Word, I love this.

I strongly agree with @Cenotaph@mander.xyz , this is like a fun comic, made all the more fascinating by how accurate it relays what’s going on behind the technical curtains, behind which only a few see, and yet fewer understand.

Love this city.

Oh damn, even I misunderstood the original phrase. “Promised, screwed” but even that doesn’t quite get it. Hey I’m not a copywriter lol

Promised, not delivered.

Gimme a fuckin break Mike.

No, it doesn’t solve the wear problem, that’s precisely my point. It moves it, and at a monetary cost.

Easy example of adding complexity to help meet a goal, geared turbofan engines. Simplicity and reduced short term cost? Antithetical. Long term costs thanks to efficiency savings? In spades.

I still see parroting of seeming truisms versus actual understanding on choices made, based on changes observed since the 70s onward. “Solid state always beats mechanical”, for instance, something that _seemed_obvious in the 70s and 80s. This makes you out to be around what, 55 is my guess.

The tribal knowledge of implementation details have changed since the solid state revolution, some applications of solid state are still past the edge of solid state capabilities if your goal is cost reduction. That was Eberhard’s intent, and what a geared motor would help solve, never mind the expected initially high costs.

How/what kind of motor is built dictates its favored unloaded RPM, haven’t you seen exposed A/C motors spinning fans for e.g. pumps or Aircon condensors? 20k rpm as an argument?? Jesus. I read between the lines and see your actual understanding of the matters.

So listen, I’m not interested in converting a zealot. I personally also believe solid state is the way to go for controls and other parts of a system, but the difference between a junior and experienced engineer when it comes to production at international consumption levels is knowing what tools are appropriate, and where, in that system. A lot of the rest of your argument text is a red herring, I encourage you to reread it and discard it as I have.

I remember reading about that too. I wonder where the truth lies in all this.

Oh, just lol. I can see the nuances of the engineering choices aren’t getting through here.

That very choice is a critical part of why there aren’t many cheap EVs on the market. If you’ll recall, Eberhard was trying to keep costs down so that ordinary folks could afford the vehicle. Smaller motor plus gearbox costs less and reduces other costs as well. Elon changed the engineering goals, forcing the roadster to be priced yet higher.

A large, custom motor “solves” the problem inelegantly by replacing an undersized mallet with a sledge, as you’d expect from a moron. Correspondingly larger IGBTs, larger switching losses, more battery capacity lost to needing to parallel vs series for feeding the larger motor a lot of current. There were and yet remain many downstream negatives to that decision.

As for the rest of the market following, why are you surprised that the same market which kept saying “10yrs away” also couldn’t be imaginative enough to innovate?

It’s obvious you don’t want to shift from your position either, the funny bit is that at least one of us here has evaluated merits vs problems with any technical background. Keep on drinking that corporate Kool aid.

Indeed.

Yawn. Hello ad hominem, early on. Lots of unnecessary verbiage.

The rest of your argument is both trite & false, and again reveals a lack of engineering prowess/understanding. It’s not always intuitive, so I don’t blame you much. Quick example: gears add contact friction, but also significantly reduce bearing loads on the motors, among other things. You trade some efficiency for better lifetimes on the parts experiencing the most pressure. Further, Teslas still have a gearbox, and even as a single stage system, they still experience failures. “No part” eh?

If there was anything to learn from reading a carefully manicured blog where honesty isn’t guaranteed, it’s that there wasn’t enough of a commitment to getting it right, iterating takes time, which is still why I won’t buy one of those styrofoam-padded shitboxes. Still buying an EV, just one that was actually well designed.

That you feel attacked by my laughing at your conclusions, well… Cry about it.

You can make em out of waxed cardboard, in fact…

E: in Minecraft

As seems your custom, lotta useless verbiage.

Exactly how I felt about it as it was happening, fucking stop talking about his bullshit and talk about the positives of any alternative players! We know he’s bad news!

I’ll be surprised if he makes it a year.

100%, I hated every minute of my layover wandering that shit-quality SimCity attempt, the bubble popped real fast once I talked to some locals.

I can’t wait for the sand to bury that cruel slave labor shitberg.

Damn were you just waiting for the opportunity to drop this on someone? Lovin’ this stuff, got a couple of shirts already.

Psh, those low quality NYPD shitrags never gave a fuck about integrity. The uniform is just a costume.

Anyone in my circles who’s had to fully interact with our US healthcare has, at minimum, said they understand the motive.

I don’t give a shit.
