And as a different politician I can assure you that if you vote for me I will fight for the freedom of volcanoes to erupt whenever and wherever they want. In fact, I promise a volcano in every household and quicksand in every sandbox.
Cause this is America. Where land has more rights than people voting.
Very rough Google math (mostly because of "fuzzy" answers on the energy required and how you define space) suggests that the 1980 Mt St Helens eruption had enough energy to orbit three billion kilos...
I based that on the eruption being rated at 24MT, which converts to 100b MJ, and a minimum of 30MJ/kg being enough for orbit. Didn't find a straight answer on escaping the gravity well, could be way higher.
That doesn't seem right to me, but that eruption did, in fact, move the entire top of a mountain a pretty silly distance, so as ridiculous as it sounds, it could be accurate? I mean... 500 billion KGs of ash was spit out of it...
That's the most terrifying thing I've ever googled i think. I feel like I don't actually want to know the actual math on this. It's fucking plausible dude.
That lava already has to break through literal kilometres of rock to get there. A few hundred (let’s be generous) extra meters of pourable rock ain’t gonna do shit.
I think we can still work with the spirit of the solution. The main issue is that the lava will break the concrete. The solution is pretty simple. If we take some buckets of water we can pour it into the volcano creating a layer of obsidian. Obsidian is much harder and will easily contain the magma.
Not to mention the average normal size of an opening you’d have to plug to begin with. Even if it didn’t just drain down the hole or dissolve the moment it got to lava, it would be a ludicrous amount of concrete just to make a layer a few feet thick. Even if you did manage to make a plug a hundred or more feet deep and it didn’t melt or move, an eruption would likely just blow the mountain apart from around it.
All you'd need is ultra fast drying lava-proof concrete. I'm surprised no one has thought of that yet. Then once the crater vent is fully plugged you would just need to coat the rest of the mountain in the same concrete. Voila, problem solved.
Or as the guy at bike shop put it "no you can't put duct tape on your pierced tyre. If a nail got through rubber, its probably gonna also get through tape."
I saw people on YouTube pour the cement directly into a hole they were filling. Should make it even quicker to not have to add water it can just mix with the molten rock.
I think this could actually be someone impersonating a famous mountain on Twitter, however, the account is verified with a Blue Checkmark, so this must be the real Mt. St. Helens then.
Even before twitter introduced these fake verifications, some large landmarks were verified by the managing party (like a national park), so if this were older that could've been the explanation.
Most cements melt at a higher temperature than most lava gets to, so it would be solid chunks of cement getting blasted miles out when the pressure builds high enough to erupt
Tens of thousands of tons of rapidly fragmenting concrete being launched into the upper atmosphere - cos what a major volcanic eruption needs is extra shrapnel
It's concrete, not cement. Cement does fuck all without water, aggregate and sand. Don't forget your tensile strength in rebar. It's like calling ketchup tomatoes.
Even still best case scenario would be like a pimple popping internally. There's still something going on below the surface that is not good.
But there would not be that best case scenario with a volcano. It's gonna blow if it wants to blow. Bonus: flying shards of concrete to compound the death and disaster all around.
I remember reading an article discussing the difficulties of re-directing a lava flow. One thing they mentioned was they tried dropping concrete blocks into or in front of the flow, and the concrete just floated on the lava.
Does remind me of my ongoing question of why we aren't using volcanoes as generators for geothermal power.
Apparently it can be implemented in a way that deliberately draws heat away from the source that's being used for the power, so why not just stick cooling rods into volcanos and then get free electricity courtesy of the earth being a hot pocket?
Because the electricity wouldn't be free, you'd have to build a ton of expensive infrastructure in the middle of nowhere (people tend not to live near active volcanoes), in an area that is very geologically active (cos of the volcano) with a real risk that everything you've built gets wiped out at some point in the next few decades (volcano).
There are a ton of ways to generate clean electricity, the trick is doing it in a way that is even remotely cost effective $/MWh
Your comment is of course completely accurate. The last paragraph is depressing though, "we have all the solutions, but we won't do them because money".
People absolutely live near active volcanoes. They have some of the just fertile soil on the planet. Naples, Sicily, Hawaii, Iceland, Japan, Indonesia etc. In fact Iceland is almost entirely powered by geothermal energy.
Geothermal use steam to generate power tho, and active volcanoes is quite risky to build a high cost power plant because we wouldn't know when it will erupt. Also active volcanoes might be too hot for the job.
How hot is too hot tho? Doesn't more hot just mean more energy?
Also, could you locate the electricity generating parts away from the volcano itself and just conduct the heat from the hotzone itself far enough away to still draw the heat out of the system without posing an infrastructure risk to the system?
I really wonder about the potential to basically turn volcanic hot zones into batteries and just suck the excess heat energy that makes them dangerous out of them. It seems like the biggest untapped source of power we have at our disposal next to the sun and all the forces it drives.
In the volcano that's about to erupt, there is a geothermal power plant right next to it. Same for the similar eruption in Hawaii, it had a geothermal plant already.
