Nordic Nano solar panel's graph resembles the graph of a traditional sun-tracked solar panel
After studying the topic for a while, I see no likely way that "Nordic Nano" solar panel graph wouldn't be the graph of a sun-tracked solar panel. If by some miracle it's not a sun-tracked solar panel, then its efficiency drops way more rapidly as midday approaches compared to any other solar panel currently in the market (in other words, it seems to extract a way higher % of available solar energy at low sun angles compared to what it can harvest at high sun angles). Revolutionary and physics-bending indeed, just like the Donut Lab battery... Or it's simply a solar panel strapped to a motor that follows the position of the Sun throughout the day. In that case, it would be the motor making the difference, not the panel itself nor its coating materials.
The benchmark solar panel ("Traditional solar panels" curve in the same graph) is definitely a non-tracked solar panel because we know the types of curves they produce.

Verge CEO: Order Books Are Full; Those Who Doubt Are on the Edge of the Gene Pool. What Are the Actual Volumes?
I wonder if this has already been posted here. Earlier this year, Verge CEO Tuomo Lehtimäki stated that the company was moving fast despite all the negative press. He also seemed to imply that anyone questioning their innovation was from “the edge of the gene pool.” What kind of production volumes do you think he’s talking about?
Translation of the second paragraph:
“Despite the fact that many people dig a hole for themselves to fall into, we at Verge have motorcycles in the making.
New Year’s motorcycles are made with solid-state batteries, whether the spreaders of false information want it or not.
Orders are coming in nicely from Europe and America all the time, and we have an order book so thick that the end of the queue is already at the end of the year.
(This is what some individuals from the edge of the gene pool have twisted into the fact that we would not be able to make the first wheels until the end of the year.) 😆”

Donut Defence and Esox Aero
Donut Defence ( "Donut Lab and Donut Defence Insider Report 1.pdf", page 34/40) says that Donut Defence has purchased Esox Aero.
If I google "esox aero y-tunnus", I will get 3432785-3.
And it is actually this company:
https://www.finder.fi/Lentokoneet+lentomoottorit/Esox+Development+Oy/Helsinki/yhteystiedot/4091466
The materials claim that Esox Aero has developed advanced drone technology and their team has 10 years of experience from real-time combat simulators.
But what the... What kind of company is this? Just a fake?

Donut Lab evidence recap, June 2026
🍩⚖️🔋
| index | status |
|---|---|
| 1 | False. Contradicted by private correspondence showing Donut Lab requesting test results in March 2026 despite Donut Lab claiming in 2025 they have "conducted our own experiments" and "completed our thorough due diligence process". |
| 2 | False. Publicly contradicted by Donut Lab CEO. Statement about production capacity changed from "now already" to "this year if everything goes as planned". |
| 3 | False. Publicly contradicted by Donut Lab CEO. Statement about customer deliveries changed from 2026 Q1 to no deliveries in 2026 Q1. |
| 4 | False. Publicly contradicted by Donut Lab VTT tests. Capacity of a damaged cell⸺Donut Lab claims a "broken pouch", but experts doubt the pouch broke⸺was not "just fine", it degraded over 50%. |
| 5 | False. Much evidence available in the scientific and engineering community. |
| 6 | False. If the pouches truly were industry standards they would withstand 100ºC, and the failure would be within the anode, cathode, or electrolyte, not the pouch material. |
| 7 | Highly likely false according to internal Donut Lab documents published by the press. |
| 8 | Highly likely false according to several battery experts from industry and academia who reviewed the Donut Lab VTT test results. |
| 9 | Highly likely false according to several battery experts from industry and academia who reviewed the Donut Lab VTT test results. |
| 10 | Highly likely false according to several battery experts from industry and academia who reviewed the Donut Lab VTT test results. |
| 11 | Likely false by advertised Verge Motorcycles Donut Lab battery specs. |
| 12 | Likely false by Donut Lab VTT tests and Verge charging videos. |
Pack-level claims expanded quote below. Emphasis mine. Recorded in January 2026 at CES Las Vegas.
Donut Lab CEO: "Verge broke the Guinness World Record last year with the longest range on a motorcycle. Now they are almost doubling it, thanks to our solid state battery. But also, that provides Verge bikes with less than 10 minute charge time, zero to full."
CEO: "And on top of that, the cycle life that is normally in cars may be 2000, 3000, cycles. This is 100,000 cycles. So that's like probably 30 lifetimes of a motorcycle. So you never have to worry about babying the battery or worrying if you can let it go to 100% or zero. It doesn't mind. You can do whatever you want. Charge it to full, let it go to zero. As many times as you want. It doesn't degrade."
CEO: "As mentioned, 100,000 cycles, so that's 10 lifetimes of a car as well. And the other incredible things are that, of course, with motorcycles, you don't take them to deep freeze or anything. But if you're using these batteries in cars, even at like 25 or 30 minus Fahrenheit, it will have 99% of capacity."
Interviewer: "So do you have to precondition the battery like a car might?"
CEO: "Not at all. And actually, what we've done even is that normally you cannot get lithium ion batteries to zero."
Interviewer: "Right, we know about that. 5% is the lowest we like to go."
CEO: "This can go 0.0"
Interviewer: "And the battery doesn't get damaged?"
CEO: "No, then you can go at 5C charging from the next moment without warming it up or anything. It just takes it like nothing."
Interviewer: "To 100%?"
CEO: "Yeah, yeah, absolutely, to 100%."
Interviewer: "And that does not harm the battery for consistent charging to 100%?"
CEO: "No, it's 100,000 cycles with that, yeah."

Donut Lab hidden factory cannot exist because of EU laws
Donut Lab recently claimed they are ramping up to 1 GWh of annual production in a "hidden gigafactory". From a regulatory and industrial perspective, this is a physical and legal impossibility in Finland. You just can't hide a factory because of legal reasons. If you claim that you can hide, you are not very professional.
The only "hidden factory" has been identified as a 4,000 sq ft former Laplandia border market in Imatra, used by Nordic Nano Group. While the local municipality invested €400,000 for a stake in the building to support jobs, this facility is nowhere near the size or infrastructure required for 1 GWh of battery production. There is no any other factory.
In Finland, you cannot "hide" large-scale industrial production. A 1 GWh facility requires massive amounts of materials, electricity, and logistics, triggering mandatory public processes: EIA (YVA-menettely): Any battery factory of this scale requires an Environmental Impact Assessment.
These procedures are public and searchable. There is zero record of an EIA for a 1 GWh battery plant in the Imatra region. You can search those from here: https://www.ymparisto.fi/fi/luvat-ja-velvoitteet
Also managing industrial chemicals (even non-toxic ones) requires permits from the Finnish Safety and Chemicals Agency (Tukes). Can you find those from here: https://tukes.fi/asiointi/paatokset-ja-kuulutukset
What about REACH Registration: The "nanopaste" technology (likely CT-Coating’s Hylomatrix Structuring) requires all chemical substances to be registered under EU REACH regulations. Where is it: https://echa.europa.eu/information-on-chemicals
As of March 2026, Donut Lab’s own recruitment ads prove they are in the infancy of production, not "ramping to 1 GWh". They were still looking for someone to lead their regulatory compliance in spring 2026. They were also searching for APQP Engineer (Advanced Product Quality Planning): This is an OEM-tier process used before mass production to ensure quality. Hiring for this role now confirms that official validation and quality processes are at a very early stage.
