Guest NoSoulX Posted March 28, 2004 Share Posted March 28, 2004 Could it be possible to use Earths magnetic field and "anti-gravity" to create a new type of travelling? Link to comment Share on other sites More sharing options...
YT2095 Posted March 28, 2004 Share Posted March 28, 2004 if you could generate or manufacture an "Anti-Gravity" ANYTHING, then the answer would be a resounding YES, however, until such time, the answer IS invariably NO as the AG part has yet to be fullfiled Link to comment Share on other sites More sharing options...
Guest NoSoulX Posted March 29, 2004 Share Posted March 29, 2004 But isn't it true that magnetic waves has a frequency or a wave? Every energy has a counter-energy. Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted March 29, 2004 Share Posted March 29, 2004 I believe that is "every matter has counter matter." Link to comment Share on other sites More sharing options...
swansont Posted April 2, 2004 Share Posted April 2, 2004 Note that magnetic forces do no work (the force is perpendicular to velocity), and so cannot be directly used to change the kinetic energy of an object. If you want to use antigravity, you'll have to discover it first. And it had better not violate the laws of thermodynamics! (i.e. you can't turn it on and off) Link to comment Share on other sites More sharing options...

ski_power Posted April 3, 2004 Share Posted April 3, 2004 Violate which law of thermodynamics? Link to comment Share on other sites More sharing options...
swansont Posted April 3, 2004 Share Posted April 3, 2004 Violate which law of thermodynamics? Any of them. If you can switch off an antigravity device, it is conceivable you could make a perpetual motion machine: Turn the machine on. Raise a mass. Turn the machine off. Let the mass fall and do work (e.g. turn a turbine) If it took less energy to raise the mass than the work you extracted, you have perpetual motion. So if such a device exists, it must consume at least as much energy as you save in lifting the mass. It can't be a static device that can be used to e.g. shield half of a ferris wheel, because that's perpetual motion, too. Once you start being able to create energy you coud also decrease entropy, so it really doesn't matter which laws of thermo you discuss; you'd be violating them.

ski_power Posted April 3, 2004 Share Posted April 3, 2004 Ok got your first part, But I lost track here "It can't be a static device that can be used to e.g. shield half of a ferris wheel, because that's perpetual motion, too." Could you elaborate. Link to comment Share on other sites More sharing options...
swansont Posted April 3, 2004 Share Posted April 3, 2004 Ok got your first part' date=' But I lost track here "It can't be a static device that can be used to e.g. shield half of a ferris wheel, because that's perpetual motion, too." Could you elaborate.[/quote'] Put your static device, i.e. a "gravity shield," under one side of a large wheel, oriented like a ferris wheel. The unshielded side is now heavier than the unshielded side, so there is a perpetual torque on the wheel. Hook it up to a generator and you have free energy, violating the laws of thermodynamics. So we have reasonable confidence such a material/device doesn't exist, unless the shield uses more energy than the wheel can generate. 1 Link to comment Share on other sites More sharing options...
