Tangential, how much regen can this system support? For example, can a car with 200kW propulsion have a 400kW regen (Tesla has upto 65) and are cost effective like friction brakes?
Am I reading you right that breaking power (that you want to regenerate in the system) >> speeding power? Obvious now I come to think of it, and still pretty nifty new thing learned if true!

> UK is by far the best country to raise venture capital in Europe For late stage? Continental Europe has its banks and industrial policy. America and China have their deep pockets. Scaling out of the UK is incredibly hard, doubly so post Brexit, that’s why they sell early.
I think continental Europe has nothing on the UK when it comes to banks and financial markets. The UK has the deepest pockets in Europe because it is a hub for global capital. Brexit does not seem to have made a difference: https://www.uktech.news/funding/late-stage-funding-surges-as...

Mercedes acquired Yasa (UK) couple of years ago and now getting up to the speed in the production. Here is a nice video that explains axial flux motors with a factory visit https://youtu.be/B2Hl4c1iZK0?si=VfDYARyuaPVj1nKm They are so, so, small.
I was curious how this thing works and asked Claude to visualize it -- mostly to see how good Fable is and I have to say, what it made was good enough for me to get a gist of it. Posted it here https://azimi.me/axial-flux-motor-explainer/

Click "More" and scroll down: "In contrast to conventional radial flux motors, the electromagnetic flux in an axial flux motor runs parallel to the axis of rotation. The key components are arranged in a disc‑shaped layout: two rotors sandwich the stator from the left and right. This design enables an especially compact motor architecture, high power and torque density, and new freedoms in drivetrain packaging. In the…
Really the kind of thing that should be earlier in an article about… that very thing the reader is wondering about, but maybe we arent the target audience?

do we need disk brakes?
Yes, you must be able to stop independently in the case of some kind of total power failure in the drivetrain.

You don't. You didn't know before either. The difference is trust. How do you trust it as much as you do the hypothetical humans making such representations? That's up to you.
I think humans develop expertise and brand names and get called out when they make mistakes and if they are too wrong, their reputation is damaged. This doesn’t seem to apply to AI for some reason. It keeps generating incorrect results after incorrect results, yet people continue to trust its output. I don’t know what to make of this.
Take a look at the Forbes billionaires list and some of their statements. Or maybe at the politician fact checkers. If only being wrong damaged reputations.

Number 1 problem is battery weight though. Not electric motors. I have a 84 w123 300D, and would love to add some more power to it. Lightweight hub motors would be great, but any decent size battery would be at least 200lbs+, which is hard to do on a old chasy.
its less hard than you'd think unless you're really going for long range. for my sailboat I am getting rid of a 300lbs diesel and a 30gallon fuel tank with a 45lbs PMAC. That means I have opened up about 465lbs for batteries. Now, with a sailboat you're never truly out of range -- but the point stands : these things are so much lighter than ICEs on average that there is a lot of opportunity even with battery weight a…
BYD can be lighter because they skip on safety gear and proper structural elements - in my experience.
Their motor is pretty cool. So are lots of other ideas and concepts. This is supposed to be about production. Arguably, the coolest thing about Yasa is the machines and process they have created to produce their motor in production quantities.
It disappoints me when an article promises to be about production but seems more to be a press release about the product.
I wish them well and would be excited to learn more about their actual production capacity.

I asked mythos to make a "The Way Things Work"-inspired version. Published: https://banagale.com/the-way-the-motor-works/ Source: https://github.com/banagale/the-way-the-motor-works It lacks cave people but has the woolys.
I’m sure folks would be interested even in a blog post comparing just this process with different Anthropic models if that’s something you do and need a content idea. :)

Every plausibly cool electric car innovation leads me to the same thought: “5-10 years from now, the restomod potential will be wild once these come down in cost.” For this, I am imagining retrofitting a Pontiac Fiero to reduce as much weight as possible and see if extended flight becomes possible.
