Wouldn't it be great if you could monitor these magnetic fields around the Earth and make a strong enough electromagnetic field, Producing the same magnetic pole, to create a hovercraft of sorts...The MAGNITOCRAFT! sorry, childhood invention which I finally have a chance to bring up!
A list of advantages of a vacuum zepplin over a helium or hydrogen one;
1. Content, there isn't any, and of course nothing is always readily available! so if a leak were repaired, just suck out what went in!
2. Strength, I believe a zepplin of old was made from canvas and whatnot, MUHAW EAT...
well this sure has put the physics forums into thought, I think pre-filling the space to be vacuumed with helium (just as an example) could possible help with decompressing the volume, as you might be lucky enough to avoid that nasty stage of water vapour on the walls of the chamber (read that...
Hia, I am not a student, I am a gas engineer in the UK. Had a thought and tried out some theory but didn't get very far.
Basically; if a helium balloon rises in air as it is lighter than the air it displaces, what if I could get a tube (say internal dimensions of 15mm in diameter and 1000mm...
