Maybe going directly to recycling the lithium from an only moderately degraded lithium battery is helpful to the price, but the details might be important there.bjn wrote: ↑Wed Jan 04, 2023 12:14 pmSodium batteries could work great for static storage applications. So all those grid attached peaking shaving and stabilisation batteries should get cheaper, as well as your domestic PowerWall equivalents. This would free lithium to be used where having lightweight batteries is much more important. This should make lithium batteries cheaper for those applications than it would otherwise be if there were no sodium batteries.
https://www.nytimes.com/2023/01/17/maga ... -musk.html?We parked at the spot where he hit the police S.U.V. four years earlier [when the Tesla was in self-drive mode]. There was nothing special about the road here: no strange lines, no confusing lane shift, no merge. Just a single lane of traffic running along a row of parked cars. Why the Tesla failed at that moment was a mystery.
Eventually, Key told F.S.D. to take us back to the cafe. As we started our left turn, though, the steering wheel spasmed and the brake pedal juddered. Key muttered a nervous, “OK. … ”
After another moment, the car pulled halfway across the road and stopped. A line of cars was bearing down on our broadside. Key hesitated a second but then quickly took over and completed the turn. “It probably could have then accelerated, but I wasn’t willing to cut it that close,” he said. If he was wrong, of course, there was a good chance that he would have had his second A.I.-caused accident on the same one-mile stretch of road.
[...]
We approached an intersection and tried to make a left — in what turned out to be a repeat of the Laguna Beach scenario. The Tesla started creeping out, trying to get a clearer look at the cars coming from our left. It inched forward, inched forward, until once again we were fully in the lane of traffic. There was nothing stopping the Tesla from accelerating and completing the turn, but instead it just sat there. At the same time, a tricked-out Honda Accord sped toward us, about three seconds away from hitting the driver-side door. Alford quickly took over and punched the accelerator, and we escaped safely. This time, he didn’t say anything.
It was a rough ride home from there. At a standard left turn at a traffic light, the system freaked out and tried to go right. Alford had to take over. And then, as we approached a cloverleaf on-ramp to the highway, the car started to accelerate. To stay on the ramp, we needed to make an arcing right turn; in front of us was a steep drop-off into a construction site with no guard rails. The car showed no sign of turning. We crossed a solid white line, milliseconds away from jumping off the road when, at last, the wheel jerked sharply to the right, and we hugged the road again. This time, F.S.D. had corrected itself, but if it hadn’t, the crash would have surely killed us.
Tesla and production problems are almost a tradition at this point. You could think its because they are pushing innovation barriers or (as I do) that they've worked out over-promising and under-delivering has fewer downsides than up. Will be interesting to see if enough people actually want Cybertruck - hard to judge from a European perspective but it looks like a potential huge white elephant and I really wish they'd cracked on with the smaller model instead.Woodchopper wrote: ↑Thu Dec 21, 2023 7:49 pmTesla has big problems with battery production: https://ca.news.yahoo.com/austin-proble ... 07306.html
There are quite a few micro mobility options, the Fully Charged Show cover them fairly regularly. The Microlino one looks funTopBadger wrote: ↑Sat Dec 23, 2023 3:28 pmYou'd think smaller cheaper ev mobility would be a bigger part of the conversation at this point.

There's not a lot of room in there. I'm not a big guy (6 foot) and wouldn't claim to have wide shoulders (average, I suppose), but according to their specs I'd have about 1/2" of head room and 2" of shoulder room. That'd lead me to feel cramped after a short while, and many men might simply not fit properly (before anyone accuses me of being male-centric, all the website pictures show men driving, one with a woman in the rear seat).TopBadger wrote: ↑Sat Dec 23, 2023 3:28 pmYou'd think smaller cheaper ev mobility would be a bigger part of the conversation at this point.

Yeah - looks on the small side but probably fine as a daily commuter / station vehicle for the multitude who travel alone with just a backpack / briefcase.Martin_B wrote: ↑Sat Dec 23, 2023 11:30 pmThere's not a lot of room in there.TopBadger wrote: ↑Sat Dec 23, 2023 3:28 pmYou'd think smaller cheaper ev mobility would be a bigger part of the conversation at this point.

The range is fine for a city run-about, but the luggage space is a small esky (coolbox) size, so not necessarily suitable for shopping unless you do grocery shopping daily and never buy more than one item of clothing at a time.
I've got a Duster. It's cheap - I don't expect Volvo standards on a cheap car. But five months to get spare parts. !!
Long delivery times for car spare parts has been a very common over the last few years.
In Texas over 25 years you could reasonably add 2-4 hailstorm with hailstones in the neighborhood of 3/4"+bjn wrote: ↑Sun Jan 09, 2022 6:56 pmAs I said, might not be the best use of a solar panel, unless they were stupidly cheap. I used to park a car on the street in suburban Sydney, which would be a better proposition thank parked on a street in urban London.
Solar panels do need to be just as robust as a car roof, being put on roofs and left in the rain and all. Current panels have a lifetime of 25 years or so, which means they are more likely robust than a car roof.
Looks like they need to be made noisier - to protect pedestrians.During 2013–2017, casualty rates per 100 million miles were 5.16 (95% CI 4.92 to 5.42) for E-HE vehicles and 2.40 (95%CI 2.38 to 2.41) for ICE vehicles, indicating that collisions were twice as likely (RR 2.15; 95% CI 2.05 to 2.26) with E-HE vehicles.
They have been, haven’t they? I think the rules about them emitting noise at low speeds are since 2017.bob sterman wrote: ↑Wed May 22, 2024 5:23 amhttps://jech.bmj.com/content/early/2024 ... 024-221902

Another factor is that EV/HEs might be that they have longer braking distances. I've been unable to find out whether this is in fact the case, there seems to be some disagreement about it.bob sterman wrote: ↑Wed May 22, 2024 5:23 amhttps://jech.bmj.com/content/early/2024 ... 024-221902
