It is a shame that other partial vacuum systems are not being developed. They seem like a useful concept, fast, less air resistance means less energy use. Surely a technology you'd want to have in a future city.
- gremlinsinc 4y agowhy does it need to be a vacuum system? Couldn't a similar device be a pod-like maglev device that floats above a magnetic track and maybe can temporarily hover albeit more slowly via some drone-like propeller on the bottom when 'off track', or for final-mile portions, could even turn into a car when not in maglev mode.
- Ekaros 4y agoOn concept level they kinda make sense. But the trade-offs are just too stupid. Basically it is equivalent of building tunnel around all of the roads. The energy investment in that sort of infrastructure is unfeasible. And then partial vacuum, that needs more infra and energy to be spend. And then the safety, on ground level open air is great, you can exit at any point to any direction. But tunnels especially small ones... That would be nightmare in best case and death trap in the worst.
