This guy has ice storage:

Batteries should see drastic declines as well. $300 is already considered a steep price even though it is the all-in price. We are talking about $50 at the cell level for LFP chemistry soon.

Or just cancel almost all meetings and do async communication. Works great.

I suspect the partial in-office/wfh arrangement will be fairly rare. Office space is costly to use only 2 days a week. Companies can do hoteling but it breaks down when you have very technical employees who like very particular desk setups (multiple monitors, chair positions, special keyboards/mice). The more common arrangement will probably be mostly WFH but meet up occsionally in some per-hour rented office for collaboration. Sucks for WeWork to have blown itself up before this :).

Thus the charging curve should be better and not worse.

Wawa (gas station chain) has already opened the first store with only charging and no gas in Northern VA. It’s basically a mini-mart with Tesla Superchargers.

Tesla Supercharger V3 can get to 250kW at 400V. The charge cable is liquid cooled due to the massive current which does add some cost.

V2 Supercharger limitation does appear to be the heat in the cable and connector. We know the battery can accept more current but it is limited due to the cable.

Your link doesn’t seem to point to anything.

Whats wrong with Peter Baker?

Yes, I saw that interview and the follow up. He can talk very in-depth about the engineering of the cars as well but he is _Chief Engineer_ at SpaceX. I don’t think people quite understand this when they call him a businessman, promoter or marketing guru.

We are just used to this for “computers” because of how the industry evolved but it really is the exception and not the norm if you think about it. Even for early cell phones and pdas most ran their own OS and didn’t seperate the hardware and software layers.

I disagree but will likely get downvoted on HN as this communtiy does not really reflect the huge set of customers Apple is building these devices for. The Mac is for us. iDevices still for the most part target a broad swath of users (despite the pro moniker) and have to be easy to use and as secure as possible.

Offically suporting sideloading will lead to what we have on the Mac, an official app store that is barely used and compromises the security model and user experience for many major apps. If you give an official channel to bypass Apple policies people will use it for everything. A major part of the security model for example is a third-party (Apple) being able to nuke abusive apps. Also enforcing compliance with certain UI guidelines as the devices evolve keeps things very easy to use. Its possible to have some of the things for sideloaded apps but more difficult to control.

We have over a decade of data and experiences with this Sandboxed approach. The fact that you still use an iPhone/iPad over Android means you are tacitly agreeing with the approach.

I am not defending Apple here but perhaps they intend to make this a public entitlement or even an official API but they are working with Zoom to test it first.

We know Apple gives testing priority to certain developers, they mention it at practically every presentation they do. Granted those are usually for NDA’d features for making demo-only apps.

Tesla publishes data about their own cars with autopilot engaged vs. disengaged. This should get rid of a lot of the variables that you cited.

No there are issues with the EA chargers being from different vendors. This article is really good and gets into it:

https://insideevs.com/news/389891/exclusive-interview-electr...

“Electrify America currently uses units made by ABB, BTC, Signet, and Efacec. Every time they have a software or hardware update, it has to be done on all four brands, and they don't always all work the same afterward. Fitezek has to work out the kinks with all four partners and they all respond on different timelines. I could see that this was clearly a pain point for him.”

Not only that but you have much more space available for the batteries and larger cargo carrying capacity so you could really experiment with some crazy designs.

I belive this is mostly in the EU where they already have the CCS2 connector. I have not yet seen any North American car with a Tesla connector except _maybe_ the new prototype Aptera.

While the house may have a 100amp setup, the actual utility from the pole is probably capable of 200amps. Changing out your main breaker to 200amp is not that hard but may cost you an additional ~$1,000 for parts and labor.

Actually recently Urban SC development has seemed to come to almost a halt. Even in Urban settings it seems they much prefer to just put in the V3 cabinets with the 250kW max pedestals.

They can if they work with Tesla (and share development costs) but so far none of them have.

I agree it should be standardized and we should choose the Tesla connector which I belive is an open design.

They are now getting into the density game in a lot of markets which is very exciting. For example they are putting Superchargers at every single rest stop in NJ along I-95 (I think its like 8 total in a couple hundred mile span). With the density you can really optimize your charging since charging is very very fast at a low state of charge.

Its weird they never really put that tech into the large trucks or SUV’s they sell. It could have had a much bigger impact there.

At least for Tesla, around the eastern seaboard, this is not the case. The rest of the EV world will eventually converge to this state as the infrastructure is built out.

The leading edge of EV’s (Model S Long Range) now have over 400 miles (300+ to 80%). I-95 for example in NJ and CT have 250kW peak Superchargers spaced every 20-30 miles or so. Its not quite the same as ICE still but it is getting very close. I can imagine the technology will be there in 2-3 years and it doesn’t require any sort of solid state battery technology.

I follow the development of the stations pretty closely. It is much much much harder than you think it is. Some stations take well over a year from permitting to lighting them up. Tesla has also made deals with a lot of businesses and states to put them on highway rest stops. The other charging stations are spotty at best. I live one mile from the Electrify America HQ. Even the station at their HQ is iffy and I had issues with payments on it.

Also Tesla has two full production lines for the station gear. One in Shanghai and one in Buffalo NY. Electrify America is a hodgepodge of 4 different suppliers gear.

lol if you think trucks are primarily driven by contractors or farmers. You should visit the south, trucks are most definitely used as commuter cars.

The total amount downloaded or uploaded really isn’t the right thing to care about. They just need to manage capacity on their network on a per cell basis and then wherever they aggregate to. I think if every user in a given region was completley saturating their 100Mbit/s link all at the same time, yes they would melt. Fortunatly as they onboard new users they can monitor capacity and daily activity and make sure they cap the number of users in an area before they have capacity issues. As usage patterns change over time (and WFH becomes more prevalent due to covid) they will also have to keep up with the demands for more bandwidth.

SpaceX is similarly doing this with Starlink providing a 100MBit/s+ home internet link.

Click was nice. A lot of the newer JS frameworks are basically client side replicas of it.

Neither of those are unbiased. In fact they are constantly biased against Tesla and towards legacy auto.
