  • 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.








  • I recently bought a Boox Palma, which is a phone-size Android device with a real E-Ink display.

    It’s not a phone (WiFi/Bluetooth only, no mobile radio), and with 4-bit greyscale it’s definitely an adjustment to use with a lot of apps (it has per-app DPI & contrast controls to help), but they’ve done a lot of work on the refresh rate to make it feel responsive.

    It even has midrange-phone specs (SD 6xx series CPU, 6GB RAM, 4Ah battery), with full Google Play, so it’s a quite usable Android device overall. Like most modern E-Ink devices, has a CCT warm-to-cool frontlight, so great for night-time use.

    Now would I want to use it as my only, everyday device (if it was a phone too)? Probably not. Could I? Almost certainly.

    Colour E-Ink is still quite limited (in contrast, and resolution), but I expect the patents on that are quite a bit newer and we won’t be seeing so much movement in that area so soon.

    Plays out in small tech companies too, albeit in a slightly different way.

    Got that carrot dangled in front of me at a past job. Company was past start-up phase; self-supporting and doing ok, but not outrageously well. Promises of riches should the company be “noticed” and bought for an outrageous amount.

    Of course none of that accounted for the CEO (founder and 85% shareholder) being an absolute crazy person, who would change the development roadmap into making a vastly different product than the one we (the techies) believed in, TURN DOWN THE OUTRAGEOUS SUM BECAUSE HE THOUGHT HE COULD GET A BETTER OFFER, basically run the company into the ground, and wind up selling it for a pittance (which would have made the employees’ share a pittance of a pittance).

    I mean most of us had already left by that point, but finding out around 4 years after that he’d turned down about $150M and wound up selling out for $3M, that stung a little.



  • 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.
