  • Unfortunately what’s shipping today seems it would offer maybe half that.

    For the batteries that were announced this past week, a larger-than-refrigerator-sized cabinet held a capacity of around 15kWh.

    Around half the energy density by mass of Lithium batteries, and in the order of a sixth of the density by volume.

    Now if only we could come up with a system where your car could be charged while stopped at traffic lights, we might be onto a winner (:

    Considering however that the price of sodium is around 1-2% that of lithium, I expect we will see significant R&D and those numbers quickly start to improve.





  • Free for personal use, so yes-ish. That’ll certainly be a deal-breaker for some.

    Realistically, people who are using it for personal use would probably be upgrading to the next LTS shortly after it’s released (or in Ubuntu fashion, once the xxxx.yy.1 release is out). People who don’t qualify to be using it for free anyway are more likely to be the ones keeping the same version for >5 years.






  • As of USB-PD 3.1 there are now nine fixed voltages - 5, 9, 12, 15, 20, 28, 36, and 48V - and two variable-voltage modes; PPS with 3.3 - 21V in 0.02V increments, and AVS with 15 - 48V in 0.1V increments.

    Combined with a few different current limits, some of these features being optional, and then doubling down with what your cable does or doesn’t support, amazing anything gets charged at all.





  • I’ve always been lambasted for this opinion, but I feel the same way about the charging cable and charger.

    I do not want yet another 1 metre (if they’re even that, most likely 3 foot) USB-C cable that barely reaches from the charger on the floor to the bedside table - and largely precludes actually using the phone while in bed - nor particularly the included charger. So many things need to be plugged in these days that single-output chargers are also basically e-waste.

    Of course because some business genius had the idea that making the USB cable 0.9 instead of 1.8m saved them $0.06 per unit shipped, we all got lumped with those useless cables.

    Now of course there will always be people for whom it’s their first phone (or whatever situation), who do need those accessories. But all that requires is there to be a retail bundle with the now-accessory charger and cable. Preferably that bundle costs the same as the phone with them included does today and you get a token discount for the phone without them, although we all know it would never work that way :(
