Yup, love the adrenaline rush, the simple "get up with this heavy shit on you" on it.

After running for a decade without any spectacular performance to speak of and constant weight issues, one year of powerlifting 2x a week - not only is every single health metric better with less running, possibly the best they've ever been, at a point where they should be declining; my running is hitting PBs as well.

The downside, I'm a bore about it.

Batteries cost > $100 / kWh, the industry still considers that a target to brag about: https://about.bnef.com/insights/clean-transport/lithium-ion-...

This is WHOLESALE BOM price, which is about as useful as the price of uranium.

That is horrifically expensive.

Levelised Cost of Energy is the highest, in the entire developed world, in the UK, which has enough wind and solar installed to entirely meet needs today.

It is NOT cheap, it is cheap for sellers, because they account on the basis of a MWh being equally useful all the time. It isn't. There are TWh-scale shortfalls in winter because, and a medieval peasant understood this, a shortage of ambient energy is what winter is, and it's worth paying energy penny you have to avoid its worst effects.

Business is not better. I've worked in the chemicals industry, and conferences in Europe have been like a wake for the last decade. I've overseen large orders go to China because, I could not give a shit how much it cost, the European green alternative - for delivery within Europe - could not guarantee timeframes, due to reliance on renewables. The Chinese shipped product could. That is your "cheap".

You can buy uranium from Russia, Kazakhstan, Mali, Canada, US, Australia, or the sea if you really want to, all of those have large reserves, and store multiple years' worth more or less by accident, modern industrial processes actually struggle to make sense at the low volumes nuclear requires. Bringing that up as a problem is just not honest.

They're absolutely dual use, which is why the greens have always been against them.

But that's like trying to prevent cow rearing by outlawing mince. You don't rear a cow for mince, you rear it for steak. The customer will pay for steak pretty much whatever.

My country just had ~180 GWh of lost load from wind, in winter. That's not even a 1-in-5 event, that's a multiple-times-per-year event, and it's billions in cost to the economy. Industry is dead, I've personally seen steel orders go to China because even if renewables were free we could't handle delivery estimates of "lol idk", and nor can anyone else. I just can't comprehend the levels of denial around this, as if my and literally everyone with industrial experience is irrelevant. Data centres want SMRs and that's the easiest, most trivial task to time-shift around I can imagine. Electricity that is not reliable is not the same product, it is not even a comparable product, in no other field would it be treated as such, and if you can't provide an actual monetary estimate for turning it into a reliable product, not just "iT's gEtTiNg cHeApEr BRO", you should not be in this conversation.

Regulations are paper. Who enforces the behaviour, of whether to take off or not, on a windy night in central Italy?

Of course the pilots are the backstop, and the unions are theirs, so they can make necessary calls the money doesn't like.

They are doing seasonal storage - i.e. on a timescale of a year! So no, they are not doing 5000 f*king cycles!

This is systematic fraud by the renewables industry and should be called out.

More efficient, but much more expensive. I'm sick of people handwaving $100 per kWh. That is two orders of magnitude off where it needs to be to do anything more than virtue signal.

Meanwhile multiple grids are now paying renewable to curtail, because guess what, the variability is correlated (it's the exact same damn mathematics we used to fuck up the entire global economy in 2008, which is why I'm so surprised people are handwaving that too, but whatever). If you want to minimise cost without relying on gas to save you on dark still days, you want a cheap use for the surplus, round-trip be damned.

I've received the same PIN from an entirely different gym chain, albeit one using the same door system.

As you say, a massive red flag indicating it's not using a lot of sources of entropy.

I'll name and shame - Fruit of the Loom.

They may never have been amazing, but that's the point - they were a representative, middle-of-road brand and you could just assume their clothes would last. I've got a >10 year old shirt that's still fine and a new one that's holed after a single wash. It's not a QA fail, the loss of quality is very clearly deliberate.

Aspiration for 20 GW of power by 2040, or in 15 years time.

In the period 1980-1990, I repeat in a 50% shorter period commencing forty years ago, France installed 34 GW of nuclear.

All I want is for someone advocating renewables over nuclear to give me a single example of a buildout of available-in-winter power exceeding that target with the forty years of investment available.

Or to agree that we have, fundamentally and quite deliberately, become worse at generating carbon-free energy.

If there's a single watt demanded by the grid and NOT supplied by gas, or coal or nuclear, because there sure as shit aren't batteries within three orders of magnitude of competitive at TWh scale, the entire grid fucking stalls and dies. At best guess, we can restart it, once.

Your renewable energy is worth 0 if it can't meet that need. No other power supply anywhere works on the principle of "yay maybe!". It's not a fucking game, it's our capacity to heat, to operate industrial processes that are equally worthless if interrupted. I've been involved in ordering steel. The UK-spec was uncompetitive if free, because of the unpredictability in delivery, directly downstream from the unpredictability in power. THERE IS A WAR ON.

It certainly leads to less sex. Seems a lot of vaguely-defined experts (economists/demographers/??) are very concerned we're not having enough, so more impulse-regulating drugs seem relevant.

Then again, maybe everyone being a 10 would level that out a bit?

> What do you mean by "metals don't actually withstand temperature"? As in the raw metal would melt were it not for the cooling vanes?

They creep. Have you seen, for instance, Blu-tac or glue fail? It doesn't go at once, but slowly, over a period of time. At high temperatures most metals (others on this thread have mentioned single-crystal blades) behave a bit like that.

Although steel is also weaker at temperatures far below its melting point, yes. A simple observation of a blacksmith at work should tell you that. And a think some new jets may be running hotter than Tm for steel now?

> The lower power setting on shutdown does what? Spin it at a low RPM so it doesn't decrease in temp too quickly?

Yup, or more relevantly evenly, although those tend to be related. Given almost all materials expand as they get hotter and contract as they cool, different cooling rates between parts -> different contraction rates -> different relative shape -> Very Bad in precision machinery.

And that's why Georgism exists! You can't offshore a plot of land.

If you've really managed to generate trillions in profit without using any, including indirectly (mining, showrooms, etc), fair enough. If your economic model is quite literally rent seeking, you can fuck off and give all those proceeds to whatever government ensures that land is not overrun by whatever raiders are historically a problem in your area. If you work for a living, you should be able to spend your earnings on a fancy apartment if you wish, and if a landlord wishes to make one instead of just sitting on land, they keep the profits from that too.
