Well the hyperloop wasn't an original idea but so is almost every invention in this world, there is no original thing anymore. 1799 might have been the year that it was conceived as an idea but it never came to the possibility of being built but Elon wants to take the theory into a real thing and that's what counts here. Also, any person who worships any celebrity or famous person like a God is pretty stupid because that would mean that you don't think critiically and only follows what the crowd does.
Well, the main problem with the hyperloop isn't that he isn't giving credit to the people who thought it up, but that it's a terrible idea that will never work.
His original idea was to move the pods with a turbine... in a vacuum.... A turbine.... IN A VACUUM
But what moves the hyperloop doesn't matter as much as the cost of keeping a giant tube under near vacuum. That requires a lot of energy and the points of failure are limitless. It's easy to create train track that can accomodate expansion and contraction as they heat up and cool down, but you can't do that with a huge tube that's under vacuum.
And then there's safety. If any section of the vacuum fails the tube becomes a giant gun that shoots every single pod into the next pod killing everyone in the system.
Despite all the problems with the idea the media is just running with it and there's massive gathering of all the people who think science is so cool but can barely think for themselves.
Thunderf00t (the man behind the channel is a successful research scientist Phil Mason) has made hours and hours of videos on the hyperloop. He tends to repeat himself a lot but he can be really entertaining.
This is a video of him running around stupid Elon Musk fans in circles when they tried to debunk his hyperloop busted videos.
Jixuan & Sebastian: BUSTED! (Part 1)
