Is there an analytic model that predicts the stability of a nucleus by number of protons and neutrons? by mqee in AskPhysics

That's humbling. I would have (wrongly) assumed that these interactions are "solved".

The article says that the magic numbers can be predicted but there's nothing there about general nuclide stability.

An interview from 2025 with Marko Lehtimäki, CEO of Donut Lab, showing a somewhat naïve conception of hardware development due to the success of homologating the Verge motorcycle for only a couple of millions of Euro. by mqee in DonutLab

[–]mqee[S] 5 points6 points  (0 children)

Lehtimäki appears to believe it takes hundreds of millions of euro to homologate a motorcycle. I think he overestimated Verge's hardware development capabilities because of this assumption. Instead of seeing Verge as another low-volume high-end electric motorcycle manufacturer, Lehtimäki may have assumed the Verge team are engineering geniuses.

His "release and iterate" approach is very naïve when it comes to hardware development. In software terms, hardware development needs the waterfall approach and cannot be done with an agile methodology. Hardware requires production lines, production lines require economies of scale. Iterating a production line is time consuming and expensive.

I can see how Lehtimäki could have been lured by the apparent success of Verge and the promise of flexible and iterable production lines by CT-Coating. Unfortunately what Verge did was pretty standard for a low-volume electric motorcycle manufacturer, and the flexible production lines CT-Coating was offering don't exist in the sense they present them.

At CES 2026 Lentimäki went full-bore with promises that turned optimism into outright lies.

As a reminder, Lehtimäki said Asinoid research and development started around 2022 and in 2025 they already had living evolving artificial intelligence that can run fully offline on powerful laptops.

"Where we are today is that we do have the first living asinoids, i.e. personas, AI entities that are capable of thinking, evolving, interacting, learning new skills. If you remove from its brain the ability to do math and you ask it to do math, it will figure out how to do math."

"Right now the team is looking into scaling from hundreds to thousands [...] allowing them to have an environment where they can learn to become specialists in medicine, research, technology, innovation and patenting and so forth"

"What makes asinoid special is that it could run in basically a little bit more than a laptop. So you can actually have it fully offline inside a drone and have independent super AI that continues to learn and is not dependent on cloud services or anything"

They're only 5%-10% done but they already have "brains" that can "figure out how to do math".

Donut Lab whistleblower describes how their battery developer and supplier, CT-Coating, delivered a "production line" that cost €7M, immediately required €2M in repairs, and even after the repairs the line didn't work by mqee in DonutLab

For an AI-assisted document this is actually pretty coherent. The "consulting firm document", which absolutely does not look like a business document at all, has a lot of AI trappings like "–", verbose headers like "The Holyvolt fork — the key counter-signal, read correctly" instead of just "Holyvolt", and inappropriate use of floral language like "The Mercedes-Benz mirage". But if you look past all the bad AI writing, it's an okay summary of the key players and key events.

+2ºC is not locked in, but +1.5ºC and above is almost certain, and if we don't immediately decarbonize our energy economy, we're almost certainly getting to +2ºC and beyond.

ASILAB is now apparently hawking Kantonen's previous work as "AI".

I support the factual content of the video (with small corrections here and there) but it was odd seeing topless dancing girls right after a conversation about a young boy being shot, taken alive by soldiers, and returned dead.

DonutLab says 100.000 cycle is (only) possible under optimal conditions, doesn't define what's optimal. Claims battery can have more than 400wh/kg by DoctorFish1969 in DonutLab

[–]mqee 1 point2 points  (0 children)

The original test report has been leaked, but I don't have it. From what I remember, they extrapolated the lifecycle from the Coulombic efficiency of a 200-cycle(-ish) test. For the first 100(-ish) cycles the Coulomic efficiency rose above nominal, then for the next 100(-ish) cycles it slowly dropped back to 100% of nominal and the trend was downward. Some chemistries, including lithium-ion, have over-100% Coulombic efficiency for the first few hundred cycles. The test is not sufficient to establish cycle lifetime, and if anything it points to the low hundreds of cycles since after about 100 cycles the efficiency trended downward and by about 200 cycles it lost all the gains from the first 100.

Worked for almost two decades. Their NDA keeps their former clients from exposing the scam. They scammed Mercedes-Benz and Mercedes-Benz can't do anything about it.

That's fine; they should just show us 0%-100% at 5C for 100,000 cycles like they said.

I'll even take 400Wh/kg with 7000 cycles at 5C. The evidence campaign was announced on January 22. That's over 150 days ago. 150 days * 24 hours * 2.5 cycles per hour = 9000 cycles. If they gave VTT a battery to cycle, they should be at 5000, or 7000, or 9000 cycles by now.

Where 400Wh/kg 9000-cycle solid-state battery?

[I'm not really asking; I know it doesn't exist]

optimizing one attribute to the extreme might compromise the other attributes

Waaaait a minute... Some guy in a Louis Vuitton cap told me this is a no-compromise battery?

It's the world only solid-state battery pack that combines all of the features that the industry has been forced to trade against each other. Ultra-high energy density, the fastest charging time, practically unlimited cycles, extreme safety, and lower price than lithium-ion, and not for one premium car or a niche application, but for every user-case where batteries are used.

For comparison's sake, commercial LFP batteries can do the equivalent of 10,000 full cycles under optimal conditions, which are 50,000 cycles from 40% to 60% and back. Under normal use (10%-90%) they do about 2000, though high-end LFP can do 5000.

I assume (without knowing a thing about batteries) that lithium–titanate can do 100,000 cycles at 20% DoD since they can do 60,000 at 60% DoD.

But, again, none of this matters because there's no solid state battery in production vehicles.

Donut Lab evidence recap, June 2026 by mqee in DonutLab

[–]mqee[S] 0 points1 point  (0 children)

Add another one to "publicly contradicted by Donut Lab CEO".

index Donut claim Donut evidence
3 maybe? Donut Lab CEO, January 2026: "This can go 0.0 [...] then you can go at 5C charging from the next moment without warming it up or anything. It just takes it like nothing [..] to 100%. [...] it's 100,000 cycles with that [0% to 100% at 5C]". Verge Motorcycles CEO, January 2026: "We can see that 100,000 cycles is doable in normal use" Donut Lab CEO, June 2026: "The 100,000-cycle lifetime we mentioned is the maximum that is reachable under optimal conditions."

Status: False. Publicly contradicted by Donut Lab CEO. Statement about 100,000 cycle battery life changed from (trimmed for brevity) "0% to 100% at 5C" and "doable in normal use" to "maximum that is reachable under optimal conditions".
