  • If you have a recent phone, websites and PWAs are about as fast as native apps. I’m using a 2014 flagship Sony Xperia Z that came out with Android 4.4 and can barely run Android 13 — it will overheat and sytem UI (thankfully not apps) will restart if rendering stuff for too long. (The difference is staggering: basic old apps like Phyphox and static websites run indefinitely. Modern apps or JS-enabled pages like Voyager or 480p30 video for 10 minutes. Post-modern bloated crap or 720p30 video, 4 minutes. Imgur, new Reddit and 1080p video turn the phone into a hand warmer immediately and the framerate goes from 15 to <1 in 10 seconds, followed by a slew of ANRs and the battery percentage going down every 20th frame rendered. Should I have applied more heatsink compound after replacing the battery? Yes but I’d argue no app with a simple purpose and basic GUI should require 5 W to the CPU while running at half rate.)

    The 1963 Černý Důl – Kunčice nad Labem aerial ropeway is over 8 km (5 mi) long, over 30 m high in places and carries 135 tons of limestone every hour from a quarry to the nearest train station. Its 120kW 3-phase synchronous motor requires power for a few minutes at the start and end of each day when most of the 800kg-capacity trolleys are empty, and spends most of the shift generating mains electricity and acting as a speed governor. Unlike the EV, it is fully autonomous most of the way, only 5 people are required to operate it. (Loading, unloading and timed dispatching is automatic, arriving/leaving carts just need to be checked; a safety latch has to be manually dis/engaged on trolleys passing the check.) The quarry will continue operation as long as it pays off, then the ropeway will be scrapped (projected 2033). A dude illegally rode the way up on it somewhat recently. He could have fallen to his death if he pulled the latch.
