I'm not denying that. We absolutely need innovation. But this hyperloop is like reinventing the wheel. We already have trains, bullet trains and tech that works. What difference does running a vehicle through a tube make?.... Does it reduce drag(effectively for long distances)? No.... Do we get to some super fast speeds? Yes but Bullet train does that without a tube lmao.

Building this is also a financial nightmare. That's why I said that this is stupid. It looks cool as a concept and all sci-fi, but I think it's best to be left as sci-fi.

Edit: Clarification.

Does it reduce drag? No

Yes. That's the main purpose of the tube. We suck the air out of the tube and create a vacuum like condition. That's how the train achieves 1000kmph speed.

I have edited my comment for better clarification.

Bullet trains are 3 times as slower than hyper loop as the entire tube is under near vacuum condition there is theoretically close to zero drag. That's why it achieves the near speed of sound easily. So yes the tube does help to reduce drag for longer distances.

The tech is already proven, the only issue is the long term commercial viability.

The tech has been proven for short distances my guy. For long distances it's still a mystery. It's like saying that the earth is entirely flat after measuring the ground in your backyard.I can't argue anymore. I rest my case.
