> It is nanoprinted and trivially scalable. Nanoprinted snakeoil - infinitely scalable. Good enough to grab 3M€ public grants and some more from gullible private investors. Honestly, if they had the tiniest proof of their claims (400Wh/kg, 5min 0-100%, operating temp -30°C to 100°C, no Li/Co/Mn and somebody looking at the production and taking the output to the test) they would be absolutely drowned in money to the p…
This is an honest question for my understanding: how would a scam like this work? Take investor money and spend it on yourself? Or give yourself an outrageous salary?
They "lie" but it's helping the company to get more money because they basically solved it in the lab.
Independent of were they are it will Help them to get more money.
And it either leads to success or firing and lost capital

#273If this is true, it's possible that the technology is from Nordic Nano. That would at least explain how a motor/software company could pull a battery out of thin air: https://www.donutlab.com/nordic-nano-investment/ Their chief scientist is working on solar-powered hydrogen production, which seems fairly unrelated to solid state batteries: https://www.nordicnano.co/chief-scientist-bela-bhuskute-will...

Yes, it is from Nordic Nano. It is nanoprinted and trivially scalable. Free of lithium, cadmium, lead, and cobalt. Uses abundant raw materials free from geopolitical constraints. https://yle.fi/a/74-20118784 Factory in Finland, started around Q3/2025. https://yle.fi/a/74-20180376 Verge Motorcycles bike with the new battery at CES, apparently at West Hall 5658.

The Nordic Nano connection is strange. Here's their web site.[1]
They claim to make solar panel coatings, solid state batteries, and do something involving hydrogen. This is all done from a little metal building in a small town on the east coast of Finland near the Russian border. There's no detail on any of this technology.
One Youtuber thinks this is a capacitor, not a battery. But that would require a dielectric orders of magnitude better than anything known.
Donut won't talk about either the chemistry or the manufacturing. The only thing they showed at CES was one pouch cell hooked up to a charger at 4.2V, drawing current. Everything else was a 3D printed mockup or an existing electric motorcycle.

#274This is a fraud.
The magnitude of their unsupported claims is a good indication but I suggest checking out their LinkedIn. They employ a handful of people none of them with a chemistry background, most of them don't have an engineering/science background at all.
The final data point: here's the CEO of Donut Lab also announcing "The World's First True Artificial Superintelligence" in a company where supposedly he is the chairman: https://www.youtube.com/watch?v=ilgJKjiDLV8 (for contrast here's Donut Lab's video announcement of the SSB https://www.youtube.com/watch?v=Y-aPS2AwMbc).

Not sure why you’re being downvoted, this is objectively true. Saying this as a German, where the economy is the worst it’s been in decades and our federal government acts incapable at changing this so far. Anyone who’s been to China, Israel or the US will be familiar with the pragmatism and, more importantly speed things happen in these places. I do like Europes rules on civil liberty and privacy protections, but le…
It's true but the regulations are hardly insurmountable. As a German you may have heard of such European manufacturers like Volkswagen, kuka and reinmetal As a Swede I can add Saab(aeronautics, not the defunct car manufacturer), Scania, and IKEA to the list. Far from a exhaustive list, but proof positive that manufacturing can in fact happen under European regulations.
LEGO, Siemens, ABB, BASF, Bosch, Nestle, Airbus... you can keep doing this for a very long time.

You can see in the picture the boiler is taking the load of the machine. There is no additional chassis. That's less frame than a Ducati has between the front and rear wheels. Without speaking to the wisdom of stressing batteries mechanically, the idea of using drivetrain components as structural members of a vehicle is as old as self-propelled vehicles. Hell, even a chariot sees the horse taking a part of the vehicl…
Merely "using drivetrain components as structural members" is not a monocoque, but it's a start. You're correct on the chariot. A monocoque incorporates ALL components as stressed members so even a classic Lotus Esprit would fail that strict definition given that both hood and trunk are free-floating cantilevers, but point taken.
Oh, I see.
I was responding to the more general statement:
>You do not want the stressed members of any structure being a salient contributor to its power-train. Not related, see mammalian, reptile, fish, and insect physiologies.
A steam traction engine is certainly at a different level to an F1 car, in both performance and engineering.
On the other hand, I think adding dynamic load to a steam boiler is riskier than doing so to an internal combustion engine.

I wouldn't call it an outright scam. But yes, you pay yourself a nice salary, travel around the world to meet potential OEMs, you may fly in private jets, you stay in fancy hotels, you have business meetings in Michelin star restaurants. The motorcycle is real, you can buy it. I worked for a company in Germany in 2024 and the CEO was quite open about using public grant money as a free gift. The company wasn't build a…
> The motorcycle is real, you can buy it.
Pretty major point of difference though isn't it? They claim this will be out there in Q1 2026, giving a chance for sceptics and industry professionals to tear it down. If this is really the long con, they'd at least give a little time for the cheques to clear before their wild claims could be assessed?
The other possibility is that they have very little moat with this new battery tech, because it's so easy to manufacture. Being the first mover might be their only play, and it's only a matter of time before someone else figures it out (or it leaks).
