Out of curiosity, does anyone practice "soft" PMT (i.e. not based on 'hard science').

Ehe, technically I do, as my alternate canon is as mushy as can be, but I'm not even the most active member of it. My alternate canon is, nevertheless, decently developed, and I can certainly advise on matters pertaining to soft PMT.

[Haishan]

Of course. I presumed as much, but was merely clarifying. And yes, I am aware of the appeal of LOHCs and liquid hydrides as alternative methods for hydrogen storage to pressurization and/or cryogenic liquefaction, which was evident in my first post on the matter.

I apologise then for jumping into conclusions. However a general question comes into mind; would you prefer to combust the hydrogen or use PEM/SOFC for power? I imagine in PMT scene, integrated electric propulsion will become more prevalent thus favouring the development and usage of PEM/SOFC fuel cell. The US Army/Navy is currently investigating into such power source since the usual inefficient ICE could be eliminated and there wouldn't be much conversion equipment needed.

Kraven comes into mind with his breeding program and cyborg soldiers. There's also Dephire and his nano(?)-augmented soldier in a Gholgoth's RP. I've been writing (somewhat) PMT stuff but it's based on IRL research however. Still writing it.

Also a second general question; what do you guys think of LENR? NASA was gung-ho over it. By the way, as the word of the vine goes, LENR=/= cold fusion. Do not mix the two or terrible consequences (and connotation) appear, notwithstanding Andrea Rossi's fraud.

In Kaltorya's case, ICE is being used while the fuel cells and related technology is being developed while civilian use is already heard of. The cells will replace ICE in military fields sometime in the future.

I though PMT is near future and technology like teleportation is future technology.This resulted in my nation being an early FT but we haven't colonize any planet yet.Also to note is my nation is once MT before i changed it

There's this division in PMT, one of which the 'MT+10', in which the exciting but experimental things you read in the news becomes true (ETC guns, unmanned tanks, etc.) and the other one the 'softer' variant. The core essence though is how emerging technologies shape society and what road they lead it down to, for example in Nightmare Tech you've got all the dystopian elements.

Faster than light communication, non-localized communication can possibly be broken in strange ways with quantum entanglement. There are also questions of whether the speed of light can be increased or increased. I can see a PMT where messages but not large objects can propagate faster than light.

Wouldn't breaking faster-than-light speeds enable a massive FT technological propagation within a particular nation('s home planet)? Since such advancements will lead to massively upgraded supercomputers, and then...

No, you cannot transfer information faster than light despite having quantum entanglement due to non-communication theorem. The speed of light is absolute and even quantum entanglement obeys it; to entangle two objects you will be forced to rely on classical communication (i.e light particle) which means....non-faster-than-light communication.

To communicate and measure change...you need classical communication since measuring change involves telling the other guy what is the state of qubit A in contrast of qubit B held by the user. Faster-than-light communication, which is a subset of faster-than-light travel is purely FT.

I read these things and it seems that it is a matter of interpretation what faster than light speed actually is.

The article title is very sensationalist/obscure and misleading to believe; there is no explicit mention in the article that faster-than-light information transfer occurred. What does it tell however that they managed to entangle three qubits simultaneously which in turn mentioned the QSK which is for encryption. If it's indeed faster-than-light communication, words like "instantaneous" would appear and there wouldn't be any mention of 'nanoseconds' or seconds. Seems, perhaps, maybe...you know where do these leading words lead to. Faster-than-light communication, especially if it use the scales provided in article, would be instantaneous to observe.

That really depends on what sort of power can be put out by fuel cells. In my canon, electrical energy from advanced solid-state storage devices (far more gravimetrically and volumetrically dense than modern Lithium-Ion batteries) is used almost exclusively, and hydrogen combustion in only utilized in situations where electricity would otherwise be impractical (such as jets) or cannot produce the same force as combustion can.

I know too little on NASA's LENR project to really comment, though one method of LENR I have investigated as more of a far-PMT technology would be muon-catalyzed fusion. Basically, by replacing an atom's electrons with muons, one significantly decreases the repulsive force of electrons on each other, lowering the energy needed to fuse two atomic nuclei.

I'm backing Haishan on this. FTL technology has its refuge in vague wording and distant prognoses. Whatever the case, quantum entanglement cannot be used to communicate faster than the speed of light, due to the aforementioned non-communication theorem.

Have you read the S-MAGJET patent? Bring on superconducting, electrically-powered turbofan! S-MAGJET is way more than simply an electric turbofan though, the patent also claims usage of MHD. All sorts of 'wut', clearly PMT.

What about magneto-inertial fusion for spacecraft?

[Santheres]

Out of curiosity, does anyone practice "soft" PMT (i.e. not based on 'hard science').

Exclusively so. I do realism, and it is important to me, but realism does not necessitate hard science. I have concepts that are based in science, but I neither know nor care about the actual science behind them; only that they are cool, fit my national character, and are believable.

The science... well, I don't need a second job that doesn't actually pay. Or third, since I actually do have a second that doesn't. The narrative effect is far more interesting to me.

[Vistora]

Aye, that's what we use for our SSTO spaceplanes.

[Haishan]

Do you mean for propulsion or for power? If for propulsion, it's likely to work as per extension of VASMR drive but 90% for propulsion though. In my opinion, it would be somewhat middle PMT assuming current fusion research is to be used as a benchmark. Have a related link (2015) discussing state of 'hot' fusion research IRL.

Aye, that's what we use for our SSTO spaceplanes.

I was thinking to either use nuclear light bulb (NLB) or Orion for massive lift capacity. Both designs can be made like a flying brick (i.e incredibly strong for a spacecraft) but NLB is more challenging than Orion to engineer. The way I see it, to make space access worth while you need to make it cheap. To make it cheap, it's either you launch often or lift a lot or both. Otherwise the costs start ballooning quickly thus my decision to go nuclear lift off.

Haven't fully decided yet, but I think our spaceplanes use fusion nuclear-thermal rockets for exoatmospheric propulsion, as the only fusion reactors we have been able to miniaturize enough to fit on a reasonably-sized spaceplane are D-T fusion reactors.

[The Macabees]

An uncharacteristically short post on my part, but I decided to bring out some of my more 'soft' PMT ideas there.

An open question: how much do you all spend on energy?

[Vistora]

An open question: how much do you all spend on energy?

As far as fiscal policy goes? Our energy industry is privatized. Energy firms get building permit and charter priority if we're at risk of an energy deficit, but that's pretty much it.

[Haishan]

An open question: how much do you all spend on energy?

Let's modify the question befitting the theme of thread. What PMT power source you guys use?

---

I haven't thought of such, so my major power source would be liquid metal-cooled nuclear fission. Transportation use either very good batteries or synthetic diesel or both. I'm however have some interest to design a space-based solar power system to supplement the nuclear option.

Then I intend to go polywell fusion route for certain section of Haishan, slowly replacing the nuclear fission option in conjunction of the space solar. Nuclear fission power capability will be retained as some fission reactor designs produce useful material for atomic bombs. Speaking of atomic bomb, I have a PMT design of it.

Liquid metal-cooled? That's a component of the IFR's design, is it not? Considering your level of advancement, I would expect that the IFR would be within your purview.

We just use stellarator-style magnetic confinement D-T fusion for about 85% of our grid. The rest is wind, solar, and a few other renewable sources that exist moreso for research than power provision.

Yes, liquid metal-cooled reactors. Amongst the lines of FLiBe, IFR, fast neutron and such. I generally term it as liquid-metal cooled reactor considering different designs have different usages. A fast neutron design would be useful for a submarine but not so for civilian which demands separate requirements. If all, I chose liquid metal cooled-reactor for its safety benefit, i.e no Chernobyl meltdown for example. Then because generic liquid metal cooled reactors are perfectly MT (Alfa's reactor comes into mind and so is MSR Experiment).

My answer is in terms on telling a transitional phase considering the switch wouldn't happen immediately as tech progresses. There might be some old tech there and there as newer ones get introduced. As for level of advancement, I don't really classify Haishan to be measurable in such metrics or whatever since it's not useful to me.

As for tokamak so you went big risk, big power, big fusion eh. I bet on polywell fusor since it's several times cheaper than the lines of JET/ITER. Then there's also Lockheed Martin's CFR but its consistent operation feasibility is questionable for now.
