ACTUALLY ITS BOILING SODIUM!!… ~which then gets used to boil water~

[-] Akh@lemmy.world 141 points 5 months ago

I love that deep down, coal, gas, nuclear, this thing… all done to heat water, make steam, use steam to turn turbines…. We are just in a steampunk universe

[-] BC_viper@lemmy.world 88 points 5 months ago

Always has been.

[-] LurkingLuddite@piefed.social 70 points 5 months ago

Solar panel projects, which many have outstripped this and other projects in power limitations, do not boil water to generate electricity.

[-] lauha@lemmy.world 54 points 5 months ago

And wind turbines, and hydroelectric plants.

But all but solar cells are pretty much turbines all the way down

[-] ViatorOmnium@piefed.social 15 points 5 months ago

Hydroelectric power stations still rely on steam, it's just in another part of the cycle.

[-] ByteJunk@lemmy.world 18 points 5 months ago* (last edited 5 months ago)

What? Hydroelectric power stations use gravity and the falling or flowing water makes the turbines turn. No steam.

Thermal plants (nuclear, coal, gas), including solar thermal plants, use steam.

He means water vapour, ie the rain cycle.

Oh neat like the ones outside Vegas, I always wonder if birds fly into the center

[-] BluJay320@lemmy.blahaj.zone 121 points 5 months ago

Well they certainly don’t fly out of it

[-] ascend@lemmy.radio 11 points 5 months ago

The ones with cameras might, probably a big conspiracy

I love how fucking biased that article is. It mentions Obama like 10 times, including this gem:

Clearly, the Obama administration decided to spend taxpayer funds on a technology that was poorly conceived and quickly outdated.

Thanks for the hindsight, moron writer guy. So what's trump doing, investing in better renewables?

No, instead of building an underperforming power plant, he spent the same money just to prevent a power plant from being built.

Money for nothing and the chicks for free amirite.

Never sell proven chemistry or physics short. Water transforming to a vapor is awesome. Maybe we could harness the energy of water transforming to a solid too.

It's so crazy that we've found like six different ways to use rocks to boil water. You'd think there'd just be two or three

It's incredibly silly that even tho we advance the scale of power, with electricity, solar and even nuclear, all we use it is to boil water. We just can't seem to be able t build any a more advanced mechanism, it seems.

[-] starman2112@sh.itjust.works 24 points 5 months ago

Hard to beat spinning a magnet to generate electricity, and it's hard to beat boiling water to spin a magnet

I think this may be due to the specific heat of water, no other substance matches it.

Wind and photovoltaic have nothing to do with water

[-] apotheotic@beehaw.org 11 points 5 months ago

Mfw they use wind and photovoltaic energy to pump water to a high place so they can put it through a turbine later

Kickstart this new source of clean energy by burning fossil fuels and spraying CFCs into the air. A hotter planet means water boils easier! 😃

[-] Alcoholicorn@mander.xyz 18 points 5 months ago

The efficiency of any heat engine comes from the difference between hot and cold, you can't get useful work if the water's already boiled.

It turns out boiling water is a really good idea.

There are a lot of options, but water works, is cheap as hell, and spills aren't much of an issue.

Are we against boiling water only because it is old? Because if that is the only problem and we are ok with reliability and efficiency than i will take old

[-] Skullgrid@lemmy.world 16 points 5 months ago

It's more that when you look at history and technological progress, and our (millenial's) own view on technological progress, the current stagnation and the permeation of said stagnation is a pain point. Every time we look at the news, it's something going fucking wrong, and never delivering on the promise of a better , brighter future.

We saw computers go from 100s of Mhz to 3 ghz ish and just get fucking stuck there. From 16 meg to 64 gigs, and now we can't buy any ram. We had touch interfaces being able to show you an arbitary interface and instead of innovation, we got swiping through stupid videos. We look through the history we didn't live through, and see that in the 20th century, we went through flight and rockets to the fucking moon and then nothing. We have a rocket going to the moon with people in it again for the first time since the 70s, and they aren't even doing anything new, just flying around. We expected there to be fucking bases on MARS by the time we got to the distant year of TWO THOUSAND AND TWENTY SIX.

Even now, when we're coming to harvesting power from the sun, in a seemingly new way (focusing it with mirrors onto salt) it's just going to be the same shit, nothing new, no innovation. Just put the hot rock into water, and harvest it through steam power as if it's the fucking 1800s.

Also, it has a light relation to the evolution inevitably creating crabs once again meme of Carcinisation.

Physicists just looove a hot shower

That's the reason why all electricity generation boils down to hot water.

[-] snugglesthefalse@sh.itjust.works 11 points 5 months ago

Well molten salt batteries are a thing, I'm presuming this is to buffer the output of the solar and that the losses were deemed acceptable given the renewable nature of this.

fun fact, u can also boil opposed spy satelites with that setup

[-] Agent641@lemmy.world 20 points 5 months ago* (last edited 5 months ago)

I doubt it, calibrating a focal point to a stationary, relatively nearby target, say a hundred metres or so, is fairly simple, but to apply that to a satellite, a moving target (with a changing velocity if we are talking about a satellite in an eccentric or molnya orbit) either in high or low earth orbit, that's a distance of between 200-20,000kms.

Even a satellite in perfectly circular orbit is constantly changing its distance relative to a point on the ground, meaning you have to constantly adjust the focal point of the mirrors. At 250km, your field of mirrors (say, a 100m circle of them) would describe about 0.023 degrees of curvature, almost completely flat.

And that's before accounting for atmospheric attenuation and scattering of the light.

On a clear night with many gw of laser energy, maybe you could peel the skin off a low orbit satellite, but even that would be impractical.
