Are there any possibilities there?Cannot 'drain' when surrounding area is at or near sea level, tunnels or no.Erm, polder. Just requires pumping and input of energy. Naturally I will agree with you given that I live in one. This one in fact: https://en.wikipedia.org/wiki/FlevopolderAnd how many 4m tunnels does it use?

One. And it is in fact larger than 4 meters in diameter. It is however not used for drainage but for running a railway to the other side of the Veluwemeer (Lake Veluwe).But strictly looking at drainage: the Flevopolder uses several tens-of-thousands of drainage tubes (approx 4 inches in diameter) to carry away excess water into ditches. Those ditches dump their water into canals. The water from the canals is pumped out of the polder into the surrounding lakes by a number of pumping stations.

Although I quite like "Musks Mole" myself. Quote from: woods170 on 09/09/2017 04:32 pmOne. And it is in fact larger than 4 meters in diameter.

A nice example of a "fractal plumbing" system, gradually collecting water. It's also interesting from the mars settlement perspective of "making" land. I'm not sure how many other countries in the world do this.
Anyone mentioned boring mall space to attach to the transportation system? Or just to create more city space in general? Just a fanciful idea that all the bits and pieces, including pressure tight access to the hyperloop and aesthetics to avoid claustrophobia, could grow to look more and more like a mars city.

Just a fanciful idea that all the bits and pieces, including pressure tight access to the hyperloop and aesthetics to avoid claustrophobia, could grow to look more and more like a mars city.I think the similarity is there. It seems like there’s a system coming together from different proposals. Transport pods like depicted in the Boring Co video could also fit inside Hyperloop pods as depicted in the Dubai Hyperloop video or Musks original white paper that mentioned Hyperloop carrying cars. Hyperloop stations could then be entirely automated spaces underground where vehicles in the air filled tube/electric skate system enter/exit Hyperloop pods and they then enter/exit air locks. So a single passenger container travels on surface streets to final destinations (or maybe even in buildings in a Thyssen-Krupp style horizontal/vertical elevator) as well as in tunnels for longer trips or Hyperloop between cities. Direct connections to underground shopping/office space/commercial underground fits well with this. Apparently Houston had a system of underground passages with shops like this that flooded in the hurricane. It would be a lot like an underground city on Mars.
In Minnesota, the universities usually have either tunnels or skyways connecting all the major buildings. Downtowns of both Minneapolis and Saint Paul both have extensive skyway systems connecting almost all the downtown buildings. There's a light rail from the airport to the Mall of America to downtown Minneapolis. It's possible to visit Minneapolis from another country, go on roller coasters, walk among trees and sharks and the entirety of the downtown buildings and leave again without ever seeing the sky directly above except through glass.
I am assuming each hyper loop pod has a life support system? What happens in a power failure? What happens if a pod loses pressure?
Quote from: Steve D on 09/25/2017 05:33 pmI am assuming each hyper loop pod has a life support system? What happens in a power failure? What happens if a pod loses pressure?For Hyperloop, where the transport tube is normally evacuated of air, if the system stops they could flood the transport tubes with normal air and then move the transport pods along at slower speeds to the next station so they can reset the system. That would be my guess.

Only a minute or 2 before they are dead. You wont be able to pressurize a tube like that that quickly.
