gas, salt dome etc. The pressure of all these is extremely high and is balanced by Mud. So in lab its easy to vaporize a rock, but doing so in High pressure high temperature environment will bring serious challenges. The soggyness of rock at a depth of 10-11 km will bring further make it difficult to drill deeper. Lets see what they do..

I work with gyrotrons. A 1MW gyrotron, with the typical efficiency of around 35 to 45%, depending if you're using or not a depressed collector, needs more than 2MW electrical power. Yes, more than 1MW is "wasted" and goes into the collector. By the way, electrons start spinning the moment they leave the emitter, the magnetic field isn't negligible in that region. I don't know how Quaise can put some much power without being in vacuum, normally you end up ionising the atmosphere and create a plasma which then tends to reflect the power. I hope they figure it all out, there's so much energy down there to be exploited, it would be a blessing for humanity and the planet.

9:31 You know for a fact they started saying “ROP” not because it was faster to say, but because they couldn’t stop making jokes about the “Rate of Penetration”

1:07 Small correction! There are no sustained nuclear fission reactions occurring in Earth's core. It is the radioactive decay of certain elements that contribute to most of the heat at the core.

Hi! Pessimist here. The deeper they drill, the more rock fragment / vapor will need to be carried out by the purge gas (volume = depth x pi r^2). Eventually "rock vapor" may cool down + condense on its way up and block and drill hole, or the total mass flow of the fragments-in-transit will exceed some mechanical limits of the purge gas system. They can't realistically maintain the same ROP. Cool technology transfer from fusion research though.

Back in the 60s, General Dynamics came up with the “Blowtorch” system. It used combustion not to melt the rock, but to break it up by sputtering at the rock’s natural frequency. It worked but for one thing..the vibrations welded the pipe joints together.
General Dynamics teamed with Gardner Denver which made blasthole drill rigs. I heard the story about it second hand while working at Gardner Denver. Perhaps a patent search might turn something up.
Marble Falls, Texas sits on solid granite. If they can drill there, they can drill anywhere.

I really like the visual of the earth's cross-section as a little crucible. It's a small detail but it looks nice. The whole diorama aesthetic works pretty well for this sort of content
@samg9908
I like how you let the guy ramble about the technical parameters that they are working with in the research. Its great to hear the guts of the work
@ArbitraryConstant
1:08 it's not fission in the sense of a chain reaction, it's just radioactive decay
@jakobmax3299
Seeing Sci-Fi levels of technology that might actually become practical is just so incredibly cool.

Were sending you in deep so be on gaurd. Scanners detect particularly rich veins of Morkite and Gold further down. Bring it back boys.

In Perth, Western Australia, almost every single public pool is heated by geothermal power. Remember: Australia loves swimming, so that is a lot of pools. The University of Western Australia even runs their air-conditioning on geothermal power using lithium salts. Lithium salts have a special enthalpy situation and is a bit more complicated than you may think.

5:08 You say higher frequency radiation, but microwaves are at a lower frequency compared to visible light.
@Chainsaw-ASMR
This is one of those videos where Brian does an infomercial for a company making incredible claims about their new technology. Thankfully the comment section seems to be doing a great job of fact checking these claims and doing basic proofreading that the editor missed (like a fission-powered core).

19:27 Sounds like you’re assuming none of the drill equipment is reusable. Why wouldn’t they be able to drill multiple wells with the same equipment?
