KW per cm2 would be fine. I know intuitively what is an inch, a pound, a KG and a cm, but I do not know what is normal atmospheric pressure (except I know as a trivia question that it's 15ish PSI). It's like a fish doesn't know what it is to be wet.
Pressure matters when it pushes on something, so you want to know what will be the force based on the size of the something...

The push for EVs (at least in Europe and Asia) is that governments are sick of oil being used as geopolitical leverage by the US.

Flash memory invented in 1984.
This is a great example of a technology with a slow innovation curve, but one that would eventually come to replace a lot of other things.
If you were smart, you would have known that (for example) tape based video cameras were going to be disrupted when flash memory hits enough density.
These things are tricky to think about because in many cases the growth curve is exponential, so something goes from "few kilobyte Nintendo cartridge" to "multi-terabyte SSD on a stick" in the matter of 4 decades.
These things are important to see and keep an eye on, because they are sitting there in plane sight, but most people don't pay attention - and they change how the future will look.

Oh, this is very interesting.
I was thinking about monkeypox today, how it happened right in the middle of the covid pandemic and it threw the pandemic machine off balance by introducing another virus which threatened one of The King's Protected Classes.
And it started with a bunch of monkeys escaping a truck that was overturned (kind of a buried news item)...
I have a feeling it might have been sort of an anti-covid team which was striking back against the covid team - because the timing and how it threw the media off balance BADLY.
Then of course what really ended covid was Russia invading Ukraine.

Unions can do that, yes. Particularly in Illinois where it's all just mafia.
But I think America's problems go deeper than this. The Americans who are willing and able to do real work and care about customer needs have been systematically shut out of the workforce for political reasons. And those who remain have been trained not to care about efficiency and customer needs, but instead about social causes.
In China, hard work and customer focus are specifically promoted by the central government. They have their own corruption problems, and over the next 100 years, the US is probably going to do better, but right at the moment they're ahead...

Finally watched the video. They're subtweeting BYD pretty hard, I don't think that's proven yet at all.
I think companies like Ford and Chrysler are not being serious about serving their customers, so BYD's sub-10k offerings might be trash and they might be quite decent for the money.
Also the notion that the only reason these are cheap is China govt subsidies is not really true. Dacia sells sub-10k vehicles in Europe and they're not "good", but they're are decent enough that taxi companies use them.
The idea that a car starts at 30k is an American phenomenon.

Yeah, this is a real problem, and I'm not sure there's any real incentive to stop it.
IMO it's not specifically the fault of EVs, but rather that as reliability improves, people stop caring about repairability. Even back in the 80s when they started cramming everything under the hood, timing chains that are ~impossible to service, etc.
You might imagine that delivery companies, taxi companies, cop fleets, etc will insist on buying cars they can service - but even for them, if the vehicle lasts 10 years without trouble, they might just not care.
Problem is, new car buyers are stupid, and they trade in every 5 years or so, so reliability after the first decade is not their problem. Maybe if the used market commands 20% of the car's initial cost, that matters, but if the car company can cut cost by 20% by making it impossible to maintain, it's a wash. And the company could also buy back used cars to support the market - even though they're junk.
For the car culture this is hell. You can put together an LS rig, and you can put together a rig on top of a commodity electric chassis, but in either case this is something you have to completely build yourself. Seems like there's just nothing comparable to Fox Body or Camaro ecosystem anymore...

Leaf batteries lid is glued on with some kind of sealant. There are a few ways to cut it so you can pull the lid off.

See point 5, in the early days that was widely expected to happen, but batteries actually exceeded expectations.
The age out period seems to be about a 10-20 years (before the battery life degradation starts to make the car annoying to drive).
You can just look at used EVs for sale and look for the remaining battery capacity (the computer reports this). 90% in a 10 year old car is not uncommon.
Anything you drive daily, you're going to spend more on fuel than on the car itself, so in the (say) 15 years of battery usable life, you've saved more than enough gas money to buy a new car.
And if you live in the north where they salt the roads, you are saving absolutely nothing because the rest of the car has the same lifespan.

2026-03-28 17:16:25 UTC

With oil getting expensive, and looking to only become more and more expensive, I've been doing a little bit of research on electric cars lately. Here are some of the things I've found:
1. Gasoline engines are about 30% efficient (diesels about 40%). Gasoline has 36 kWh/gallon of chemical energy, so a gasoline engine makes about 11 kWh/gallon.
2. If you pay 20 cents per kWh then that equals $2.20/gallon-equivalent (just multiply your price per kWh by 11 to get gasoline gallon equivalent price) - if you're paying more than that for gasoline, it's cheaper to drive electric.
3. Battery capacity is indeed quite small, a 100kWh battery used in Teslas is one of the biggest, and that's ONLY equivalent to about a 10 gallon tank. And most batteries are 30-60Kwh... That's why everyone speaks in terms of miles of range.
4. From range and capacity, you can deduce equivalent MPG. One Tesla Model S declares 240 miles of range for a 70 kWh battery, that divides to 3.43 miles per kWh, or 37.7 MPG.
5. Early on, there was a lot of fear that battery degradation would bound the lifetime of EVs to about 5 years. We all have experiences with laptops and phones from the 2000s and 2010s which the batteries degraded to the point that they would not even hold 1 minute worth of charge. The good news is this fear turned out to be unfounded. Improved battery chemistries and active cooling has more or less solved this problem, and degradation in EVs is slow and well understood.
6. Not all EVs are alike. As with ICE vehicles, some are quite decent, others are best avoided. With ICE vehicles, there are well known disasters such as Wet Belts, CVT Transmissions, or the Hyundai Theta II engine. With EVs, the problem is less about catastrophic failure and more about oddball designs where replacement parts are rare and expensive, or are simply too difficult to work on. EVs are somewhat unique in that some of them were made in extremely small production runs and in that case, there are few in junk yards and repair parts are in short supply.
7. Not all EVs are alike. Every modern car is locked down to some extent in order to make it more difficult to repair. With EVs as with ICE cars, some of the more popular platforms have been reverse engineered and have a decent aftermarket. So every car platform has two variables: How anti-repair it is made from the factory, and how well has it been reverse-engineered. Tesla is very repair-hostile, but has a large community that has figured a lot of things out. The Nissan Leaf is a fair bit less hostile, and also has a large community and even has aftermarket / Frankenstein battery packs that some people build.
8. Not all EVs are alike. Big dumb touchscreens, and doors that don't open without electricity so you can't get out in a crash are not obligatory. Be smart.
9. The best EVs seem to be the ones which started being made a long time ago (plenty of time to work out the bugs), and are made in large number, by stable car companies w/o financial problems. Chevrolet Bolt and Nissan Leaf seem to be fairly good - do your own research of course.
10. Electric motors are more or less bulletproof, so in an EV, the only part that you really need to worry about is the battery pack. Most EV battery packs are removable (WARNING: NOT ALL). They are very heavy so you need jacks to get them out, but once they're out they can be repaired on a workbench.
11. You can usually buy second-hand batteries out of a junk yard (check this before buying a car!). This is the most common way batteries are swapped. You can also (depending on the car) go into the battery pack and do repairs or cell replacement. This is quite dangerous as you're dealing with a uniquely deadly combination of high voltage, and insanely high available amperage - and there's no way to "cut power" because inside of the battery IS the power. So some shops will be happy to swap batteries but unwilling to open them, even if the only thing that failed is a small relay.
10. If you're looking at used EVs, you want to know State of Health (SOH) and voltage difference between cells. Different voltage between cells is a sign of failing cells. If this isn't available in the on-board computer, take it to a shop that does EVs and have them pull the numbers before buying.
11. EV owners often do not charge to 100% because filling all the way degrades the battery faster. There is a setting in the onboard computer to make the car stop charging at 90% or 80%. There is LOTS of advice online about this, reality depends on your battery chemistry. Most EVs are NMC (Nickel Manganese Cobalt) batteries, some newer ones are LFP (Lithium Iron Phosphate).
12. Battery fires are another problem that is more-or-less solved, UNLESS, you are in a serious accident that punctures the battery. NMC batteries are known to burn, LFP are much safer in that regard, new/experimental chemistries are being developed which will not burn at all but we're not there yet.
13. EVs do not wear out the same way as ICE vehicles (!!!!) In an ICE vehicle you look at the miles on the odometer to see how worn out it is. A 50 year old car with 20,000 miles is "brand new" as long as it lived its life in a garage. Batteries wear just from sitting, so calendar years on a battery matter, even if it was rarely ever driven in those years. On top of that, EVs from the earlier years had more teething issues, so newer models are often a better choice. In the case of the Leaf, pre-2016 models had a design flaw that cause excessive battery degradation, from 2016 through 2019 quality continuously improved, then after 2020 it became more variable with some QC issues popping up. This kind of "good years and bad years" thing is typical of all models, Do Your Research.
I think that's about everything... Let me know if there's anything you're curious about that I didn't mention.

Yeah, open question is how multi-cultural does it have to be to be really multiculturalism. Founding America is multi-cultural because it mixed various Europeans together... That had mixed results (civil war still not settled), but it wasn't horrifyingly bad.

Important point is we don't really know what a post-pax-americana world is going to look like. We don't know what it will be like when countries are no longer under secret pressure from CIA or whatever to act against their own interests...

Slaves are a curse, they always have been. The benefit the slave holders at the cost of everyone else.
The real problem for a nation-state though is brain drain. You generally want to take care of all of your citizens by redistributing wealth away from the most productive to those in need - if you don't do that then you have elders starving etc.
But if you do that, and I start a state which welcomes foreigners with means and offers them zero tax, I might draw away your most productive citizens. This already happens with places like Poland, which is fairly well administered, but still the smartest and most productive polacks move to the US to make more money...
Also happens on a different scale with places like Malta, Singapore, Switzerland and (formerly) Dubai drawing away high-net-worths from their countries of origin.
Another version of this is China, hiring DRAM engineers away from Korea by offering them 10x their salary at home. They did this to bootstrap a home grown memory business...

1st class is "sufficiently racially/culturally homogenous that they will fight for each other". Families, tribes, whatever is required. The point is that they need to be this close.
They should also be the only ones voting or holding public office, because they're the only ones whose lives are on the line based on decisions of the state.
2nd class (families) can air grievances through their father/husband/son, and 3rd class are immigrants will flee if the state does not treat them well enough.
You want to get rid of the 3rd class entirely, I think a lot of people do, but countries which do that will struggle to be economically competitive because knowledge work requires migration of domain expertise. Think like El Salvador inviting American bitcoiners to go live there and start businesses... That's what we're talking about here, because everything exists in service to the 1st class.

A Nation which is stable is at it's heart, made up of three classes of people:
First Class: The men who are sufficiently homogenous (ethnically and culturally) to be willing to fight to the death to defend one another.
Second Class: Their families, who they will fight to the death defending, but who cannot directly reciprocate.

Yes, that is correct. UK and Germany are bordering on failed state territory, France is a bit different.
The French are, culturally, master diplomats, and by that I mean they are really good at knowing what they want, and how to get it. I know this is cliche, but it has depth that you don't see at first glance.
The French are not really concerned with LOOKING like they won, the appearance of having won is a bargaining chip that they will happily trade away in exchange for more of the things they actually want.
WW2 is an over-discussed topic, and France decided not to fight significantly on either side, but what's less noted is that while England was forced to decolonize, France actually kept most of their colonies. To this day, you can land in random little islands around the world and find people speaking French and using the Euro. And that's not even to mention the CFA Franc, which is a shitcoin that France somehow invented and got half of Africa to use as their currency...
To the modern situation, while Europe has these roving violent criminals which are protected like as if they're an endangered species, France has the appearance, but mostly without the substance. Paris is undoubtedly dirty and ugly, but when these guys try doing rape, the police shoot them.
And the French tend to do this wherever they go. In Canada, they have their own little Israel and the whole Canadian tax system is setup around pumping money from the Canadian Anglos over to them. It didn't used to be that way, but they stirred up a whole raft of shit, and now it is...

That's not a functioning way to decide if a war is likely to expand or not. Every Single War in history was "supposed to be quick". WW1 was supposed to be quick.

Who is likely to be able to stop the war is the Russians or Chinese, who are most likely in contact with everyone in the region - including any significant factions - because they're providing intel and support.
But trying to get something out of either Russia or China will require concessions that suck worse than just going without. Back to the old meme...

The GCC states are fucked, but I'm not sure what outcome they would think they're buying.
The US didn't start the war, Israel did. And the US can't end the war unless they're willing to pressure Israel (lol).
As long as the US is an empire, they are unable to walk away from the petrodollar and therefore the GCC. But Israel wants Iran destroyed because it's the only serious competitor in the region, so if the US wants to wind down the war, Israel will just escalate it to drag the US into a land war.
The smartest thing the US could do is declare bankruptcy and leave without destroying Iran so then Iran is Israel's problem. But that's unlikely to happen either because too many powerful people in America believe that they have to destroy Iran and setup Israel as a world government in order to bring back Jesus Christ.

That's about $2 per barrel. IMO it can go to around $20-30 per barrel without breaking oil markets because what will happen is oil in the gulf will reduce in price to account for the toll.
Oil in Saudi Arabia is worth $0 if it can't be brought out. KSA can mine oil profitably at around $50, so anything between $50 and $100 is pure profit for them. Iran can appropriate as much of that profit as they want, as long as KSA is still making enough money to be worth pumping, they'll still pump...

But still, tanked hydrogen is just not that great a deal.
You burn about 50kWh to fill a 50 liter tank.
You get back about 20kWh and only 10kWh of that is actual electricity.
If that tank costs you 100€ (low end), well, you can store 10kWh in a battery for about 700€ (assuming 2000€ 32kWh battery).
Small savings, big energy loss, expensive up-front costs (fuel cell, compressor, pipes).

I don't think the loss in pipes is that big of a deal. You need H2 rated tank valves, but any tank that's not either being filled or being emptied can be shut off, and then the pipes are not normally holding any pressure.

Right, you store at about 150 PSI / 10 bar. Same as compressed air, so you can use a compressed air or propane tank if you fill the tank with the binding material.
The problem is, the binding material is not cheap, and you still have to pay for the tank, and high pressure tanks are just not that expensive.

> palladium can bind hydrogen pretty well tho
There's a number of things that bind H2 - including a lot that are not precious metals. I didn't drill into them much because they don't really outperform tanks from a price perspective.
For example https://www.alibaba.com/product-detail/Safest-and-Most-Efficient-Solid-Hydrogen_1601558386946.html HyReachX Titanium-Manganese alloy is selling at 24€ per KG and it can bind about 1.5% H2 by weight (15g / KG).
15g is 1 liter at 200 bar. So if you spend 1200€ you have enough alloy to store the equivalent of 50 liters at 200 bar. But a 200 bar 50 liter steel tank is 100-500€ (depending on who you ask).

2026-03-19 01:27:16 UTC

- reply

I made a mistake in computing storage in an H2 tank.
1Kwh of power makes about 15g of H2 (assume 50% efficiency).
At 200 bar (3000 PSI) it's about 15g/liter.
So in a 200 liter high pressure tank, it's about 200Kwh of input energy that is stored.
So we can say: Rule of thumb, at pressure, 1 liter = 1 kWh. In a balloon, 1 cubic meter = 6 kWh.
But there's another way to lock up hydrogen, it's a lot more annoying but if you're making a lot of it, it could be worth it. That's methanol.
Methanol is a liquid, it can be used in an engine, it can be used to make biodiesel out of vegetable oil.
To make methanol from hydrogen, you need carbon monoxide and/or carbon dioxide. The canonical way to make this is using charcoal, which can obviously be produced from wood.
Making charcoal into CO is straightforward if you use O2 to do it - you even have O2 coming from your electrolysis cell. This produces a lot of energy (you're burning charcoal), and you end up dumping it, but you can be a little more clever by adding steam to the reaction which adds an endothermic component H2O + C -> CO + H2. This has the benefit that you are making even more H2.
The methanol formula is: CO + 2 H₂ → CH₃OH
So for every 1 CO, you need 2 H2, so you need 1 mol of carbon, 1 mol of water, and 1 mol of H2 from the electrolyzer. When you add O2, you need to increase the amount of H2 you supply from the electrolyzer in proportion.
Unfortunately, the methanol reaction is annoying. Methanol wants to react at 100 bar (1500 PSI) and 280C, it *makes* heat as it runs, so you need to cool it.
So you have to get the temperature down so that the CO and H2 can be compressed. A SCUBA style compressor should work. Then once they're compressed, you put them through a heat exchanger with the exiting methanol. Since the methanol reaction is exothermic you only need to keep it from losing too much heat, you don't need to heat it.
The reaction wants to be 250-280C, but at this pressure methanol condenses at 250C so condensing out the methanol is not a huge deal, but unreacted gasses are going to end up at the methanol condenser and you really need to cycle them back around again. So I'm not sure if a circulator pump can be avoided. Obviously at 280C (just under the melting point of lead) and 100 bar of pressure, the last thing I want is moving parts and electricity, but I don't think it can be avoided.
Because the reactor makes heat, it will melt down unless you keep it cool, but this can be achieved by running water or steam over the condenser section. Some of that steam can be then used in the charcoal gasification section.
The syngas reactions are:
1. 6 C + 3 O2 -> 6 CO (-550kJ exothermic)
2. 4 C + 4 H2O -> 4 CO + 4 H2 (+524 kJ endothermic)
Combined that is:
10 C + 4 H2O + 3 O2 -> 10 CO + 4 H2 (-26kJ exothermic)
And the methanol reaction is:
CO + 2 H2 -> CH3OH
Or in this case: 10 CO + 20 H2 -> 10 CH3OH
So we need to supplement 16 H2 from our electrolyzer.
So to make useful numbers:
120 grams of carbon + 72 grams of water + 96 grams of oxygen + 40 grams of hydrogen makes 320 grams of methanol (0.4 liters).
2.6Kwh of energy to make 40 grams of hydrogen.
So for 1kg of carbon, we use 21.6 Kwh of energy making hydrogen, and we end up with 2.6 Kg of methanol (3.36 liters).
If we're making 100kwh per day, we need about 5kg of carbon per day to use them all, and we would of course get about 16 liters of methanol per day.
The charcoal demand is significant, making it from wood implies 4-5kg of wood per 1kg of charcoal, so 50 days a year of 100kWh/day production requires one metric ton of wood to produce the necessary charcoal. However this does make 800 liters of methanol (211 gallons).

Hydrogen electrolysis makes a lot of sense just below the boiling point of water, because you don't need pressure to keep the water liquid, and excess heat from efficiency loss can be recaptured to heat domestic hot water.
If you're prepared to run it at a higher pressure, you can save even more energy because you have less volume of H2 and O2 carrying heat away. But pressure in an electrolyzer makes everything more difficult. What could be plastic now must be ceramic and steel. Pressure vessels are costly and annoying. The bigger they are, the worse they are. If they need to have a removable lid, they're even worse.
Furthermore, the H2 compressor can be placed inside of the vacuum drying chamber so whatever heat it generates will simply assist in the drying process.

Hydrogen is a really nice thing to do with excess electricity. Electrolyzers are fairly easy to build and will take all the power you can throw at them. DIY electrolyzes are about 50-60% efficient, but they make something that's very high value. Hydrogen can be burned, used in an engine, or made back into electricity in a fuel cell. Fuel cells are expensive but it's 50% efficient conversion of H2 to power, gasoline engines are 30% at best.
At first glance, the hydrogen cycle seems extremely lossy, but all of the loss exits as heat. If you have a fuel cell in of your house and you run it in winter months when solar is not plentiful, the loss is all heat which you need in the winter anyway. On the generation side, the loss is also heat - and interestingly, you can make hydrogen at any temperature you want. If you're insane, you can run an electrolyzer at 1000C/1832F and the reaction will actually require 50% less electricity because the heat is contributing to the reaction. Just to give you a picture of what we're talking about, 1000C is about the melting point of copper, well past that of aluminum. Metal glows red. It's a real engineering nightmare.
Generally speaking, the value of heat rises as the temperature rises. Heat at 20C/68F can warm your house in the winter, but it's otherwise kind of useless. Heat at 100C/212F makes great domestic hot water, heat at 200C is into the zone where it can be used to boil water and run a steam turbine. So the higher the temperature, the more useful the waste heat.
Another fun thing about hydrogen electrolysis is that you can do it at any pressure you want. You do use a little bit more energy because it's producing gas bubbles with additional energy stored as pressure, but it allows you to generate hydrogen directly into a pressure tank if you want to.
Hydrogen storage is a more difficult problem. A 50% efficient electrolysis cell makes 15g of H2 per kWh. If you're storing H2 in bags, you have 89 grams per cubic meter so about 6 kwh per cubic meter. Over 3000 cubic meters of H2 from 20MWh.
Compressed H2 at 200 bar (3000 PSI, SCUBA pressure) is 15g / liter, conveniently the same number as 1 cubic meter in a balloon. So 200 liter "big tank" corresponds to 1.2 MWh.

2026-03-18 18:11:42 UTC

Was running some ideas w/ ChatGPT to try to find a solution that would work for storing excess energy from solar generation.
I was playing with the idea of having about 20 MWh of excess generation per year. Around 100kWh per day on good days.
Selling to the grid requires annoying permits and (depending on where) they don't pay well at all.
Batteries are like 1k€ per 10kwh, so they're good for a day or two of buffer storage, but not more.
Storing energy in water doesn't really work, you need insane amounts of water to store meaningful energy. Phase change materials like paraffin wax store more because it's latent heat of melting, but the size is still insane.
If you're thinking about storing heat, you probably want reversible chemical reactions, such as quicklime + water, or epsom salt + water which release a lot of heat, and then you recharge them by dehydrating them with heat. Epsom salt is probably the most interesting, it stores 190 kWh per ton and you can recharge it at 50-100C if you do so under vacuum. You can get close to these numbers using an off-the-shelf heat pump. But still, 20MWh equates to 100 tons of material, which is large and expensive.
An energy storage solution which is dumb NOT to pursue is vacuum drying. You can build a vacuum chamber and put lumber, garden produce, wood chips & things you want to burn, and you pull a vacuum in the chamber then use a heat pump to push heat into the chamber which causes the water to boil. The smart thing to do is run a pipe from the chamber to a condenser which is kept in cold water (pond, stream, swimming pool, etc) and because it's cooler than the chamber, it will condense out the water that is being vaporized from the stuff you're drying. This means you don't need to keep adding vacuum, just heat.
Tech Ingredients did this exact setup, except for vacuum distillation of wine. Once the vacuum is set, you don't need to add vacuum, just heat. And you only need to keep the hot side hotter than the cold side, and the reaction will continue to work.

And contrary to what some science blowhards will say, it does not cause a cataclysmic chain reaction resulting in the end of the world.
Humans have driven species to extinction in the past, nature restructures, life moves on.
Things like disease organisms, parasites, and mosquitos are some of the species that offer no benefit to humanity and SHOULD be classified as "desirable to exterminate".
But western culture doesn't consider itself capable of exterminating anything anymore - and moreover, some ghouls have taken it upon themselves to attempt to bring back pest species that were nearly wiped out in the past - such as the wolf.
Everybody knows that the soft men are making hard times, and things are going to get worse before they get better, but we can also take time to honor the hard men of the past who made the world a better place.

And if they go soft for even one second, the next guys are gonna come in and grab leadership away from them, and they're gonna be EVER MORE hardline than the last guys were.
And NOBODY can stop it, not the Americans, not the Israelis, and not the Iranians. It's a socio-political equivalent of the Dr. Strangelove Doomsday Machine.

Taiwanese hardware makers really want to create something great, Chinese hardware makers want to push the project through as fast as possible to a satisfactory completion (or at least not bad enough you complain).
Chinese and Russian developers are some of the most impressive in the world, they're natural mathematicians.
Eastern Europeans are also quite competent and easy to work with.
Germans show up prepared better than anyone, but then they overthink everything to death and it all ends up like the Berlin airport.
Frenchmen only want to work on "interesting" activities, if what you're doing is boring they won't have the stomach for it, BUT, they think like battlefield commanders when it comes to surprises and curveballs. They're some of the best I've ever seen at keeping a project on rails.
I don't really have any experience working with Japanese or American developers.

I don't know anything about Vietnamese or Malaysians, but I can easily imagine:
* Germans and Japanese would be excellent partners.
* Israelis and Dutch will beat you up in the negotiation but they'll come through for you.
* French and Belgians have their pride and cultural quirks but nothing you can't work through...
If you were to say Chinese were more difficult than Indians and Africans, then I would be surprised.

What other countries have you dealt with?

The thing that's weird about Americans (technically I am one, but culturally not that much anymore) is they have no respect for a meal as a meal, like if you convince them that eating soy powder out of a can will make them live longer and be healthier, they'd do it.
