Comment Re:You will pay (Score 2) 82

How many concrete, proven cases of Chinese espionage via telecom hardware have been detected? Are the Chinese so skilled AND self-confident that they would deploy spyware in thousands of units to be deployed in adversary countries, who have full and unrestricted access to the actual hardware?

Because this looks a lot like a case of protectionism by fear-mongering. Leaving aside the whole PRISM thing.

No tipping means Soviet-style restaurants where the wait "staff" don't give a shit about you and tell you to go f yourself.

Never been to Europe? No tipping means waiters have a modicum of dignity and do not come along every 5 minutes asking "everything OK?!?" with a smile so fake it could be plastic.

And yes, sometimes we do tip, when there is extraordinary service involved, not when they did just what they were supposed to.

Comment Re:The price of cars is still shooting way up (Score 1) 173

Just like for ICE cars you will need to replace the engine and or the transmission at some point.

I find that unlikely, since EVs have neither of those things. EVs have electric motors (far cheaper and more reliable than high-temperature ICEs with thousands of moving parts) and there is neither gearing nor transmission required (the motor is installed directly on the shaft).

I live in Norway, where EVs were phased in much earlier, and EVs are well-known to be cheaper to maintain and way more reliable than ICEs.

Comment Re:Battery Wars. (Score 1) 173

[...] assuming we'll never find another type of material to make a future battery out of.

That's because there isn't. Lithium is irreplaceable for high-density battery storage because it has an extreme electrode potential and extremely low weight. I mean literally extreme since there is no material with higher (well, lower since it has a minus sign) electrode potential for a plain ionisation, and there is no lighter solid material.

You can play with all the other metals and components in batteries like nickel, aluminium, molybdenum, iron, phosphates, but lithium is the one carrying the charge and you can't replace it. If you heard of sodium batteries, those are only for stationary storage as sodium is a lot heavier than lithium.

Then you can think outside the box and go for hydrogen for fuel cells, which is lighter and does not need to be mixed with other metals for storage, but that's another technology entirely.

Comment Re:Do we though? (Score 4, Informative) 257

Did you forget to amortize $30b across 80+ years of operation?

Did you forget to account for capital costs? With a reasonable, non-commercial 4% interest rate, the present value of annuity factor converges to 25 years for an infinitely long depreciation horizon. (It's 23.9 years for 80 years of horizon). So it does not really matter that much whether the plant is going to last 40, 60 or 80 years to calculate the LCOE.

This is because you need to pay interest for those loans you took to build the plant to begin with. No one is going to give you 30 billion dollars interest-free, except for the government, but then we are in subsidised territory and taxpayers will be paying for that.

Comment What about work profiles? (Score 1) 65

My employer (in Europe) provides company phones for private use (nice perk), but also requires us to use a work profile (at least on Android) for work apps.

It is a bit clunky (e.g. I cannot copy and paste data between apps in separate profiles, but that's the point) but it works fine for us. Is there an inherent weakness to this approach that makes US employers rather give out an extra phone?

Comment Going against the principle of economies of scale (Score 3, Interesting) 345

So, the idea with SMR is to make many small reactors. The problem with current big ones is that they are too expensive, and making something smaller is not the way you usually go to reduce prices; but the argument is that building many identical SMRs will eventually bring the unit price down, with the point of contention being whether this can offset the loss of economies of scale.

However there is not just the reactor that is being scaled down: there are a lot of other things that benefitted from large scale.

  • Turbines: a usual large plant is in the GW scale and certainly don't have 1000/20=50 single turbines. Turbines need to be scaled down, which will reduce efficiency, and have pretty much the same requirements in term of maintenance (i.e. people working on site).
  • Personnel: do we even have the people to run hundreds of small nuclear power stations? I don't think you can just take any unemployed minimum-wage prospective burger-flipper and put them in charge of a nuclear plant. You need to have engineers with the right education: where are you going to find these? And even if they are there, there will be a lot more per MW than in a normal plant.
  • What about waste? The "solution" in traditional plants is "just leave it there until it's our grandchildren's problem", as all , but these small units do not have their own storage pools. Who and how is going to take care of the waste?
  • Containment building: have they decided these are optional now? Shit happens and without a containment building there is a much higher chance it will turn out serious. 50 Small containment buildings will cost more than a single big one.

I find it a dubious proposition that SMRs can be per-MW cheaper than traditional reactors, and I still have not seen a credible source (i.e. not a company brochure) claiming SMRs are any game changer.

Browsing in Google Scholar, I found papers are quite tepid, from "[modularized] SMRs [...] could possibly compete with large reactor baseline total construction costs" (Lloyd et al.) and "cost effectiveness of SMR [...] is in line and of the same order with LR’s" Boarin & Ricotti. This is not sufficient: nuclear power must come down with a factor of at least 4 before it's even competitive with renewables.

I appreciate any link to more recent or comprehensive TCO analyses of SMRs.

Comment Re:Motivation (Score 1) 352

Germany was pressuring Russia contractually to deliver gas (in Nordstream1). Each day the gas wasn't delivered, Russia had to pay a fine

How much was that fine that it trumped having a major bargaining chip to get Germany to back off from the war? Was the fine applied even if Russia claimed they were having "technical problems"?

And why in the world would they then destroy the pipeline at the border of Denmark and Sweden, instead of staging a false-flag "Ukrainian terror attack" at the terminal in Russia, which would have been a lot cheaper, safer, and allowed them to say they had finished repairs at the most convenient moment?

The non-competes will be replaced with far more consequential NDAs.

This is the situation we have in Europe and it's perfectly reasonable. Workers can pursue their careers, whereas companies are covered in case of industrial espionage.

Of course you are not supposed to talk about confidential information you learned through your previous job. If a company would not hire you unless you spy on your previous employer, you should not consider that company to begin with.

And let's not fool ourselves here, non-competitive clauses are there to keep wages low, not for information security.

Offshore wind turbines near Japan would need to be built to withstand earthquake and tsunami events

No they wouldn't. First, tsunamis far out at sea are long fast waves, and boats often pass them without even noticing them. The worst that can reasonably happen is some anchors coming loose. Second, even if the tsunami were enough to somehow topple the turbines, they are just pieces of metal like any other wreck in the sea - no possibility of further pollution beyond lubrication oil in the gears, and no crew that would need rescue.

Happy to oblige. You are looking only at the exports, but if you had looked at the makeup of the GDP you would have seen that more than half of the GDP is in the service sector, and only one third in industry (of which oil & gas is a large part). See also CIA's take on Norway's economical makeup.
