Iceland Is Drilling a 3-Mile Hole to Tap Magma Power

They have tons of hot sulfurous water left over that needs to go somewhere, but you can't just dump it in the ocean or environmentalists would get all mad. And you can't dump it on the land because it'll leave this ugly white stain as the minerals leach out.
So they dump it all in to this big pool out by the airport and call it The Blue Hole and have busloads of tourists lining up waiting to pay $50 to swim in it. Genius.
One day somebody will figure out how to do this same trick with nuclear waste and we'll have our power needs sorted forever.
It's proximity to the airport makes it especially attractive to tourists who want to soak for a few hours in the middle of a transatlantic flight. Go there if you can; it's fun!

> As of December 1, 2015, there were 99 operating nuclear reactors at 61 nuclear power plants in the United States. The Fort Calhoun plant in Nebraska has one reactor with the smallest generating capacity of 479 megawatts (MW). The Palo Verde plant in Arizona has three reactors and has the largest combined generating capacity of about 3,937 MW.
Looking around a bit, I guess nuclear is considered cheaper than geothermal, but for Iceland the fixed costs of dealing with nuclear might be prohibitive (right now they spend nothing on stuff like securing nuclear materials, to add a gigawatt of nuclear, they have to deal with it for a long time, or pay someone else to do it).
So interestingly, even at Iceland's scale, this 50 MW additional capacity will amount to only 1% of their total installed capacity, which seems small.

All that cheap geothermal power is being used for energy intensive industry, like aluminum production. While one borehole of 50 MW is not huge on their scale, each bit of additional energy can go toward their industries.
Well, the best answer I can say is: we do it already. Every time we've drilled for fossil water (that's a thing actually), oil, gas, salt (yep, we drill for salt), typically you want to do it into a fault line, because natural resources tend to gather there after millions of years. The exact circumstances depend heavily on the geology of the area; which I can imagine, for this type of investment/project, they are studying it thoroughly.
Really there's hardly ever problems sucking stuff out, it's shoving stuff back in that occasionally causes problems. 'Saltwater' (That's the leftover stuff after you extract the resources from your oil/water emulsion) disposal wells in the Midwestern USA have been implicated it lubricating ancient faults and causing minor earthquakes. (Interesting side note, the Midwestern USA was a giant ocean and has massive layers of salt deposits really far into the earth).
The technology behind injection wells is actually quite fascinating... they have cement and steel casing around the production casing through an absurd about of rock until they're way past the point where the point where it has no hope of returning to the surface. However, we apparently can't make very good predictions about what they do to ancient faults, and the communication between producers is minimal because they don't want to spill their secrets. Nearly ever state has a commission that regulates the amount producers are allowed to both extract and inject, but occasionally we still have problems because the commissions lack the field flow analysis that are proprietary secrets for most producers.
And no, fracking does not cause earthquakes or causes surface damage, even when the highly regarded scientific research organization CNN tells you it does. Doing so would be counterproductive to the producer anyway: they'd lose the valuable fluids they were trying to extract.
Now I wonder if active regions are safer for this, since energy is released more often (vs stable regions that might have huge energy built up over a long time). Could be total BS though.
Its a turbulent system though, so any prediction is futile :D
Asking for a friend.
But, no, not again super villainy, not one day at a time. I will not use super villainy today, no matter what happens. I can do this. We can do this. Super villainy does not control me. I am moving forward right now.
https://en.wikipedia.org/wiki/Crack_in_the_World
`An international consortium of scientists, operating as Project Inner Space in Tanganyika, Africa, is trying to tap into the Earth's geothermal energy by drilling a very deep hole down to the Earth's core. The scientists are foiled by an extremely dense layer of material at the boundary between the two. To penetrate the barrier and reach the magma below, they intend to detonate an atomic device at the bottom of the hole.
The atomic device is used and Rampion's fears prove justified, as the crust of the Earth develops an enormous crack that progresses rapidly. Sorenson discovers that there was a huge reservoir of hydrogen underground, which turned the small conventional atomic explosion into a huge thermonuclear one that was millions of times more powerful. Another atomic device is used in the hope of stopping the crack, but it only reverses the crack's direction. Eventually the crack returns to its starting point at the test site, and a huge chunk of the planet outlined by the crack is expected to be thrown out into space. Sorenson remains at the underground control center to record the event despite pleas by his wife Maggie to evacuate with the rest of the project staff. She and Rampion barely escape in time to observe the fiery birth of a second moon. Its release stops the crack from further splitting the Earth.`

I mean - most people I asked were just thinking that atomic energy creates steam and that's all.
When I educated my family and friends that its not the case, and that radioactive after-material is put in boxes and stored on the oceans' floor with life expectancy of 25,000 years before it will start leaking, everyone was in shock how this has even been approved in the first place...
And honestly, who cares about a person 25k years from now? We can all just die now, or instead some explorer 25,000 years from now dies, assuming we didn't figure it out by then.
I'd rather cavemen left us with a dangerous storage area rather than destroy the entire atmosphere and ecosystem.
Yes, go ahead, folks. What could possible go wrong with drilling near fault lines?
Iceland is covered in huge freaking volcanos.
Are you worried about releasing the Ancient Ones or something?
