Oof... well thanks for sharing but that's basically unusable for me. It neatly all packed in a 2MB file containing all assets, threejs, etc. I assumed it's based on a three.js template due to the `Rendered live with three.js · Drag anywhere to orbit the model` kind of showcase but unfortunately that's not linked. I also imagine the 3D models are more that primitives (at least the arrows showcasing the flow) but I don…

I mentioned elsewhere too. This was a one-shot thing that made me wow so I thought I share. You're kind with your comments but others are just hating it, even so I said 1. I don't know this motor technology and 2. It was a one shot experiment If I had time and making a polished web page was my goal I could probably do better but this was not the point!

I made it live and editable here: https://hallway.com/workspaces/f7cfb27c-0a0b-4ca3-9b28-cc7eb...

For family cars we need 4x 30-50 hp units. If the motor can weigh around 7 kg it can be placed directly on wheel. Adding durable brake discs (rarely used) and 2 inverters front ad back and we have the EV platform of the next 100 years

do we need disk brakes?

It would be awesome if they would implement a crude rule: no computers. You can use a computer to design the car--CAD/CAM/CAE are all fine--but no stored program computers are allowed in the race car. I think that would improve F1 tremendously.

Very funny idea. That basically means a carbureted gas engine, or a direct injection diesel with a mechanical governor and mechanically timed injection pumps - can't run a direct injection gas engine without a digital engine control unit, because the injection timings are much to precise to do mechanically. So, basically '60s Formula 1. Might be fun to watch. We'd certainly see some crazy engine designs and a lot of…

This is not accurate, the first production direct injection gasoline automotive engine was in the 1954 Mercedes-Benz 300SL. It's true, you probably won't be running piezoelectric injectors without computer controls, but there's nothing preventing direct injection.

But that would make it interesting. How many of the advances we've made in the past 75yrs could be accomplished some other way if you take the computer away? You don't need a computer to accomplish nanosecond timing. Maybe there's a clever analog way to run piezoelectric injectors.

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/

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.

I'm going to replace the differential and the automatic transmission in my truck with a 4-cylinder engine and an electric transmission.

Thanks for sharing. I wish it was a bit more interactive especially when there are parameters, e.g. "Widen the disc and torque rises with diameter cubed" I wish there was a slider to see that effect and thus maybe why there might be a sweet spot. Also I have "The Way Things Work" on my desk right now and can't help but wonder, could you adapt some of the pages of the book this way? It seems like exactly the kind of c…

Thanks but I'm aware of it, linked to an alternative just yesterday (but might replace by the InternetArchive one instead). A Web version would be so neat as we'd be able to link to pages, even states of the interactive explanation, rather than the whole thing but it's already great to have that basis.

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.

I think the cited weight loss comes from energy efficiency gains leading to less battery capacity needed.

So the engines have the same size of a disk brake?

That's incredible.
