  • They’re not—as long as the PV cells are a supplementary charging solution, in addition to wall charging, to the batteries. You’ll get a bit more range out while driving, especially when the car is a lightweight low drag design and PV cells may be the only thing needed to keep the constant 90 km/h speed in a sunny day. And when not driving the cells might be enough to get the 10…20 km or so commuting range back over your 8-hour workday.

    But putting PV cells on a 3 ton electric SUV or pickup truck is stupid, it won’t do jack all due to the inherent inefficiency of such vehicles.





  • Saying that AptX is lossless since 2016 is blatantly false. And yes, just like with HDMI and USB, AptX standard naming and Qualcomm feature naming schemes are a misleading mess.

    There are 4 flavours of AptX (linked article states this as well), and only the latest supports lossless, but is available only on very few chipsets and devices so I even forget that it exists, because for all practical purposes it doesn’t.

    Denon Perl Pro, Bose earbuds and Cambridge Audio M100 are the only non-chinese earphones that I know of that support AptX lossless and the latter are not even listed by my local importer. Plus, you need a very specific (expensive) phone to use them because AptX Lossless is not available for all chipsets. Basically, Asus ROG 8 or Xiaomi Redmi K70 Pro for ones available to buy for me, and then it’s not available at every retailer, either, and the b2b wholesalers I have access to through work only list ROG Phone 8 (~1200€ retail).

    In conclusion, to make use of lossless AptX you have to jump through many hoops and spend a lot of money—700+€ phone and the 200+€ earphones. The standard is far from being, well, a standard; common and widespread. 99,9% of devices on sale and in use by people only support older AptX standards, mostly AptX HD (which is not lossless!).













  • it can’t be a bag for dry food because it won’t keep the food dry.

    What dry foods actually need to be in a watertight container and how often do you immerse your packaged dry food in water or leave it in a humid environment? Back when I hiked a lot our circle of friends packed all the dry food we took into reusable fabric bags and had no problem keeping it dry for weeks in snow and rain.

    Quite a lot of dry food is packaged in paper or carton—flour, cereal, couscous, sugar etc. For some reason (at least where I live) most dry food that are my staples like rice, pasta, buckwheat is packaged in plastic but could just as well be packaged in paper. It’s not like rice or pasta is more vulnerable to humidity than couscous or sugar (packaged in paper/carton).
