Would spraying the area down with fire houses, just throwing all the water they got at the lava, maybe slow it down a little?

pretty sure the water would just evaporate with very little effect at all on the 700-1200c surface temperature of lava

Not lava, but similar scenario. quote:On 20 July 1981, 24-year-old David Allen Kirwan from La Cañada, California, was driving through Yellowstone’s Fountain Paint Pot thermal area with his friend Ronald Ratliff and Ratliff’s dog Moosie. At about 1:00 P.M. they parked their truck to get out and take a closer look at the hot springs; Moosie escaped from the truck, ran towards nearby Celestine Pool (a thermal spring whose water temperature has been measured at over 200°), jumped in, and began yelping.

That inspired some curiosity, and I'm having some nostalgia for my Uni days, so I looked up some numbers: Specific heat (kJ/kgK), rounded to two sig figs of: H2O: 4.2 Steam: 2.0 lava: .84 And the latent heat of vaporization of water is 2.2 MJ/kg. For every litre of 25C water you chuck at the lava, that boils off at 200C steam, you take away how much temp? I forgot I needed to know the latent heat for solidifying lava, since that's the goal, to stop it flowing. First loving google hit brings this, which is all the work done. God loving damnit. tldr: 250+ litres of water to cool a kg of lava down. Those lava flows are big&heavy, so no, not viable.

It... can be done (on a limited scale) once the lava gets close enough for you to make direct use of seawater. You need enormous pumps though. https://pubs.usgs.gov/of/1997/of97-724/methods.html

The goal isn’t to solidify all the lava, it’s to form a levee of solid rock that forces to rest of the lava to go somewhere preferable.

Memento posted:This is a thought experiment I came up with* to run with some 2nd year geoscience students who had just had a semester of igneous petrology and volcanism. "Why can't we drill into the side of a volcano to let the pressure out so that instead of a catastrophic eruption, we get a controlled release of pressure?" why couldn't you poke a few tiny holes into the part of the chamber that has gas (assuming it's not literally 100% magma), and run some turbines off the high pressure gas that comes out? You might even be able to burn it afterwards to get even more power! Exactly like slightly cracking the seal on a soda bottle and using that pressure to spin a little generator, except big! Tons of free safe energy! I think this can work fine, you just need a quick release so everyone can book it with the equipment in case the mountain gets grumpy.

Yawgmoth posted:You made me look this up and now everyone must suffer this link: https://en.wikipedia.org/wiki/Sharknado_(film_series) Completely off topic for this thread, but Dolph Lundgren was in the running to play Cable in Deadpool 2. He didn't get it, but, they wrote a character that hits all of the same main plot points (son of a main character, thrown into the grimdark future, comes back to the present as a grizzled old man with lots of guns) for Sharknado 6, played by Dolph Lundgren. If at first you don't succeed, just do the same thing in a SyFy Original movie with the serial numbers filed off.

Yeah, except spacex is held to standards that are uh conspicuously absent from say, car manufacturers. You may think "oh they'll cut corners" but satellite manufacturers, NASA and DoD spend billions on their launch payloads (and certification processes) and there is no loving way they'll launch on hardware and software that isn't held to the same level of rigor. Their entire business model depends on it and the commercial entities that partner with them would be absolutely certain about this before they'd ever contract them.
