The only discipline in which SMES are an interesting option is high-power pulse sources. For storage of power plant production they are not interesting, as their energy density is order of magnitude lower than those of batteries. They are t

Do you realize all those are wishes, not plausible technology right now? Fusion power has more problems than just magnets needed to be kept cold. MRI machines are a niche thing, sure they could get cheaper but why should average Joe care? C

... with this method. My point is, even if we have room temp room pressure superconductors, this isn't as revolutionary by itself. The price is key and ordinary copper is likely to win in most places except where price does not matter,

I think you are right for tokamaks, room temp superconductor would change the design somewhat.

Room temperature superconductivity itself is not revolutionary for anything except academic papers. Lossless power lines and frictionless trains are a gimmick as those losses are small part of their operating cost. Resistance of copper cabl

But if people switch to those better CPUs, they will make the compilation even more complex... we just can't win the battle with bloated software.

Good question. Most people don't really need it, as systems work quite well for long enough time without it and no visible corruption happens. But if you are tech enthusiast who knows a thing or two about errors then you want it, bec

New workstation Xeons (Comet Lake), e.g. Xeon W-1250, W-1270, W-1290 are hard to find online but can be seen, in few places, for 350,500,800 euro. Motherboards for these Xeons (socket LGA1200) seem to be a somewhat pricier at 300 euro, but

Interesting! Do you think this BIOS or ECC works also on X370 Crosshair VI Hero? Hard to find info on this...

Do you know for which motherboards this is true? I think ASRock Rack X470D4U should be fine, as they market it as server board. https://www.servethehome.com/asrock-rack-x470d4u-review-amd-...

Of course, current computers are nowhere near capable to try out substantial portion of all 256 bit keys. It requires massive amount of energy and time to perform single bit operation, much larger than kT for room temperature T (several ord

That does not address it. It is true that heat has to be removed to maintain the lower temperature. But the rate at which this has to be done depends on heat generation and quality of isolation. If temperature inside is 1e-100 K, energy cos

Any source for such a wild claim? Interest rates are so low because people controlling the FED decided the rates to be low. They did so, as the story goes, to stimulate the economy growth, to make banks more likely to lend and companies mor

Indeed. With the recent course of US gov./FED decisions, debt seems pretty much already uncontrollable, it just keeps soaring and current powers at helm won't touch that problem with a ten foot pole. However, it seems to me that a

by effie 6y ago
Wealthy people have other people who manage their money. Only part of that money is in U.S. dollars/bonds at any given time, because it is less risky to have money in various different assets such as land, buildings, stocks.

You don't know what nobody thinks, because there may be a person that thinks just that. This is an active area of research. Anything quicker than O(nlog n) but slower than O(n) is still possible.

Isn't this a bit too much historical/wishful thinking perspective? I don't think people in Europe see UK as some kind of helper agent in maintaining balance of power/order in continental and northern Europe. UK is simply
