-RC- Posted August 28, 2014 could you just put in like sonar buoys or something along the route to sense when it needed to slow down to avoid collisions? Share this post Link to post Share on other sites
wert Posted August 28, 2014 Probably just behave like a blown up party balloon when you let it go... Steering it will b3 an issue unless its run along a track or cable at those speeds. 2 Share this post Link to post Share on other sites
kapitän kamasutra Posted August 28, 2014 Clever idea with the gas bubble. I imagine it leaves a tunnel of death as it plows through the sea, boiling water and imploding fish... 5 Share this post Link to post Share on other sites
Dreamwalker. Posted August 28, 2014 (edited) I guess it would be like modern fighter jets...they can only be flown by computers....constant minute adjustments....I like the concept...a bit like a warp bubble for space ships....I'm surprised they haven't designed a vacuum bubble for earth launching space craft ...create a vacuum around a ship & it would pop up from earth to space like a cork in water........... http://grupocaos2007.brinkster.net/supercav2/supercav2.htm I would have thought the bubble would be nano thick?... www.youtube.com/watch?feature=player_detailpage&v=oL8fcygHL1Y Edited August 30, 2014 by Dreamwalker.

ThunderIdeal Posted September 27, 2014 (edited) if you could make such a bubble sufficiently strong then space elevator would be on the cards as well. ^ if this supercavitation technology ever sees light it will be in military applications for sure. at first anyway. ng said the group, whose research is ongoing, is hardly alone in exploring the possibilities of such modes of travel. He said many scientists worldwide are working on similar projects, but "the latest progress remains unclear because they are regarded as military secrets."Read more at: http://phys.org/news/2014-08-china-team-tech-supercavitation.html#jCp Cheng said the group, whose research is ongoing, is hardly alone in exploring the possibilities of such modes of travel.

ace1928 Posted September 30, 2014 This stuff has been going on for a long time. They trialed similar tech on some aircraft ages ago to effectively use sound waves to create pockets in front of a jet that were "vacuums". It wasn't super effective in the air.In the water it sounds pretty awesome. It would take a god damn lot of energy to move that much water though>As for steering it would essentially be the same as normal. And as dreamwalker said computers would/will do most of the guiding.You wouldnt need tracks or anything and it might even be possible to use radio waves or ELF waves instead of normal sound waves to see what is in front, below, behind, above and to the sides of the submarine at the speed of light (roughly).Curious to see how it goes.As for the vacuum bubble for ground to space the material to contain a sufficiently strong vacuum would offset the buoyancy of the craft itself. It has legitimately been looked into a long time ago as an alternative to lifting gases.Perhaps some of the new advanced nano carbon compounds (like nanotubes, buckyballs, graphene etc) or something along the lines would be able to be sufficiently strong AND light for a large "balloon" to lift cargo into space.Interesting times ahead 1 Share this post Link to post Share on other sites
Dreamwalker. Posted October 1, 2014 (edited) I'm guessing the vacuum space bubble would use magnetic, lasers..or combinations, in a guided wave/spiral/vortex form as containment, if the load was shifted fast enough from earth to space perhaps most of the energy could provided from an earth base....just dreaming here.

ace1928 Posted October 1, 2014 I think using magnets or lasers would be tough for making a vacuum mainly due to heat.For example if you use lasers to say heat air in a tube so much that it ionizes and then pulse a large magnetic field (or run electricity along the ionised air) to make it evacuate the "tube" the heat would be insane.If you used magnets to somehow get it up there you would have to seriously seriously worry about eddy currents and what not causing massive heat and potentially expansion of the metallic object in sync with the frequency of whatever signal you are using (if it is an alternating signal).Vacuum space bubble would be incredible. So incredible. The way i see it being feesible is some kind of super strong complex that is also very light and essentially giant "space blimps"But even these wouldn't truly exit the orbit of the earth. They would just carry your payload to a point in orbit where it is far far easier and less energy intensive to launch from.Oh the potential in the future. It is amazing 2 Share this post Link to post Share on other sites
