    Tesla Cybertruck Will Have Neuralink Controls!

    Sounds more like Cybermen.

    I think the Cybertruck is going to require around at least 500Wh/mi. If it is going to get 500 miles of range, it needs a 250kWh battery pack. The chemistry doesn't matter. 250kWh is 250kWh no matter what the chemistry is.

    Tesla RV

    i was just thinking. If the cyber truck gets half the range when towing, and we expect a 250kWh battery, then that means about 1kWh/mile. If Tesla made a 14000 travel trailer., they could put in the trailer a 500kWh battery to supplement the CT. That would yield around 750 miles while towing...

    New Battery Range & Pack Architecture [Announced at Battery Day]

    Yeah, that isn't showing the benefits of the 4680. It is showing future goals. The 4680 isn't going to provide an increase in energy density.

    New Battery Range & Pack Architecture [Announced at Battery Day]

    They were vague on purpose hoping people would draw this conclusion. The 4680 doesn't provide a 54% improvement. That is technology they are working on for the future.

    Yeah, that is what I said in the original post, genius.

    New Battery Range & Pack Architecture [Announced at Battery Day]

    If it was five times the energy density, then that would give you five times the range. That would be a battery with around 1,250 Wh/kg. If that was announced, Tesla stock would be would have skyrocketed. No, the energy increased is because of the size increase. The energy density decreases...

    Dude, are you completely unfamiliar with the Tesla Semi????? They are using a battery in the 1MWh range already. It already exists.

    New Battery Range & Pack Architecture [Announced at Battery Day]

    But then why do they say the 4680 has 5X the energy when it is 5.75 larger in volume. The energy density is slightly lower than the 2170 cells. That 54% increase is likely not from the 4680 cells, but rather their goal to reach eventually.

    New Battery Range & Pack Architecture [Announced at Battery Day]

    It is just a bigger Cell. It makes it cheaper to produce. At the pack level, there might be some increase in energy density, but it isn’t 56%.

    I heard they are going to announce that Trevor Milton is coming to Tesla and is taking over as CEO. That is why he left Nikola. Trevor told me himself. ;)

    Tesla RV

    A refrigerated trailer most often has a diesel ran refrigerator. But I have looked into building a tinyhouse on wheels, and I could get that under 7,000 pounds including the trailer. Composite insulated panels are very light weight and have excellent insulation qualities. I also looked into...

    Maybe you should just get off My eyes can't roll enough at this.

    If you are talking about an ENERGY storage, you don't need to say MWh. The h is implied.

    That is the size of the battery they are already using, dude.

    What??? You do need a MW if the RV is an electric vehicle. That is how you would get a range similar gas or diesel RVs.

    Tesla RV

    My limit would be about $300K. But it would have to have enough solar to at least maintain the battery level so AC or heat isn't running the battery down. But that wouldn't be hard. A well insulted RV could easily get away with a 500W air conditioner. Oh, and it needs a composting toilet. I...

    Tesla RV

    Anyone else in love with the idea of an electric RV based on the semi? With a 1MW battery pack, it should get over 700 miles. If the aerodynamics to the rear were improved, it could get as high as 1,000 miles. Expanding solar panels could yield 10kw which if you stored 8kw, you could recharge...

    First look at Tesla’s new battery cell produced in-house with Roadrunner

    I think they will do that anyway because the new batteries won't have the power density for the cars, but will for the CT and Semi. I think the roadster will need to stay with the higher power density & energy density cells.

    Ford VP Disses Cybertruck, Calling Electric F-150 a "Real" Work Truck

    Have you never seen doubles or triples? Tractor trailers are built that way for stability, efficiency, maneuverability, and a wider CG envelope. It has nothing to do with weight. You can have all the weight on trailers wheels if you want. A pintle hitch can tow 60,000 pounds. The max capacity...
