Both SpinLaunch and Solar Roadways are pure farce.

Here is how to think about them: It doesn't matter how open your mind is, you will not fly by believing in your idea and working hard and never giving up developing strength and technique to jump higher.

Even though these things are all true: Everything that ever worked started out not working. You can fly a little bit by just jumping. You can even demonstrate progress by jumping harder.
