If he's looking for mega-good, Musk would do significantly better to drop a full subway network. Like Hyperloop?

- idlewords 10y agoThis is to subways like hyperloop is to high-speed rail. A stupid overelaboration of an existing, proven idea.
- mmanfrin 10y agoHyperloop is a 'stupid overelaboration of an existing, proven idea'? I was not aware we had so many proven 600mph high speed rails.
- astrodust 10y agoThey exist. The problem is getting approval to build them anywhere near residential areas is problematic. https://www.slashgear.com/japans-new-maglev-bullet-train-is-now-the-fastest-in-the-world-22380159/ https://www.slashgear.com/japans-new-maglev-bullet-train-is-... That's 600km/h. For 600mph you'd need Hyperloop to prove they can do that speed first.
- ryanwaggoner 10y agoSo...they don't exist. The fastest ones are actually 40% slower.
- astrodust 10y agoShow me a working 600mph tube train and then you'll have a case of a superior technology. Until then it's just an idea on a napkin. China is building new, high-speed maglev trains and there's many lines already open for business. Maybe one day Hyperloop will get built and will be open for passenger travel. When that day comes it's possible that surface rail may have already achieved the same speed because third or fourth generation maglev trains are in service.
- ryanwaggoner 10y agoAnything is possible, but you were making the claim they they exist, which they definitely do not. They might theoretically someday exist, but so might Hyperloop.
- astrodust 10y agoThe idea of a 600mph train running in evacuated tunnels is about as old as the idea of trains itself: http://io9.gizmodo.com/5731620/in-an-alternate-universe-theres-a-600-mph-underground-missile-train-between-nyc-and-philly http://io9.gizmodo.com/5731620/in-an-alternate-universe-ther... China is looking at building something like that: http://www.zdnet.com/article/china-developing-600-mph-airless-maglev-high-speed-train/ http://www.zdnet.com/article/china-developing-600-mph-airles... Note that it's an above-ground system because the costs of building underground are utterly ridiculous for long distances.
- alexbecker 10y agoThe high speed is the "overelaboration". High-speed rails in many countries can reach 200mph. A 600mph train may be 3x as fast, but the marginal utility is pretty low to me compared to increased cost and reduced capacity.
- idlewords 10y agoWe don't have any proven Hyperloops at any speed.

- stevep98 10y agoI bet this tunnel boring idea was inspired by the lack of an economical path for hyperloop to get to downtown LA. The hyperloop concept took a lot of heat for that.
- makomk 10y agoHyperloop was a completely infeasible design that Musk quite openly had no intention of building. It mainly seemed to exist as a tactic to attack actual planned public transport expansion in the Bay Area, which Musk compared it unfavourably to based on figures that didn't add up.
