  • EV owner here. 50 miles is not practical, beacuse then I need another for the other 2% of trips that are longer than that. This also ignores detours or traffic jams, when google will try to reroute me over a longer, but faster route. Plus, the “50 miles” readout you get is always just an estimate and the real range depends on temperature, driving speed, start-stops and how much elevation you need to cover. Some 30km trips here cost me 50+ EV km because its all uphill in one direction. I usually add 30km to my trip as required charge, because when the battery reaches 25km the car starts to complain with a nervously blinking battery readout and a “Charge now!” message on the dashboard.

    “But then you just charge during the trip!” - Well this only work if i go somewhere where i know where to find RELIABLE chargers. I am well aware that there are good apps that show me charging locations, but getting a charging spot I can actually use is a different story:

    • charging station can be used by someone else, or there is queue and each car will most likely charge for 30+ mins. Of course, sometimes some inconsiderate pricks will hog a spot untill their car is fully charged, even if it takes his frikkin tesla 2h
    • charging stations close for repairs, sometimes for weeks
    • some charging stations need an account or RFID-tag before you can use their (but not other) charging network
    • other charging stations require you to bring your own cable
    • some charging stations dont have the connector you need for your car
    • some stations on the map are bogus, for example that one at my local volvo dealership that only exists to charge the showroom and customer cars, but is not accessible to the public.

    Not saying EVs are bad, but the charging infrastructure still needs some work to be reliable and accessible. Petrol stations always have some large, obnoxious signs on the side of the road that you cant miss; Charging stations are sometimes just a tiny grey box on a wall and a 5-space parking lot, or behind a building and you never notice it when driving by.




  • You underestimate how affordable or accessible a computer was in the eastern block. For reference, a color tv that is “mass produced” and didn’t need much expensive high tech parts would cost as much as you would earn in one year - if you manage to find one in a shop.

    For a computer you needed to find keyboard, drive, monitor, software and the computer itself which would be at least equally expensive to a color tv.

    All the chips had to be manufactured locally in the eastern block, because there was an embargo on western computer tech. RAM alone was 10x more expensive because the manufacturing process was very inefficient.















  • While i would love to travel by airship, I dont think there would be a commercial success in airship passenger travel in the near future:

    • travel times of multiple days means you probably need 2-3x the crew, compared with a plane on a 8h flight
    • this also means a plane that is 4x as fast can make the same trip 4x more often, bringing in more money for the airline in the same amount of time
    • you probably can’t land on existing airports, because an airship the size of a large building would be crawling accross your airspace blocking all flight traffic, or shaken by the turbulences behind a large jet powered airliner
    • new technology without any existing infrastructure is much more expensive than building on top of existing things
    • tickets would be much more expensive than a commercial plane because of the reasons above, the lower passenger capacity and the fact that you have to carry more supplies (water + food for days multiplied by people on board) for a longer trip. Each passenger with cabin and supplies was calculated as 300kg weight on a transatlantic flight on the hindenburg
    • Hindenburg could not fly in a direct straight line, because it travels at a height of only 400-600m. This means you had to go around high mountain ranges, because people and the combustion engines need oxygen which you dont have much above 4000m. However i dont know if this is still a problem with modern pressurized cabins, or if there is another limitation from the lifting gas…
