> There's nothing more revolutionary than a discovery of a new class of materials. After all, we often name eras throughout our history after them :) (Stone age, etc) I wonder what was involved in the discovery of stone.
I think the Ice age came before the stone age - can't imagine those tools lasted very long - so Stone tools would have been a big advance :-)

As far as I understand it (not an expert on these things), flux pinning is caused by microscopic defects that allow the magnetic field to penetrate at certain points. An idealized superconductor that is perfectly uniform expels the magnetic field at all points and so would not display the effect, it would simply be diamagnetic. So it’s mistaken and somewhat perverse to view the absence of flux pinning as proof that s…
No defects needed for flux penetration in a type-II superconductor. When the conference length is smaller than the penetration depth (up to a factor of sqrt(2)), flux vortices can nucleate as soon as the surface magnetic field gets above the lower critical field Bc1.

How would you construct such a knowledge barrier? Another prediction market? Also, suggesting that there is such a thing as 'smart' money - presumably due to having more of it? - is amusing. As pointed out elsewhere in this discussion, there has been a lot of smart money acting particularly dumb over the last few years.
A "Do you understand what superconductivity is?" or "Do you have a physics or engineering degree?" barrier? And the relevant question isn't whether 'smart' money does dumb things: it's whether 'smart' money does dumb things less frequently than a random sample of money. No one is an oracle, and there are absolutely outlier events that specifically confound experts, but I can't believe that increased expertise is unco…

Look, call 35K cold if you want. It's relatively easy to make some fusion at home [1] at even colder temperatures. However, the real issue here is __producing__ energy (edit: more than you put in). This has never been done in a sustained way (H-bombs produce net energy, there were some promising inertial confinement and tokamak results recently, but never for sustained periods of time). And in the chain, it's pointed…
I am old enough to remember "The Storm in a Glass". Back then, there was a discussion about excessive heat, because the scientific community doubted the possibility of nuclear fusion reactions at such low temperatures and energy costs. My own hypotheses were: a) the reaction is caused by cosmic radiation (muons), and the deuterium filled lattice only amplifies natural high-energy cosmic radiation; b) the reaction occ…
That's not how this works. Why do you think it can?
It is interesting to see how much of the replication is done by the Chinese and how little is done by the Western countries. Is this the difference between the making-stuff-happen attitude and the sclerotic attitude?

Although the plasma cutter creates extremely hot flames, it operates at room temperature and does not require powerful radiation protection, except for protective goggles, and it is easy to turn on and off. This sets it apart from the blast furnace. Similarly, a cold reactor may require a source of high-energy particles with very high temperatures to start, but they operate at room temperature, are easily turned on a…
Can you explain why you continue to say things that make no sense after it has been pointed out to you multiple times by multiple people? It's a bit strange, normally you'd realize your mistake and adapt, but you seem to persist in purposefully misunderstanding what it means when people talk about 'room temperature fusion'. Let me spell it out once more and then as far as I'm concerned we're done here. Room temperatu…
I have used the term Low Energy Nuclear Reactions (low relative to High Energy Nuclear Reactions in thermonuclear fusion). LENR allows for the creation of a cold fusion reactor, that can be started at room temperature and operated at low temperature, unlike thermonuclear fusion reactor. Please, see the difference between «nuclear reactions» and a «nuclear reactor».
> You really should read that sentence again. Cancel out the double negative and see if it makes sense to you.
Not a native speaker. It makes perfect sense in my native language. :-/
> This is complete nonsense.
I mean that delay or absence of medical treatment caused lot of premature deaths in these 30 years. Progress saves lives. Delaying of progress reverses the process.
> Science budgets are limited and tend to be directed to areas that are suspected to be fruitful. This makes it hard to get funding for what is - charitably - called crank science, which includes cold fusion.
As you see, private capital is not afraid about loss of scientific reputation. IMHO, it will easier to get funding for LENR reactors when they break the ice. I was unable to find a funding for similar idea before the war.
> If you are a strong believer in the concept you should fund it yourself rather than to put the burden of your beliefs on others.
I will try that after the war. However, I may pursuit a different goal - a bluster (photon streams with watts of energy per single photon), to kick Russian drones out from the sky.

Except history shows us that in 100% of the cases that working people seize the production and allocate the gains they do a unbelievable bad job. Socialism is the single most failed idea in human history, yet we refuse to properly teach that in our education system. I suspect in the future it will be view a bit like refusing to teach other scientific subjects, like evolution. In reality a mob of people end up produci…

For the record I believe I agree with you. However I view it as governments are the failure point in the issues you list, not markets. They have outright failed to address the negative externalities as they have been captured by private interests. In my opinion the entire financial system is captured and the regulations they tend to introduce are simply to allow the corrupt private entities further control. One neat…
Yes, the police are to blame for the rash of murders and arson is clearly the fire department's fault. It takes two to perform regulatory capture -- unless one of them can buy votes from lawmakers. And guess what the "market" found was most efficient?

Agreed. Stock markets are very similar to prediction markets. They are priced based on future projections, technical feasibility and probability of achieving certain milestone, ability to reach market first, internal and external factors, etc. I don't see much difference between a prediction market and a stock market. Theoretically, we could allow both of them and treat them similar. But one major risk I see is that…
"attempt to have the process replicated and buy options on the outcome once they confirm their findings in" This is called insider trading in stock markets and illegal. So your analogy breaks.

Refusing to view economic systems scientifically and quantifying objectively is a seriously big problem. Gotta stop the fairy tales.
So you will always end up with fiction dressed up in a scientific coat. It looks and talks like science but it really isn't. There are no testable hypothesis, there is a ton of politics and there will never be consensus.
