>>1928179>You'd pressurize the cabins.That would only make sense if you continue to stay in a pressurized environment the entire time you visit. You can't just take a pressurized funicular or cable car up thousands of meters above sea level, depressurize it and jump out to sight see or you'd have A LOT of sick and/or dead people. Worse, they wouldn't have any immediate medical care so if you get some fat American with COPD that starts gasping for air, the best you could do is throw them off the mountain and put them out of their misery ASAP. Plus the summit isn't exactly big...you can only fit at best half a dozen people on the top.
Ignoring the fact it's a ridiculous idea to build a funicular or cable car to the top of the highest mountain on the entire planet, the vast majority of people on Earth would not be able to handle the environment. Let's pretend that the summit isn't frigid cold, even if you or most others got to the top you'd probably have an extreme panic attack and cause a separate catastrophe up there. The altitude is just one challenge. Mount Washington in New Hampshire, USA is something like 1/5th the height of Everest at a mere 1917 meters (6288 feet) and has claimed more than half the lives that Everest has because although it's so short, the extreme wind and cold can swoop in totally unannounced and kill you.
