Or maybe use excess power to electrolyze water for fuel cell use later?
Hydrogen storage presents a lot of challenges, because it tends to leak at normal temperatures found on Earth. So we either tolerate a lot of loss during storage, or we use lots of energy chilling it to a temperature where it won’t easily escape.
- Comment on Is there a point we can track down when we stopped caring about doctors, nurses, teacher, etc? And thought it was a great idea to pay atheletes millions and screw everyone else? 2 days ago:
There are about 500 NBA roster spots. Total basketball related income across the league is $10.25 billion, and the CBA requires that player income make up half of that. So there’s $5.13 billion to split between 500 players, an average/mean of $10.25 million per full time player (some players get called up or put on reserve when injuries or something like that happen).
There are about 3.8 million public school teachers in K-12. If you took literally every dollar paid to NBA players and gave it to public school teachers, that’d be about $1350 per teacher.
There are other sports, of course, but we’re also talking about nurses and doctors and EMTs and public librarians and other important underpaid jobs. Taking all money from sports isn’t going to make much of a dent in those other jobs’ pay.

Ridiculous pay for star athletes and celebrities is at least fair
Put another way, we as a society actually do spend wayyy more money on doctors, nurses, and teachers. It’s just that there are many millions of people who have to split that pot of money, whereas for pro athletes there are only a few dozen or a few hundred to split that comparably smaller pot of money with.
I might have the same favorite NBA player as literally millions of people in this country. I for sure don’t have the same favorite doctor or favorite teacher, though.
So if a genie showed up and said “give $1 to your favorite celebrity and give $100 to your favorite teacher,” we as a society would give way more money to the teachers, but each individual teacher would receive less than each individual celebrity who gets paid under this system.
- Comment on U.S. consumers are so fucked up, that they put more than $1 billion on buy-now, pay later services during Cyber Monday 3 weeks ago:
Yeah but it’s pretty nice to be able to take advantage of a promo deal as long as it’s not a sticky long term relationship. Some people in this thread are talking about a reward system of 20% cash back on what you put on BNPL, and 0% interest, as some kind of Paypal promo going on during Black Friday.
If you take the deal as a one time thing, it’s a great deal. They hope that you might get used to using the service next time it’s not such a great deal, but if they don’t have a way to lock you in, then just take the money and run.
See, for example, the glorious year of MoviePass setting its own money on fire. People got great deals on movie tickets, and then the company went bankrupt and didn’t keep their customers.
- Comment on happy buy nothing day to those who celebrate 4 weeks ago:
The base price of TVs have gotten so cheap that in terms of absolute savings, even a true 50% discount wouldn’t seem like a big deal.
30 years ago, when a big screen TV might cost the same as 3 months rent in a 3 bedroom apartment, getting 50% off was like getting 1.5 months rent. Now, when a big TV costs less than a quarter of a month’s rent for a studio apartment, getting 50% off a TV is like getting 3 days rent.
Modern life is expensive because of housing, not because of stuff. Giving us better prices on stuff doesn’t even help make this life more affordable.
- Comment on ICE tries to kidnap random food delivery driver off the street. He jukes them on a foldable bike. 2 months ago:
He was circling on the bike taunting them, saying stuff like “I’m not an American citizen,” and the ICE dudes just tolerated it until the bike rider dropped his phone, and detected weakness and pounced, before the guy snatched up his phone and managed to ride away.
Tragicomedy is the best description.
- Comment on Shamelessly stolen from Reddit 4 months ago:
Why are you forgiving student loans?
That’s the federal government’s administration of a federal government program, so no, that’s not the same at all.
Why do you tip servers in America?
That’s the basic deal. If a restaurant implements a no tipping policy, they’re allowed to do that. I don’t see how that’s the same or different from a restaurant implementing a “discount for veterans” or “no discounts for veterans” policy. It sounds like we’re in favor of a system where the restaurant chooses what they want to be about, whether it’s a tip-based system or not, or a discounts for vets place or not.
So in a sense, it sounds like you agree with me that we should let the restaurants choose. Neither choice is a “punishment” of anyone.
- Comment on Shamelessly stolen from Reddit 4 months ago:
But really you’re just punishing veterans with PTSD
Failing to give special treatment to someone is not punishing them. Especially when we’re talking about special treatment for an entire category of people, most of whom don’t have PTSD (estimates range from 6-27% of those deployed to a war zone, and not all veterans served in a war zone), many of whom are financially well off.
Maybe the VA and the federal government should do more for vets. Maybe the military itself should take care of the troops a bit better. But asking private businesses to prop up veterans at their own expense seems like a misguided approach.
- Comment on YSK that Gerrymandering allows politicians to choose their own voters. In many countries, it's illegal. Gerrymandering is common in the United States 4 months ago:
The American political system was designed for weak parties, and geographical representation above all, in a political climate where there were significant cultural differences between regions.
The last time we updated the core rules around districting (435 seats divided as closely to proportionally as possible among the states, with all states being guaranteed at least one seat, in single member districts) was in 1929, when we had a relatively weak federal government, very weak political parties, before the rise of broadcasting (much less national broadcasting, or national television, or cable TV networks, or universal phone service, or internet, or social media). We had 48 states. The population was about 120 million, and a substantial number of citizens didn’t actually speak English at home.
And so it was the vote for the person that was the norm. Plenty of people could and did “switch parties” to vote for the candidate they liked most. Parties couldn’t expel politicians they didn’t like, so most political issues weren’t actually staked out by party line.
But now, we have national parties where even local school governance issues look to the national parties for guidance. And now the parties are strong, where an elected representative is basically powerless to resist even their own party’s agenda. And a bunch of subjects that weren’t partisan have become partisan. All while affiliations with other categories have weakened: fewer ethnic or religious enclaves, less self identity with place of birth, more cultural homogenization between regions, etc.
So it makes sense to switch to a party-based system, with multi member districts and multiple parties. But that isn’t what we have now, and neither side wants to give up the resources and infrastructure they’ve set up to give themselves an advantage in the current system.
- Comment on When will we have reached enough productivity? 5 months ago:
Increasing productivity of workers is met with demand for more production-intensive products. It’s like how every time hardware improves, software becomes more complex to take advantage of that increased capability. It’s like Jevon’s Paradox, but applied to productivity of workers.
One prominent example: our farmers are more productive than ever. So we move up the value chain, and have farmers growing more luxury crops that aren’t actually necessary for sustenance. We overproduce grains and legumes, and then feed them to animals to raise meat. We were so productive with different types of produce that we decided to go on hard mode and create just-in-time supply chains for multiple cultivars so that supermarkets sell dozens of types of fresh apples, tomatoes, potatoes, onions, etc., and end up eating much more fresh produce of diverse varieties compared to our parents and grandparents, who may have relied more heavily on frozen or canned produce, with limited variety.

- Comment on YSK that apart from not having a car, the single greatest thing you can do for the climate is simply eating less red meat 5 months ago:
I fear that the likes of Trump in charge will only reverse any progress we’ve made in the West.
It may end much of the progress towards people voluntarily sacrificing for the environment, but I think certain technologies are already on a runaway self sustaining cycle:
- Heat pumps and electrification of residential heat is starting to make financial sense, even without subsidies and tax breaks.
- Electrification of cars makes transportation cheaper. In some countries, much, much cheaper.
- Solar power, during times of day that it is plentiful, is basically the cheapest energy source known to mankind. There is plenty of financial incentive to try to shift supply (through grid scale storage tech) and demand (time shifting things like heating/cooling and car charging) to meet this super cheap source of energy.
Trump can rant about carbon-free replacements for fossil fuels, but he can’t make them more expensive, especially not outside of the U.S.
- Comment on YSK that apart from not having a car, the single greatest thing you can do for the climate is simply eating less red meat 5 months ago:
That’s a good chart, and probably a better metric to use.
Still, you can see the same overall trends: the western world peaking around 2000, with India and China catching up. The question, then, becomes whether and how much the rest of the world can follow the West’s playbook:
- Switching from coal to natural gas for electricity generation (easy for North America, more difficult for Europe)
- Switching from fossil fuels entirely to carbon-free sources like nuclear, solar, wind, geothermal (depends heavily on geography and access to nuclear materials and engineering).
- Switching from fossil fuels to cleaner electrified drivetrains
- Improving energy efficiency in residential, commercial, industrial applications.
This is where the difference is made. Not in changing birth rates.

The big assumption is that the child you have will likely consume carbon-emitting goods and services at the same rate as whatever average they’re assuming.
Breaking down by country shows that people’s emissions vary widely by year and by country:
ourworldindata.org/…/co-emissions-per-capita
So if the UK spent most of the 20th century, and into the beginning of this century, emitting about 10 tonnes per person per year. Now it’s down to less than 5. Since your linked article was written in 2017 to the latest stats for 2023, the UK has dropped per capita emissions from 5.8 to 4.4, nearly a 25% reduction.
During that same 125 years, the US skyrocketed from about 7 tonnes to above 20, then back down to 14.
The European Union peaked in around 2001 at 10, and have since come down to 5.6.
Meanwhile, China’s population has peaked but their CO2 emissions show no signs of slowing down: ourworldindata.org/co2-emissions-metrics
So it takes quite a few leaps and assumptions to say that your own children will statically consume the global or national average at the moment of their birth. And another set of assumptions that a shrinking population will actually reduce consumption (I personally don’t buy it, I think that childless people in the West tend to consume more with their increased disposable income). And a shrinking population might end up emitting more per capita with some sources of fixed emissions amounts and a smaller population to spread that around for.
If the US and Canada dropped their emissions to EU levels we’d basically be on target for major reductions in global emissions. If we can cap China’s and India’s future emissions to current EU per capita levels that would go a long way towards averting future disaster, too.
It can be done, and it is being done, despite everything around us, and population size/growth is not directly relevant to the much more important issue of reducing overall emissions.
- Comment on YSK that apart from not having a car, the single greatest thing you can do for the climate is simply eating less red meat 5 months ago:
Those companies are creating the pollution to make the things we buy. They know how to reduce output when demand goes down (see March and April 2020 when COVID caused lots of canceled flights and oil drilling/refining to reduce to the bare minimum to keep the equipment maintained).
Yes, ExxonMobil and American Airlines pollute, but when I buy from them, they’re polluting on my behalf.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 5 months ago:
No, LCOE is an aggregated sum of all the cash flows, with the proper discount rates applied based on when that cash flow happens, complete with the cost of borrowing (that is, interest) and the changes in prices (that is, inflation). The rates charged to the ratepayers (approved by state PUCs) are going to go up over time, with inflation, but the effect of that on the overall economics will also be blunted by the time value of money and the interest paid on the up-front costs in the meantime.
When you have to pay up front for the construction of a power plant, you have to pay interest on those borrowed funds for the entire life cycle, so that steadily increasing prices over time is part of the overall cost modeling.
- Comment on 5 months ago:
apparently then it was around 20% to 25% as well
No, the unemployment rate was around 20-25% under the traditional definition. It’s currently 4.2% under that definition.
If you want to use this LISEP definition, fine, but recognize that it’s been above 30% for most of its existence, and has only been under 25% since COVID. Basically, if you go by the LISEP definition then you’re saying that the job market after COVID has been better than it has ever been before.
- Comment on 5 months ago:
When the definition of unemployed is changed to exclude the majority of working age people without jobs then it is no longer a helpful statistic.
U-3 has used the same definition of unemployed since 1940.
Whatever metric you want to use, you should look at that number and how it changes over time, to get a sense of trend lines. LISEP says the “true” unemployment rate is currently 24.3% in May 2025, which is basically the lowest it’s ever been.
Since the metric was created in 1994, the first time that it dipped below 25% was briefly in the late 2010’s, right before COVID, and then has been under 25% since September 2021.
Under this alternative metric of unemployment, the unemployment rate is currently one of the lowest in history.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 5 months ago:
My problem with nuclear is both the high cost and, somewhat counterintuitively, the very long life cycles to spread that high cost. The economics only make sense if the plant runs for 75 years, which represents an opportunity cost of displacing whatever might be available in 25 or 50 years.
A solar plant planned in 2025 might be online in 2027, and decommissioned in 2047, replaced with whatever technology/economics are available then. But a new nuclear reactor bakes in the costs for 80+ years, to be paid by ratepayers who haven’t been born yet.
So if in 2050 a 2030-constructed nuclear plant is still imposing costs of $66/MWh on ratepayers, to finance the interest and construction costs from 25 years earlier, will that be competitive with the state of solar/wind/batteries/hydrothermal at that time? Given the past trend lines, it seems economically foolish to lock in today’s prices for the next 80 years.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 5 months ago:
This paper lays out the cost projections that one could expect with the lessons learned from Vogtle Units 3 & 4, with the tax credits and government guarantees available as of 2024:
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 5 months ago:
Ok, current projections are still for the next two AP1000s at Vogtle to be something like $10 billion. That’s just not cost competitive with solar/wind. And it’s also not very realistic to assume that there won’t be cost overruns on the next one, either. Complex engineering projects tend to run over.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 5 months ago:
Also where did you see they did amortization of solar?
I’m just familiar with Lazard’s LCOE methodology. The linked paper talks about LCOE, so that’s just how that particular cost analysis works.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 5 months ago:
Vogtle added 2 AP1000 reactors for $35 billion. Future deployments might be cheaper, but there’s a long way to go before it can compete with pretty much any other type of power generation.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 5 months ago:
But the other misleading part is they looked at 20 years which is close to the life cycle for solar/batteries and not even half the life of nuclear
I think Lazard’s LCOE methodology looks at the entire life cycle of the power plant, specific to that power plant. So they amortize solar startup/decommissioning costs across the 20 year life cycle of solar, but when calculating LCOE for nuclear, they spread the costs across the 80 year life cycle of a nuclear plant.
Nuclear is just really, really expensive. Even if plants required no operating costs, the up front costs are so high that it represents a significant portion of the overall operating costs for any given year.
The Vogtle debacle in Georgia cost $35 billion to add 2 MW of capacity. They’re now projecting that over the entire 75 year lifespan the cost of the electricity will come out to be about $0.17 to $0.18 per kilowatt hour.
- Comment on Judge Rules Training AI on Authors' Books Is Legal But Pirating Them Is Not 5 months ago:
Archive.org was distributing the books themselves to users. Anthropic argued (and the authors suing them weren’t able to show otherwise) that their software prevents users from actually retrieving books out of the LLM, and that it only will produce snippets of text from copyrighted works. And producing snippets in the context of something else is fair use, like commentary or criticism.
- Comment on Judge Rules Training AI on Authors' Books Is Legal But Pirating Them Is Not 5 months ago:
just spitting the information back out, without paying the copyright source
The court made its ruling under the factual assumption that it isn’t possible for a user to retrieve copyrighted text from that LLM, and explained that if a copyright holder does develop evidence that it is possible to get entire significant chunks of their copyrighted text out of that LLM, then they’d be able to sue then under those facts and that evidence.
It relies heavily on the analogy to Google Books, which scans in entire copyrighted books to build the database, but where users of the service simply cannot retrieve more than a few snippets from any given book. That way, Google cannot be said to be redistributing entire books to its users without the publisher’s permission.
- Comment on Judge Rules Training AI on Authors' Books Is Legal But Pirating Them Is Not 5 months ago:
No. The court made its ruling with the explicit understanding that the software was configured not to recite more than a few snippets from any copyrighted work, and would never produce an entire copyrighted work (or even a significant portion of a copyrighted work) in its output.
And the judge specifically reserved that question, saying if the authors could develop evidence that it was possible for a user to retrieve significant copyrighted material out of the LLM, they’d have a different case and would be able to sue under those facts.
- Comment on Judge Rules Training AI on Authors' Books Is Legal But Pirating Them Is Not 5 months ago:
The law says this is ok now, right?
No.
The judge accepted the fact that Anthropic prevents users from obtaining the underlying copyrighted text through interaction with its LLM, and that there are safeguards in the software that prevent a user from being able to get an entire copyrighted work out of that LLM. It discusses the Google Books arrangement, where the books are scanned in the entirety, but where a user searching in Google Books can’t actually retrieve more than a few snippets from any given book.
Anthropic get to keep the copy of the entire book. It doesn’t get to transmit the contents of that book to someone else, even through the LLM service.
The judge also explicitly stated that if the authors can put together evidence that it is possible for a user to retrieve their entire copyrighted work out of the LLM, they’d have a different case and could sue over it at that time.
- Comment on Judge Rules Training AI on Authors' Books Is Legal But Pirating Them Is Not 5 months ago:
Does buying the book give you license to digitise it?
Does owning a digital copy of the book give you license to convert it into another format and copy it into a database?
Yes. That’s what the court ruled here. If you legally obtain a printed copy of a book you are free to digitize it or archive it for yourself. And you’re allowed to keep that digital copy, analyze and index it and search it, in your personal library.
Anthropic’s practice of buying physical books, removing the bindings, scanning the pages, and digitizing the content while destroying the physical book was found to be legal, so long as Anthropic didn’t distribute that library outside of its own company.
- Comment on Judge Rules Training AI on Authors' Books Is Legal But Pirating Them Is Not 5 months ago:
The court’s ruling explicitly depended on the fact that Anthropic does not allow users to retrieve significant chunks of copyrighted text. It used the entire copyrighted work to train the weights of the LLMs, but is configured not to actually copy those works out to the public user. The ruling says that if the copyright holders later develop evidence that it is possible to retrieve entire copyrighted works, or significant portions of a work, then they will have the right sue over those facts.
But the facts before the court were that Anthropic’s LLMs have safeguards against distributing copies of identifiable copyrighted works to its users.
