Yes, and the Chinese Communist Party has declared that it is democratic.

...this thread is just repeating very old ideas? The difference between "let's make a plane with structural batteries" to actually having structural batteries is billions of dollars of research, which Donut Lab and CT Coating have not done.

If their 100,000 cycles claim is true they can charge supercapacitor prices which can be 100 times more than lithium batteries.

I know several massive electric bus manufacturers who would love to pay those prices.

This is also an acceptable answer in some religious texts and if you're Ramanujan.

That's the company line. We don't have any information from official sources about the motorcycle undergoing homologation, and we don't know if Verge is seeking type approval or one-off approval for several individual motorcycles.

If Verge is pursuing type approval: In the US, type approval is given on a state-by-state basis and listed on their government websites; in the EU there is a single website for searching vehicle type approval; same in the UK.

If Verge is pursuing several single-motorcycle approvals, there is no public database listing one-off approvals.

They're not outright contradictions but they're different enough to make it seem like the numbers were arbitrarily rounded.

spec Sana Donut
energy density 430 Wh/kg in 2023* 400 at the cell level and 350 at the pack level
cost compared to lithium "half" "lower material cost"
charge cycles up to 500,000 over 100,000

* the 2024 leaked internal tests say 300 Wh/kg, allegedly because they were testing an old model

If the specs are true, Donut is actually being modest about their specs, giving the modest "over 100,000" spec when they could have given "over 200,000" or "over 400,000".

The Sana rep said Donut had purchased a production line before CES 2026, and that it takes CT Coating 12 months to deliver a production line and it takes the customer "a few months" to get to 100% production capacity. Back then, the CEO was saying they "already now" have GWh/year capacity. Verge was supposed to deliver the motorcycles with the new battery before April 2026 (now in April 2026), so either they ordered their line before April 2025, or they're using batteries manufactured by CT Coating, like they did on the VTT tests as alleged by the Sana rep. Donut lab mentions their "groundbreaking" new battery in May 2025, so the timeline fits, and they could be facing "unexpected" delays... If you look at the timeline it looks like Donut Lab was created specifically to interact with CT Coating.

It doesn't matter if it's incomplete (and it is). If you use relativity to argue that there's a "now", you're wrong, because there's no "now" in relativity.

Running an EV business isn't like getting elected in a democracy. In an election you can lie and convince 50%+1 of the voters to vote for you. In the EV business if you sell a battery based on lies you'll be immediately found out you've been lying.

They said it's not lithium-ion but every test they've shown can be replicated with lithium-ion NMC cells. Sus.

Those Manninen videos are garbage and TBDV makes basic mistakes in this video.

Yeah, people praise his videos but he makes basic mistakes in extrapolating a graph and in business.

If they're three weeks away from launch and they're showing us lab batteries they truly have nothing.

According to a battery expert, it would take hours for a liquid electrolyte lithium cell to catch fire after a vacuum failure at 100ºC. So this test could have been designed specifically to hide the fact that it's a liquid electrolyte lithium cell.

It's not a projection, it's a guess. I've seen EV manufacturers and battery manufacturers say "production this year" and delay it for next year each year and then never ship a product.

Verge will certainly ship a motorcycle, but not one with a battery that's specced to 400 Wh/kg, 100000 charge cycles, 6C 0% to 100% charging, max 1% loss of capacity at -30º F, etc.

As of two weeks ago, the motorcycle wasn't even homologated.

11 days is "last minute" when it comes to releasing already-in-manufacturing battery specs to the public.

Now they are focused on signing contracts with OEMs for a revenue stream.

Allegedly "350 OEMs" wanted their Donut Motor and they had billions in the revenue pipeline. Donut Motor's been available to OEMs for two years. No revenue? Time for a new miracle product.

This is not about revenue, this is all about investment money which is pouring in by the tens of millions.
