steam turns heat into motion, MOTION is what creates the electricity. Why do STEMcels have such a hard time understanding and accepting this?

Why don't we make pipelines made out of the same reactor material, and then transport the super hot fusion plasma around to peoples homes so that they can release some of it through the vents to use for heat?
>>
>>16859425
Oil exhaust gases are too spicy
>>
>>16859425
We already have nuclear fusion.
But the downside is that we only know how to do it when the components are extremely hot. Unfortunately to make Fusion happen we need the components to be so hot that we cannot control it. And so fusion is only really used in Nukes right now.
What we are still trying to figure out is called "Cold Fusion" so that we can control it and use it for energy too.
And obviously, cold fusion is just nuclear fusion that allegedly happens without the need to excessively heat up the fuel to a temperature extremely hot, and that way we can control it.
Lol.
>>
>>16859425
Just to clarify again.
Nuclear Fission is when you split an atom and this reaction has a great power-to-size ratio.
Nuclear Fusion is when you combine two atoms and this reaction also has a great power-to-size-ratio. But according to Wikipedia, it only happens at "millions of degrees of heat."
So Fusion is not really useful for energy, because you would need your Fusion powerplant to be millions of degrees hot for it to function. Fission does not have this requirement so nuclear energy plants use fission right now.

Cold fusion is just hypothetical and alleged and not confirmed to be a real thing, but it's the concept that you could maybe make fusion happen without your facility needing to operate at millions of degrees.
And I think it would be better than fission apparently if you could do that theoretically but nobody can yet.
Lol.

If people start fucking with the vacuum and zero point energy I'm afraid we'll fuck something up really really bad.
Like, couldn't we accidently create false vacuum decay and wipe out the entire universe if we start fiddling with that shit?
>>
>>16859821
Yes anon le entire universe is going to end, just like le entire atmosphere is going to ignite when le nukes explode, definitely don't research cheaper ways to produce energy
>>
>>16859821
They thought there was a remote chance that detonating the first nuke would cause a chain reaction across the entire atmosphere and incinerate the entire Earth planet but it didn’t stop them. Yolo

>>16859827
>one time they thought something bad would happen and then it didn't, so that means nothing bad will ever happen
I don't agree with this logic
>>
>>16859832
If the universe was so fragile a slightly intelligent monkey is able to end it with a bit of made up numbers then it wouldn't have ever existed in the first place. You're not questioning if people are able to contaminate the atmosphere a little bit for a brief moment, you're asking if using geothermal energy is going to split the world in half, utter nonsense

That’s fine but the monkeys will continue to delve into and fiddle with the fabric of the universe, results be damned.

Being mad at boiling water is supreme midwit territory. Once you've seen how shit other forms of energy generation works you'll keep coming back to water.

because we're born on a planet with a lot of FUCKING water.

Perhaps because, unlike me, you only know one language.
I can think of something just as good. I'm not promising you free endless energy, it would be a trap like a perpetual motion machine, but humanity can build and use thorium nuclear reactors. As far as I know, they are safer than uranium and plutonium ones. The explored and estimated resources of thorium in the world of the planet Earth are estimated at about 6-6.5 million tons. This should be enough for humanity until the year 40,000, and maybe even more.

They will likely eventually figure out a better way but as for now we've already made energy more important than food, shelter, and practically everything else because everything else is now harder to make than energy, but only because we've gotten so good at making energy and once you have energy then making everything else gets easier. Water is kind of the one exception still, as long as we're only talking about things humans need. But eventually we very well might get so efficient at making energy that the means to do so become even more foundational than having access to water.

The plasma needs to be guided by fuck huge magnets. If it touches the walls it instantly loses all energy. Not only because the plasma is super thin because those fusion reactors operate at high vacuum. You also need to constantly feed it fuel.
It's not something you just heat up and take away some excess energy.

Like 90% of the heat of the earth comes from nuclear fission in its core.

Genuine question:
What if instead of boiling water, we used boiling refrigerant to spin our turbines?
Like isn't the whole point of those that they evaporate and condense very clise to room temperature? So why not spin our turbines that way?
Is it a thermal expansion thing?

We can, and already are look into supercritical CO2 Brayton cycles, which use an alternative working fluid for significantly higher efficiency than the traditional steam cycle.

Antennas turn photons into an AC voltage. Anyone remember the national lab in like 2010 that printed microscopic antennas onto some Mylar with a layer of gold? They had like 98% conversion efficiency with infrared light. Problem was the frequency of the AC output voltage was too high to convert into usable DC voltage.

Because you can have desalinated seawater as a byproduct that helps with water shortages retard.

There is no better way. This is the best and most useful. We don't need another way.
>>
With DT fusion over 80% of the energy is carried by uncharged neutrons which need to be stopped by radiation shielding... so all that energy pretty much has to end up as heat.

If water feels too low-tek you could use helium or CO2 as a working fluid but power companies don't care how cool the working fluid is.
>>
>>16870476
It's the same problem with fuel cells, they have fuel cells that can run off of various fossil fuel gasses but boilers and gas turbines are almost as efficient and much cheaper
>>
>>16866700
because it creates pressure that can be directed to create motion
