@yogthos @gomp It’s the capitalist textbook example, to conquer a market by undercutting prices and to crush competition in that market that cannot compete - and to later increase prices when there is no more competition. You can see this all over the world, not only with China and EVs, but also for example with Uber and the taxi business or Europe with their food exports to poorer countries outside the EU.
@yogthos @geneva_convenience These tariff rates are calculated on a per manufacturer basis based on the subsidiaries that these manufacturers receive from their country. So it just restores the competition.
@schizoidman AliExpress already has got 2TB SD cards for 5 dollars, I guess soon you will be able to buy 4 TB from there for the same price as well 😁
(Never ever buy them from there!)
@yogthos And then the upper stage blew up, creating a debris field of more than 700 objects that now threatens satellites in the same orbit:

China has a really bad track record with their stages. They have launch sites where they drop the first stages on land - sometimes hitting or almost hitting villages (which is really bad as many of these stages use toxic propellants). Their upper stages re-enter the atmosphere in an uncontrolled way (most other rocket launchers do this in a controlled way and let them re-enter at “Point Nemo”).
@davel @merde Europe has got several fusion test plants: euro-fusion.org/
@IllNess @schizoidman I’m looking forward to alternate keyboards. When I tested a Framework device, I had the impression that the keyboard had been a linear one. I made the experience, that I need a tactile keyboard.
@Hirom With “offsite” I mean either a different cloud provider or own hardware (if you hold your regular data at some cloud provider, like in this case).
@Moonrise2473 Regardless of one thinks about “cloud” solutions, this is a good example, why you always should have an offsite backup.
@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 The link sadly doesn’t work.
@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.
I recommend to watch the following video, where someone calculated all the values: youtube.com/watch?v=hQCTTvkh7g…
@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.
@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.
@yogthos Sadly the article is behind a paywall, so I have to make some educated guesses. This idea has got multiple problems. First thing is that especially when you want to transport people (like said in the article), the g-load is really limited. This means that your rail gun would had to be incredibly long to speed up the plane to a significant speed. Remember that you need to travel at 25,000 km/h to stay in orbit.
But even when you sped up to such a speed, you would experience a ton of drag because of the air resistance. It is only feasible to really speed up in higher regions (> 70-80km). So you would need some kind of first stage that had to carry some kind of a second stage to that region, so that it could accelerate from there. But this is exactly the concept that is used by rockets like the Falcon9/Falcon Heavy or Rocket Labs Electron, who all perform a stage separation in that region and perform a RTLS or controlled splash down to recover the first stage.
Also you would had only a single possible orbit here. But in reality there are a bunch of different interesting orbits out there.
Then just think about the costs. Just calculate how much launches with systems like the F9 or the upcoming Neutron you would have to perform, to even reach the break even point.
@geneva_convenience It’s exactly the same that also happened several years ago between the US and the EU concerning civil planes. Here Boeing and Airbus compete against each other - and the US had the assumption, that the EU subsidized Airbus so that Boeing couldn’t compete. Because of that the US thought about tariffs that would have countered this.
