    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.

    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.

    But how could this be possible?

      Clearly, the lava is just the blood of the mountain and now it has enough lava blood flowing to achieve sentience and to access xitter.

      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.

      Now it’s just a dumb musktake.

    Better yet - use helicopters to drop chunks of icebergs into the volcano to extinguish it.

    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?

      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.

      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

        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.

        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”.

          When the price difference is big, it’s kind of, ‘oh well, have to be practical’, when the shitty solution is picked. When the price difference is small and the shitty solution still gets picked; that’s depressive. That is when governments need to incentivice the better solution; cause capitalism won’t.

      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.

          Nuclear reactors and geothermal power plants both simply boil water to push steam through a spinning turbine to make energy. That’s literally it. There’s no other way to utilize that heat in a safer or more efficient way.

          It just boil water to create steam to spin the turbine, too hot will harm the equipment quicker.

          Yes, they already been doing it, either close (but not too close) to volcano, or in a place where the earth crust is thinner(which is still near volcano), but never on the volcano itself. It’s one of the location specific renewable energy.

          Also we don’t just turn heat to electricity, we use heat to boil water to create steam to generate electricity, the source of heat is what different between power plant, like for example coal, incinerator, nuclear, and sunlight, all are just to boil water.

      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.

    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.

      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.”

        Not that I want to defend using duct tape for this, but fixing a tyre isn’t about keeping nails out but closing the hole after the last one.

        The picture is dumb as hell. The lava would just flow out of the big gaping vertical hole in the front.

      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.

        If it’s concrete i think it will just explode upon contact because of the water content.

        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.

      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.

    I feel like when the volcano does explode it’s just gonna launch that concrete plug like popping a pimple.

    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.
