nordsieck commented on Standard Thermal: Energy Storage 500x Cheaper Than Batteries   austinvernon.site/blog/st... · Posted by u/pfdietz

But chemical batteries cost a lot more and don't have lifespans of hundreds or thousands of years in seasonal storage scenarios.

And when electricity is in essence too cheap like with solar and wind it can be, losing half in efficiency actually doesn't matter too much.

Practically speaking, you're probably not going to get 1000s of years out of any storage method. There's just too much stuff that breaks down.

Heck - a lot of historic dams are in the low hundreds of years old and are experiencing serious problems.

IMO, the shorter lifespan of batteries isn't that big of a downside as long as the "bad" batteries can be mined for raw materials eventually.

Euch. That lefty-handed-curl is a solution proposed by the right handed world. The correct way to write as a left handed person is to turn the page ninety degrees.

That is such a genius solution!

What suggests that people are becoming less capable? More importantly, what suggests that people are becoming less capable in an irreversible way? If people are less capable, but it is reversible, then wealth can fix it. As you said, you can use wealth to get other people to become more capable.

From the root level comment in this thread:

> Student test scores have worsened more than in other Scandinavian countries, and critics of the government say there are too many boondoggle tunnels and bridges to nowhere.

> More importantly, what suggests that people are becoming less capable in an irreversible way? If people are less capable, but it is reversible, then wealth can fix it.

I don't think anyone is suggesting that this trend is irreversible.

But big trends like this can be difficult to turn around - if it were easy, the trend wouldn't have happened in the first place (or, at least, it wouldn't have been detectable).

> If people are less capable, but it is reversible, then wealth can fix it. As you said, you can use wealth to get other people to become more capable.

You can't just say "wealth will do x". That's really a semantic shortcut for saying "people will do x". But presumably people are already trying to improve the countries test scores. And people are already trying (at least to a certain extent) to spend government funds wisely. I'm not really sure how wealth will change what's currently occurring.

What's the problem? Only poor people care about test scores as they imagine high test scores is how one can pull themselves out of being poor. When you are rich you can also do pointless things just for the fun of it like build bridges to nowhere. None of these are problems unless you try and look at it through a poor man's lens.

Poorer health might be concerning, but is likely the result of the population growing older. More children would help make the numbers look better, I suppose, but, statistically, only poor people like having children.

That may be a reasonable take at the level of an individual. But it's nonsense at the level of a country.

Wealth is the ability to get other people to do things. But if everyone is becoming less capable, then that's not a problem that wealth can fix.

Outsourcing may be a temporary solution to his problem, but I don't see it working well long term.

It is not so much that used diamonds are worth less (although they might decline in value without provenance to prove they are natural or if they are chipped) but the huge markup on retail jewellery. It's easy for any member of the public to buy and sell gold at close to market price, it's much harder with diamonds.

Precisely.

And on top of that some jewelry stores are worried that customers would consider a below wholesale offer to be insulting, so they often refuse to buy piece back at all.

> They are looking at lightweight EVs at lower speeds. But Americans drive heavier EVs at highway speeds. The rotors & pads are huge.

Perhaps other EV drivers can chime in but, if anything, I think I use my friction brakes less at highway speeds where, in general, you're not really supposed to do a lot of braking. I'd say, overall and regardless of speed, my friction brakes are really used only to bring the car to a complete stop or for emergency braking to avoid a potential accident.

Some people are very responsible with money - they have an emergency fund, contribute to their retirement fund, and don't carry a credit card balance.

Other people (who have a choice) spend to 0 every month, don't save, and have maxed out credit cards.

In the same way, some people drive very safely; they keep a responsible distance between them and the driver in front of them, and don't tend to speed much. I think this style of driving would naturally lead to what you say - less use of friction breaks in general, and especially at highway speeds.

And other people are constantly speeding, and tailgate the person in front of them when their path is blocked. For the people who drive this way, the greater acceleration of EVs just lets them drive that much more recklessly. Which ends up necessitating even more usage of friction brakes.

From what I've heard there's a countervailing effect for EVs, though - they end up generating more particulate pollution from tire wear because of greater vehicle weight and greater torque.

The number that I've seen bandied about is ~20% greater tire wear.

> "So if we burn more of our energy every day on physical activity, on exercise, after a while our bodies will adjust and spend less energy on the other tasks that we sort of don't notice going on in the background," Pontzer says.

I also think this is true related to food. Your body adjusts its metabolism based on the amount of food you eat as long as it's not chronic. That's why you can have competitive eaters that can eat a weeks worth of food and not be overweight. Spikiness and variability are probably good for you. Its funny that the Bryan Johnson types who closely control every calorie in their body have such a bad reaction to any variability. I don't know if its him, but I heard someone not be able to sleep and their levels got all messed up from one sweet. And their conclusion was sweets are so bad for you, rather than you're building your body to be too fragile to shocks.

The interesting thing is when this breaks down. Obviously if you eat a weeks worth of food every day for a sustained period of time, you will start to gain weight. Or if you run 12 miles every day, you will be in such a deficit that it won't be possible to lower your metabolism enough. Outside of the extremes, I think it's a cliff, where you have to have some kind of shock for some period of time for your body to react.

Objectively, I don't think this is accurate.

Most people who are overweight got that way slowly.

Dr Mike[1]'s theory is that modern processed food is to blame - not because it's unhealthy, but because it's too tasty. Companies that make food are in an evolutionary arms race with other companies to get consumers to choose their products. And one of the best ways to do that is to make the food as tasty as possible.

Another things many companies probably try to optimize their food for is low satiety[2]. That way consumers consume, and therefore buy, more of their products.

It comes up from time to time if you watch Uber driver videos. There's a reason why many drivers have a camera that records the interior of the car: alcohol + entitlement can manifest in many ways.

Most commonly, passengers cancel the ride and expect to be driven to their destination anyways. But worse stuff happens from time to time.

There are lots of small operators, so I doubt that there's some industry wide list.

But there are only a few large operators. I'd be shocked if some of them didn't share info.
