As a Linux Uber-amateur, it feels like we’re basically able to do anything I would want to do on Linux now… the thing where Microsoft tries to not allow you to download stuff because they haven’t paid Microsoft to sign it has always annoyed me. This would be the next level of nope.
One thing that’s kept me on the fence is I like multiplayer games, and I had always heard that battle eye didn’t work on Linux, but with all the proton development and steam deck interest, perhaps this is becoming a non issue?
For reference: that sign is 5’ high.
Yeah I don’t understand the clamour. This sort of situation has happened many, many times. I remember reading about a guy dying in a cave near the Everest summit. Other climbers sat with him and shared water, comfort, but from that location, if he couldn’t move on his own, there was no way he was getting down. Also the numerous “landmark” bodies that the climbers pass right off the trail… there’s no safe way to remove them.
I think people assume that you can just carry someone out on a stretcher or arrange a helicopter—but people are literally operating on bleeding edge of oxygenation and helicopters can’t get up their for the same reasons… you aren’t going to be able to remove an incapacitated person who needs total physical support from others to move.
You could say, well it’s fucked up that people are paid to support these climbs, because they need the money, and there’s some validity to that, but in that case it’s not that different from something like deep sea welding or being in a combat unit of a military, etc.
It’s about lift generation and gravity. Planes stay aloft because of the lift generated. So plane takes off near horizontal, with engines creating thrust in a near horizontal vector. The shape of the wing, combined with the near horizontal thrust vector creates lift, which is perpendicular to the thrust vector, and is what exceeds the pull of gravity, so you climb, while also moving forward. Depending on how you angle the wing, you change that lift force/vector so you can climb, fly level or decend.
If you angle a conventional plane vertically, it will still generate “lift” but that lift will be angled perpendicular to to gravity force. In reality, the plane “stalls” before vertical—this stalling means the wind angle has gone beyond where it can generate enough lift to keep the plane level or climbing. Simply put, most aircraft engines are completely insufficient to escape gravity on their own, they’re using a mechanical advantage via wing generated lift to stay up.
Space rockets use an immense amount of force to escape the atmosphere, they’re basically using a direct vector force to cancel out and exceed gravity, as well as friction. This requires fairly mind boggling amounts of fuel (energy) to do, which is why pounds of cargo capacity are extremely limited.
A VTOL aircraft that has thrust vectoring, can aim thrust down vertically to rise off the ground vertically for a period of time, and then rotate the thrust to the rear to enter into standard lift based flight. I don’t know this exactly, but I suspect the vertical portion of the VTOL sequence is much more energy intensive than the horizontal portion.
Helicopters are neat because they generate vertical lift, but that rotor plane is also capable of behaving like a wing, allowing them to mimic some aspects of fixed wing flight. For instance, if your engine does, you can use autorotation (basically as you fall, it spins the rotors, and you get wing lift so you can “glide” in to land safely).That said, helicopters are less efficient than a fixed wing, which is why if you fly across the country you’re in a large plane, not a helicopter.
I’m sure there are scientific details I’m missing here, but that’s my layman’s understanding of why you can’t point a standard aircraft vertically and fly straight up.
There is a cooling strategy like this called “chilled beam” but has all the issues listed below by other posters; condensation management and power usage.
I’m in a similar boat. The use case where I really would use it regularly, simming, is hamstrung by two things. One, it’s so damn fiddly and laborious doing settings non stop to make it playable, and two, even if I get the settings right—I start noticing weird crap with my eyes after a couple sessions. Like you end up basically crossing your eyes all the time inside the visor, and I’ll notice fatigue/trouble focusing after using it a lot, what I would imagine it feels like to have a bad prescription or something (don’t personally have glasses).
And as you say, it’s bloody uncomfortable. Something like big screen beyond with good AR/passthrough would go a long way to fixing that I guess.
