Redpill me on geothermal
>>108774470hot make steam, steam make power, power gud
>>108774470You need really hot water to generate power at any efficiency. Massive capex. District heating is much more feasible.
>>108774470>Redpill me on geothermalno
>>108774470like everything else its boil water to turn turbine
Wouldn't it in a larger scale cool down the core way faster?
>>108774489tap into some of the free yellowstone energy
>>108774470i heard it has major geographical constraints, hence why iceland can spam it but most countries can't
>>108774545Yes but that's a scale so astronomical you'd be dead from cooking the planet long before you'd be dead from heating it
>>108774745>i heard it has major geographical constraints, hence why iceland can spam it but most countries can'tyou can do it pretty much anywhere, you just have to dig way deeper most places which is expensive. There's some new tech that could make it cheaper, but it's not proven yet
>>108774470>geothermal powerplant>look inside>boiling waterEvery time.
>>108775399>Every time.not for long, soon it's going to be supercritical CO2
>>108775373Do you need to dig deeper to access convection currents? Am I right to guess that if you go too shallow, then your heat source doesn't renew itself quickly and your plant shuts down after a few decades due to the underground getting cold?
>>108775399internal combustion engines skip the boiling water
- small output numbers- have to live near volcano
>>108775399>>108774535So what?
>>108774470drilling Yellowstone is America's answer
>>108774535>what is freon
Can i drink this water? How does it taste like?
>>108774470Only works near volcanoes or future volcanoes.
>>108774470>boiling water againi am tired boss
>>108775782You need to dig super fucking deep and adjacent to either active or dormant volcanoes to get access to the kind of heat that can reliably generate geothermal power. The way heat underground works is that you have basically a huge convection of magma that swirls around and moves the earth. We can't reasonably access this convection though because it's way too deep. The best we can do on continents is drill near volcanoes and hope we get close enough to the magma chamber. The only reason why Iceland can do it is because they're positioned on a divergent boundary where the earth is splitting apart and spewing magma up from the mantle so they don't have to dig deep to get the heat. Drilling tech has come a long way, but reliably and safely drilling at an affordable cost that deep on continents is still going to take a long while. For the time being geothermal is virtually Iceland exclusive.
>>108777313I seeI suppose we can break through the crust in the ocean where the mantle is only 10km deep, but I guess transmission losses makes it totally not worth itShame the regular land crust is 30km thick
And damn the fault lines hug the border of the landmasses rather than bisecting them.Perhaps new zealand can do geothermal as well.
>>108776487>How does it taste like?Eggy farts & rust.Vulcanic activity is virtually synonymously with sulfurous compounds and iron oxide.Natural vulcanic water is essentially a sulfurous rusty soda.
