It uses an air cushion to reduce friction, it uses linear induction motors to accelerate trains along a route, most of the time it will cost. That means the fixed costs of the whole thing are low. The cars are pretty simple and low cost. The accelerators are also simple and make up a tiny fraction of the length of a track. Most of the track is just a partially evacuated tunnel, which is cheaper to build than a maglev track.
- tbabb 11y ago> It's not maglev Oh wow, this is too much. From the article: > "The MIT pod has magnet skis that lift it during high-speed cruising" So, in your own words, "For fuck's sake, can people at least read the article before commenting on it?" The was the whole reason I brought it up. The original design called for air bearings; the MIT team did something apparently far more expensive. This is concerning.
- Already__Taken 11y agoAir bearings require a fairly tight tolerance as to the design of the tube for the entire run no? So I don't think it's a given magnets could be more costly if it means you use more expensive track materials but not a high precision construction. Any with air bearings or magnets both being a passive track on-going costs might favor the one geological events disrupt less.
- tedsanders 11y agoPlease be kinder to others. Although the Hyperloop concept uses an air cushion for levitation, the winning pod from MIT was indeed levitated by magnets: http://news.mit.edu/2016/mit-students-win-first-round-spacex-hyperloop-contest-0201 http://news.mit.edu/2016/mit-students-win-first-round-spacex...
