- mikeyouse 11y agoThe test track is too short to get up to full speed so the compressors wouldn't provide any functionality at this scale.
- IIAOPSW 11y agoRight but then what's the point. That you can run a maglev in a tunnel?
- pinktennisballs 11y agoEvacuated tunnel. And actually it is a big deal considering the speed of travel which presents new problems. Also all designs are focused on scalability of system
- kuschku 11y agoBut then stop calling it Hyperloop, and call it the VacTrain it is. Nothing revolutionary, has existed for many decades as concept.
- bobbles 11y agoThey talk about a vacuum tube and so on but specifically the point of the hyperloop was that it WASNT a vacuum tube
- om42 11y agoI mentioned in another comment that there are a couple different designs for levitation and all of them do not need a compressor system anymore. Even the air bearings can rely on on-board tanks of compressed air (even at full scale). The compressor is too expensive to implement and would require high power which isn't feasible since it adds cost and weight to the batteries.
- InclinedPlane 11y agoThat's not how the hyperloop works. The air isn't for moving, it's for reducing friction using the air hockey table effect. The acceleration is provided by linear induction motors in accelerator sections. It's that combination which results in a high speed train at low costs.
- IIAOPSW 11y agono, the hockey table thing is a convenient (but unnecessary) side effect. Moving the air from front to back (with a pump) is needed to compensate for being in a partial vacuum rather than a true vacuum. Without the air pump you don't have a hyperloop. You just have a maglev in a tunnel. I never implied that moving the air provided the motion.
- tod222 11y ago> Right now this is just a fancy maglev. Precisely. There are no air intakes on the nosecone. None needed, since there's no air hockey suspension. I'm surprised more people didn't notice this. I was shocked when I saw the change. The Best Overall Design Award was given by SpaceX to a design that's not Hyperloop as we know it—just a maglev in a tube.
