This is a very clear distillation of the absolute lack of imagination that is endemic across the National Parks Service. It is this mindset that stagnating progress in the National Parks. 105 years and there have been no major developments in Parks technologies. No waterfalls running in reverse, no water-skiing bison, no Grander Canyon. /s

Water skiing bisons, now thats a good idea

Kind of a water buffalo rip off

"PSA: Before drilling into a supervolcano magma chamber, please arrange to accept and dispose of at least 1000 cubic miles of superheated lava to be emitted at a flow rate of up to 1 cubic mile per hour. Thank you for your attention to this detail."

Yep- a rapid pressure release where the outlet is the surface of the earth is pretty much indistinguishable from a normal unplanned eruption. With, as a comment in the post suggested, a nice dose of nuclear fallout in the mix.

I imagine it escaped as a gas.

It escapes . . . as a gas . . . in an already highly pressurized environment . . . that is already containing a large amount of high-pressure hydrogen sulfide that cannot escape as it is? I'm pressing X to doubt.

That just means you need a second nuke to blow a hole that allows the gas to escape & lave to flow in, and a 3rd nuke to collapse the hole before the lava gets too far. It's all there in my book, "How to nuke your way out of any problem"

You could just create another bigger void and let the stuff vent into that

They tried that in the excellent documentary The Core (2003) but as I recall they didn't all survive.

However a separate documentary (Armageddon, 1998) illustrated the successful use of nuclear devices on objects of a seemingly intractable scale with extremely few casualties. The makers of the documentary also chose an excellent score to accompany their organic capture of a moving love story along with the antics of a plucky group of misfits that came together in a crisis. It's the sort of thing you can only shake yo…

You just can't make this stuff up!

One thing not considered in TFA is the idea of drilling a hole and then using nuclear explosions to pulverize the surrounding rock to effectively increase the size of the hole. This might also punch through the last (how many?) meters of rock that are too hot to drill through. I still doubt it would work, and if it did that might be really bad too.

Both Cold War superpowers considered some variant of using nuclear weaponry for subterranean engineering in their "peaceful atom" projects. For example soviets actually used a nuke to put out a gas well fire: https://interestingengineering.com/soviet-engineers-detonate...

Yep, the US had a program called "Project Plowshares" dedicated to their use in, primarily, construction: https://en.wikipedia.org/wiki/Project_Plowshare

Also if you apply hydraulic equations to the lave through such a small diameter borehole, you quickly find that you would NOT be in control of anything and you'd probably do more to trigger a large eruption - the velocity of lava out of such a borehole would be hypersonic at least and quickly open the borehole to form a new vent equal to an actual eruption.

This could be used as an assist to space maybe :) sustainable Earth based lava launches

I'm not sure if that would be better or worse than Project Orion https://en.wikipedia.org/wiki/Project_Orion_(nuclear_propuls...

If we are going down that rabbit hole, I love the plan to create an artificial Martian magnetosphere by placing a magnetic field generating satellite between mars and the solar winds. Generating an atmosphere on mars is all well and good, but it will just blow away again without some protection. The generator would only require roughly 583.9 exajoules, or roughly the world's total energy consumption in 2020. https://…

A superconducting tape girdling the planet's equator would suffice, and require after startup only the power needed to keep it chilled at all times below 70K.

That sounds actually quite practical and like an amazing option! Are there papers about this you could please share the links to?

The quiet-part-out-loudness of naming a project designed as a propaganda measure to leverage peaceful applications of nuclear technology (including explosions) to build acceptance of (/ mitigate opposition to) nuclear weaponry qua weaponry so as to invoke Joel 3:9-10 (“Proclaim ye this among the Gentiles; Prepare war, wake up the mighty men, let all the men of war draw near; let them come up: / Beat your plowshares into swords and your pruninghooks into spears: let the weak say, I am strong”) is, well, pretty amazing.
