@yogthos@goatsarah Thing is: This idea is not new. People have thought about it for a long time. And in the end they all came to the same conclusion: it isn’t worth it.
Thing is that the west stopped making any ambitious engineering projects. The idea isn’t new, but the will to put these kinds of things in practice doesn’t exist outside of China.
@yogthos Physics is the same all over the world. Your goal is to reach orbital velocity, otherwise you don’t stay in the orbit. You cannot achieve this on the ground level, since the air resistance would melt your device. Also the drag would slow the system down massively. This means that you would had to carry fuel with you, to be able to accelerate, once you reached the upper atmospheres.
Also the article claims that people should be carried with that device as well. This limits the acceleration to around 4g.
Physics states that this type of travel is perfectly possible. The question is whether people want to invest into making this sort of tech or not. I’m familiar with the arguments for and against this tech already. What I’m trying to explain to you is that serious people are working on this project, and it’s absurd to assume that they don’t understand basic things you learned from a short youtube video.
@yogthos I don’t need that video for that. I’m interested in that topic for many years, means that I know enough physics to understand the problems behind that. I’m able to use the appropriate formulas for stuff like acceleration. Also I know how to perform proper research. And with this I don’t mean “Youtube”.
@yogthos I’m a space nerd, so I’m always happy to see advancements in this area. I’m no “the west is the best” guy. I’m also a fan of the Indian space program. They achieve great stuff with an astonishing low budget. And I really hope that they will launch people into space in a not so distant future.
Also I think that it is a real shame, that there is this aggressive competition in space. I would love to see all the nations cooperate in a common space program, like it had already been done, when the ISS had been built.
China is launching a lot of rockets into space. They only should stop their launches from Jiuquan, Xichang or Taiyuan, since from there they have to drop their first stages onto land in areas where people live.

I recommend to watch the following video, where someone calculated all the values: https://www.youtube.com/watch?v=hQCTTvkh7gw

Again, are you suggesting that people working on this stuff lack the understanding that you have, and aren’t able to understand these problems?
@yogthos Well, this whole article sounds like a lot of propaganda without any real facts to me.
I guess we’ll see won’t we.

It smells like tech bro nonsense, doesn’t it?
Save fuel is it? Ok, put it on a train. Water in the way? Put it on a boat. They’re super efficient.
@goatsarah BTW: This sounds like a super sized “Spinlaunch” in my ears - which also has got a lot of technical difficulties.
@heluecht Yeah, without the whole centrifuge thing.
I think, reading between the lines, someone is daydreaming about some pointless nonsense and a journalist added 2 and 2 and came up with 10000
