Why don't we start casting Lava to build homes Lava rock homes use to be a thing. Hawaii has a active and relatively calm volcano that has Lava flows. Thoghts.
CO2 is definitely odd stuff. Think the weirdest thing I've run into was when I was working as a mud logger my boss told me about an accident on a rig back in the 70's that he was working on. From what they could figure out they ran into an old lava tube that was totally filled with compressed liquid CO2. Shot out the entire drill string, blew out the blowout preventer, and sprayed liquid CO2 all over for a couple hours. I forget exactly where it was, but it was in the southwest desert in summer, and he said that a frozen rig sparkling with ice crystals in the ninety degree sunny day was the most surreal experience of his life. Man, I wish I could have seen that.
Sounds like a story to me.. at 1 atmosphere of pressure there can't be liquid CO2. In order to do that you are talking about Temps of -78⁰C or at least 5atm of pressure and the porosity of a lava tube would not contain that kind of pressure. It's a cool story even if it's fabricated
@@dhirmer Probably a mixture of CO2 and water, which would lower the vapor pressure and be more realistic to find in the ground. Plus he may not have actually hit the lava tube, just removed enough overburden that the pressurized mixture could finish it's own excavation
@@dhirmer Ever wondered how a fire extinguisher gets cold when used? If gases expand they drop in temperature. The reason being that the total heat energy remains the same while being spread out, causing the tempature to drop. So if the gas gets cold enough, it could become a liquid. (Note that heat energy and tempature are not the exact same thing)
"You venture into the darkness, and you never know what you might find. Glowworms, crystals, millions of sleeping bats, a horcrux, Grendel's mom." Nicely played.
Hank used to have a very persistent tic to bring up his hand to his glasses, he was fidgety. You'd think that with the progress he's made in SciShow, he woulda completely lost those, but he's actively suppressing. You can see it on his tiktok videos/personal channel, he still got them. Super interesting stuff!
8:01... I find this fastening. I would like to know more about the process of harvesting methane from the water and using it as fuel... I watched the entire video. But, I have to say. Around 22:57, my brain began to ache. I enjoyed this one. Thanks.
"... to be honest, they're a bunch of creepy looking weirdos, but I guess living in total isolation in darkness for millions of years will do that to you..." ROFL Love you guys!
This is what people mean when they say "The lake is going to turn over soon" -alluding to the processes that cause the CO2 on the bottom to bubble up to the top, causing the silt to rise and spread nutrients through the lake
Most often the mixing of the strata in lakes (overturns) are caused by changes in temperature, driven by seasonable temperature variation, not CO2 or other gases. The lakes mentioned in the video are extremely rare.
When lightning strikes it actually helps clean pollutants in the air so assuming everything wants to be balanced. I would say this is earths attempt to balance out that acidity
Is there a published experiment with different greenhouses with different gases demonstrating the measurable temperature differences they can have? I feel like this would settle the debate.
There are such studies, they were generally done within a few decades of 1900. You'd be well advised to look them up if you're interested, but in general you get two small glass enclosures, label which is which, take some initial measurements with normal air in both, designate one to be the reference object, change the atmosphere of the other at night, and record measurements of both internal & external weather (internal weather will usually just be gas composition, temperature, and maybe pressure). If you had clouds, drafts, etc., then you might occasionally need to duplicate an experiment.
I’ve never been so mad to finally totally understand pH. I HAVE A GEOLOGY DEGREE AND NO ONE TAUGHT US THAT. That makes it SO much easier to understand my Organic Geochemistry class from 5 years ago. 😤
Came to say this same thing, saw someone beat me to it by almost a year; ain't even mad, just glad to see someone else with the same sense of humor! 😂 *High five*!
15:50 So why not put a giant outdoor Marx generator tuned for the same impulse profile as natural lightning on a ship and go for a trip? That would be far better than a beaker of salt water and a 100kV HV power supply bought from eBay without the 9v battery. Still not quite as good as the real thing, but 200m- sparks are better than 2cm ones.
I love your productions! Your "water scorpion" is actually a Giant water bug, a true bug. Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs.
I think they used a Ground Penetrating Radar, or GPR. It's just a guess, but they do use those machines to map out underground caves and determine how much liquid, usually water, is in the area. So, it wouldn't surprise me if they did use it! Hope this helps!
We already did, Yay!!! That's what Geothermal Power Plants are for. There is some in Norway, Indonesia and several other countries with volcanoes. Its reliable, relatively cheap, might last a long time (some volcanoes remains dormant/no eruptions for centuries or more).
@@classydemongaming847 You don't need to have a metal that can survive the lava, just place the pipe near the depth where water could boil(100°C, most metal alloys can handle 5-20 times more than that, and with the water cooling it, it will almost last forever, minus the corrosive damage) and use the steam to move a generator/steam engine.
@@samuelruiz7377 True, but under current technology, Peltier Plate are very inefficient , steam engine do much better for less cost. And even if they want to build generator using peltier plate or something similar, it won't make sense to let the plate directly in contact with the lava or any direct heat since it would destroy those equipment easily, the most sensible way is to use water or similar heat transfer method to provide the heat(and cold) for the peltier plate in a controllable manner.
My favorite part of CO2 lakes.. industry is proposing putting our extra CO2 on the ocean floor where it'll become liquid.. and one quake away from disaster.
Hi @SciShow Why does the description speak to joining Michael Aranda.... when Hank Green covers the majority of the content... and Michael Aranda puts in a few transitions, and ancient content where his hair is like 6" Shorter?
That beaker co2 experiment seems like bad methodology. Surely the co2 bubbles would act as nucleation points for the simulated lightning, but ocean acidification doesn't cause co2 bubbles to rise from the bottom(except maybe a local event dissolving something somehow)
I can't remember if I checked out the paper when they originally posted that video or if it was pay-walled. Regardless I don't think the beakers were actively bubbling when they tried running a current through them in the actual experiment.
@@VariantAEC that's reassuring. I would expect they knew what they were doing, but the animation sure makes it out like they just started bubbling it with the power still on. Still, I'm not sure that's a good analogy to the straight diffusion of atmospheric CO2, I mean even if it got much worse, the seas are still going to be flat(like the earth trollolol) not carbonated like a soda.
They think CO2 is a very powerful molecule. In reality is heat and magma shaped Mt. Erebus, its main crater and lava lakes; The Movile Caves were shaped by water and most of the other things were shaped by other totally unrelated environmental factors with CO2 being a completely inconsequential feature that shows up around all of them.
i just realized how well written these vids are. the imagery helps so much to visualize and intellectualize what is occurring. the whole episode is written very logically and is easy to follow. i even get some of the physics vids :) and, of course, delivery is everything when it comes to understanding also. every one of you is great at voicing these lectures like actors need to do. i don’t know why i haven’t thought of this before. Oscars to everyone. 😋😊😻🌷🪻🌱
How many people think that chemosynyhsis is the most likely form of life in the universe. It's easy not to notice species buriedbunder crust. What if photosynthesis is an anomaly of earth?
Considering the salinity of oceanic water, I'd doubt that carbonic acid has much of a effect at all. Not saying it's benevolent, but acidification is a long stretch to link to lightning intensity. The destruction of coral will be much more significant. Just my opinion, though
The amount of life we have found that can exist without light or oxygen is astounding. Are their theories as to whether this sort of environment could support larger life and brains large enough to to support intelligence?
Economics. Collecting the Methane turned out to require not insignificant amounts of infrastructure. Given that factory farming is about cutting every cost possible (and getting subsidies to cover the rest) most don't even try. There are farms that do use this, thought. But the ones I've read about has been smaller ones that has gotten some kind of government subsidy to to it as an experiment/demonstrator. Effective greenhouse gas taxes would probably make it a lot more attractive.
If the moss can be that effective we might actually have to be careful about how much we use then... we're talking about something that started a whole entire cycle of global glaciations simultaneously. All glaciers have that upper age limit, as he said it was an entire greenhouse earth before that with tropical like poles. Also I hope opening that cave up won't cause atmospheric differences that would endanger that ecosystem. I understand that at least co² is slightly heavier than average air so that probably will stay mostly put, but hydrogen, at least elemental hydrogen, isn't... maybe they need to put an ecological preserving airlock on that...
What's the probability that someone could modify Azolla to survive in saltwater? If they could, and drop it way out in the ocean where it would be more calm (like maybe the garbage patch?) And just let it grow, would that help with our current CO2 problem?
@@ttun100 I noticed that too. I know the emphasis of the video is the scientific explanation behind the phenomenon but the thought of over a thousand people asphyxiating made me pause for a moment in sadness. I've just spent some time looking at photos of the aftermath of the Lake Nyos disaster on Getty Images and reading survivors accounts, it was truly a massive tragedy. I know that was an older video and Hank's presentation style was different/more exuberant but it does show how sentence intonation makes a big difference in how you convey information.
Why don't we cast Lava in blocks and use it to build 🤔. Lava rock homes use to be a thing. Hawaii has a active volcano thars relatively calm. Thoghts 🤔.
Beyond the fact that it would be so expensive it would be prohibitive, it is also nearly impossibly to get a steady supply of lava that is easily accessible. For example, only 5 consistent sights on earth where there is a lake of the stuff.
Just check out the weather satellite that has been taking the earth's temp since 1979 and see if you think there is really that much to worry about . We do need to clean up our act better , but plastic is a worse problem than climate .
