    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.





  • The source code is very readable, and contains all answers in lz-in-base64-encoded JSON. It should be easy to add support for playing previous/future rounds using URL parameters and/or buttons with a userscript.

    Edit: it’s been compiled with Angular.js, and I don’t want to install the IDE to change 8 lines… So I identified the function in the minified version and altered it. When I tell my browser to replace the file with a local copy, the hack works until I load another URL. I’ll try to figure out how to keep it pointed to the hacked version (which reads the ?num= URL parameter instead of calculating number of days since the first one) but making a Redirector rule fails because of unexpected content type reported by GitHub (text/plain). I don’t want to run my own server, let’s see if I can do it another way…

    Edit: Done
