If you bother reading the article you’ll see that the motivation here is to save fuel. It’s a lot cheaper to use an electromagnetic launcher to launch the plane.
@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@goatsarah You would had to enter hypersonic regime at ground level to even have got the possibility to reach the edge of space. Just imagine the sonic boom from that … Also think about the thermal protection that would be needed for your device to withstand the air friction.

I love how you think you know more about the subject than the actual engineers building this stuff. 😂

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

@goatsarah BTW: This sounds like a super sized “Spinlaunch” in my ears - which also has got a lot of technical difficulties.

Again, I’m sure actual engineers designing this stuff have in fact thought about these things.
