Comment "Smaller than a hair" - no (Score 1) 15

If you read the article carefully, they are talking about lenses THINNER than a hair. I see several of the posts here thinking the width/radius of the lenses is this small, a reasonable mistake given the way this was written. Having a radius that small would severely reduce their light gathering ability, requiring very bright light or very dim images or very long exposure times.

I dunno. China is a "market socialist" system -- which is a contradiction in terms. If China is socialist, then for practical purposes Norway and Sweden have to be even *more* socialist because they have a comprehensive public welfare system which China lacks. And those Nordic countries are rated quite high on global measures of political and personal freedom, and very low on corruption. In general they outperform the US on most of those measures, although the US is better on measures of business deregulation.

"It uses less electricity than a modern frig"

So that seemed incredible; but after doing some research it is plausible (with caveats). I have a few questions:

1) What 'modern' fridge are you using for comparison? There is a substantial difference between 1982, 2002 and 2022.
2) What are the volumes of the two fridges being compared?

The average 1940s fridge looks to be only 6-8 cu ft; while the average 2000s fridge is 20+ cu ft. Even if it slightly beats the modern fridge on total electricity, it's probably only cooling 1/3 to 1/4 the volume

For example in the 1940s you might be around 400kWh; but if its 7cu ft, its only getting 57kWh/cu ft/year; and comparing it to a 550kWh fridge from 2002 cooling 21 cu ft for 26kWh/cu ft/year. (And that's a 20 year old not particularly efficient "modern" fridge... you could get that down to 300kWh annually on a new fridge if you buy specifically for efficiency)

Sure the 1940s fridge might beat that not particularly modern or efficient "modern fridge" on total use but it's still not really a win unless you only need 7 cu ft. And if all you need is 7 cu fit, in 2025 you can get 8 cu ft for 167kWh year. (60% less electricity)

It makes no sense to claim Chinese courts have a lot of power, although it may seem that way â" itâ(TM)s supposed to seem that way. One of the foundational principles of Chinese jurisprudence is party supremacy. Every judge is supervised by a PLC â" party legal committee â" which oversees budgets, discipline and assignments in the judiciary. They consult with the judges in sensitive trials to ensure a politically acceptable outcome.

So it would be more accurate to characterize the courts as an instrument of party power rather than an independent power center.

From time to time Chinese court decisions become politically inconvenient, either through the supervisors in the PLC missing something or through changing circumstances. In those cases there is no formal process for the party to make the courts revisit the decision. Instead the normal procedure is for the inconvenient decision to quietly disappear from the legal databases, as if it never happened. When there is party supremacy, the party can simply rewrite judicial history to its current needs.

An independent judiciary seems like such a minor point; and frankly it is often an impediment to common sense. But without an independent judiciary you canâ(TM)t have rule of law, just rule by law.

I'll take that bet. If it was leaking refrigerant, it wouldn't be working.

Fair comment, but the point stands that it's in there and sooner or later it will.

And how much energy would it take to manufacture 8 replacement refrigerators (assuming 1 per decade)?

That's such an arbitrary calculation. The big turning point was in the 70s energy crisis when energy star became a thing. And there is a huge efficiency jump from 1970 to 1980; sure 2020s appliances are significantly more efficient than 1980s appliances but is a logarithmic improvement curve and there's no justification to buy one every 10 years.

Hereâ(TM)s the problem with that scenario: court rulings donâ(TM)t mean much in a state ruled by one party. China has plenty of progressive looking laws that donâ(TM)t get enforced if it is inconvenient to the party. There are emission standards for trucks and cars that should help with their pollution problems, but there are no enforcement mechanisms and officials have no interest in creating any if it would interfere with their economic targets or their private interests.

China is a country of strict rules and lax enforcement, which suits authoritarian rulers very well. It means laws are flouted routinely by virtually everyone, which gives the party leverage. Displease the party, and they have plenty of material to punish you, under color of enforcing laws. It sounds so benign, at least theyâ(TM)re enforcing the law part of the time, right? Wrong. Laws selectively enforced donâ(TM)t serve any public purpose; theyâ(TM)re just instruments of personal power.

Americans often donâ(TM)t seem to understand the difference between rule of law and rule *by* law. Itâ(TM)s ironic because the American Revolution and constitution were historically important in establishing the practicality of rule of law, in which political leaders were not only expected to obey the laws themselves, but had a duty to enforce the law impartially regardless of their personal opinions or interests.

Rule *by* law isnâ(TM)t a Chinese innovation, it was the operating principle for every government before 1789. A government that rules *by* law is only as good as the men wielding power, and since power corrupts, itâ(TM)s never very good for long.

I bet it uses 4-5x the electricity of a modern one and is slowly leaking Freon too. Nice flex!

You probably could pay for a new basic fridge in a couple years with what you are wasting in electricity to run that old one.

Get a new one without an ice maker and just use ice trays and it'll be rock solid too. (The vast majority of the reliability issues across ALL brands are in the ice makers.)

If I watch you drown and do nothing, even though I'm a capable swimmer standing next to a bunch of flotation devices, and all of this is caught on camera, your family could probably sue me for causing your death even though I'm not a lifeguard and do not own the pool.

The equivalent here is suing the camera manufacturer, as if the camera should have done something when it saw the drowning.

The BLS jobs data is from the CES (Current Employment Survey). This is a survey of firms, not of the public. That's what Trump was complaining about. Whatever is wrong with that survey seems to be very new -- it used to be revisions were fairly evenly distributed, but since 2023 the revisions have been very biased downward. It seems unlikely this has anything to do with public survey fatigure.

The unemployment numbers come from a public survey (Current Population Survey), but those are different from the jobs numbers.

I think the real issue is warm parts of China selling to cold parts of India without including the features that aren't needed near the factory. We know lots about battery chemistry, but rural farmers have had more immediately relevant things to know about up to now and don't have a good source of information on this new thing the government is pushing, so they skip things that sound like luxuries and end up with something inappropriate for their purpose.
