Shanghai to San Francisco in Under Two Hours?
- JoeAltmaier 12y agoI think they have it wrong. Super cavitation doesn't have a 'bubble of air' around the vessel. It has a vacuum. And steering is not the unsolved problem they present. Just poke vanes out into the water enclosing the cavity, like the Russian supercavitating torpedoes do.
- theandrewbailey 12y agoI'm not a nautical or aeronautical engineer, but wouldn't a sub-orbital spaceplane be faster and/or more practical? I'd also be concerned about the likeliness of running into things underwater, and not being able to see well.
- kazinator 12y agoNo, cavitation does not mean "bubble of air". It means "bubble of vacuum". Well, not really, of course, but rather "a bubble of the vapor of the given liquid, at the liquid's vapor pressure (whatever that is at the given temperature)" which is the closest thing you get to a vacuum when you forcefully move some liquid around so vigorously that it separates from your apparatus.
