There is clearly something wrong with our current format of energy generation, whether that is electrical, thermal, or kinetic forms.

What is the solution for this and why is it nuclear power?

>> No.14954494

nuclear is the most energy dense but still relies on cooking water for steam to run a turbine
most interesting news i've heard is a fusion "reactor" that generates electricity directly from the magnetic pulses, skipping the water cooking part

Aren't there gas or molten salt cooled reactors?
Could easily do a combined cycle with other working fluids (like steam) and extract more energy out of the reactor

Gas is bad at transferring heat but there are molten salt reactors that heat a secondary system that contains distilled water. Water is much easier to work with when designing and building a turbine. It's cheap and safe and the thermodynamic properties are very well known.
>Could easily do a combined cycle with other working fluids (like steam) and extract more energy out of the reactor
That is exactly what some already do.

I've heard that pressurised Helium or supercritical CO2 are potential fluids that offer better heat transfer.
Though as you say, most gases aren't good at convecting heat due to their low densities, among other physical properties.

There's definitely more efficient coolants, but water has the cheap+safe+established properties trifecta.
>Though as you say, most gases aren't good at convecting heat due to their low densities, among other physical properties.
The systems are kept pressurized to many atmospheres so the coolant stays a liquid. Water in the reactor core is usually several hundred degrees C, but it's a liquid because of very high pressure.

That's how all "electricity" is "generated" yes. You still need the geomanced copper archform though that has absolutely no correlation/causal link to whatever the fuck it is you're wasting at the burn site.

Fission has been too hamstrung.
It will be solar and some natural gas until someone makes a scalable and cheap energy storage method, at which point it will become pretty much just solar.
Eventually fusion will come around and once it matures it will become the primary energy source for all grid-scale things due to it being objectively superior.

>> No.14955614

>>14955600
Why not attempt to educate people on modern fission reactors? Or somehow lobby the govt to increase fission funding. Neither of these things are easy but they should at least be theoretically doable. It would be a shame if we used so much natural gas when we could have been splitting atoms.

>> No.14955690

>>14955614
They are doable, yes, but not feasibly. Not only are you still working against the forces that resulted in where we are today, but you're also working to undo decades of entrenchment. It would take too long, cost too much, and be too late. Even assuming you were successful, by the time you manage to just get the laws and opinions changed solar and energy storage will have advanced even farther, and fusion will be even closer.

Fine. The main problem was panic-buying gas by idiot governments instead of coordinating things and brokering good deals instead of outbidding each other as fast as possible. Now that the storages are all full the price is low again.
Nuclear is still the best deal to bridge into the future though, since "cheap energy storage" is more like 50 years in the future rather than 5

Cunt how tf are you supposed to charge a lithium car battery off a coal fire power station when there are literally not enough joules in the entire world-land for that to be possible simply - because you have requested an impossible situation. Switch to nuclear perhaps? Hmm OK then...

Yeah it definitely isn't ideal. But people here are already preaching Doom for the coming winter and make new gas deals with yet-another-autocracy. We have daycares who prepare kids with blackout drills, wich seems absurd to me who works in energy supply. Our worst expectation is (yet again) stupidity: people buying mobile electrical heaters in masses because they are afraid of their gasbill.

>Aren't there gas or molten salt cooled reactors?
only on paper, so far.
lead-bismuth eutectic cooled fast reactors were used on Alfa-class submarines.
it has relatively low melting point (~130°C) and boils around 1600°C, so you can transfer the heat extremely efficiently.
plus the coolant acts as radiation shielding and there's no great pressure involved in the reactor, so it cannot explode/rapture from overheating like PWR.

You may ask, what happens if lead leaks or solidifies in pipe? Wouldn't it damage the coolant lines and reactor?
To which I'd point out that Akula-class and every other Soviet/Russian sub since had conventional water cooled reactors.

They don't even know if it's theoretically possible, they're still a few $Trillion away from knowing if it's possible.

The main problem is BigOil is in charge of everything related to "Energy". And the grifting ''scientists'' love that, because it means they can just get $Billions to perpetually LARP about "2 more weeks until we have unlimited Nuclear! Don't worry about the fact that energy prices are doubling every year, this is just how science works! 2 more weeks, promise!"

Reminder: we could have clean, unlimited energy generators by now; we could even start building them right now if we wanted.

But no one actually cares.
It's more fun to talk about freezing to death, and arguing over "le nuclear power", instead of actually discussing cheap, practical solutions.
