Thats pretty awesome! I can see this being implemented for a lot of things but first thing that popped in my mine was trains with no energy lossed . Wonder how strong of a magnetic hold those flux tubes have. How much force before they can't hold the disc in place.
Air resistance = friction
so there will be energy loss, but a lot less of it.
my bad no dry friction then
That is ultra awesome. Think of the possibilities!! For evil!!
No air = No air resistance ∴ No friction whatsoever
Hmm... That would imply no energy loss though, which would be perpetual...
My highly trained senses are sensing Flawed Logic. (Yes, proper noun)
There is air resistance, just no friction.
Air resistance causes drag, which is a form of friction. Anyways if this is encased in a vacuum though then voila no more air resistance and no more friction.
Dude it would be cool if an entire platform was made like that, and you had shoes which allows you to run in the air
God I love this. I saw this a while ago but I love Physics and all that jazz. IT'S MY FAVORITE.
I prefer this:
lolololololololl or get a plastic bag, put a potted plant into it, put it over your head and breath under water.
This is the reason why no large-scale project using this principle is being utilized (to my knowledge). That little puck the demonstrator was using was made of a superconductive disc immersed in something like dry ice (still wondered why the demonstrator touched it so much with his bare hands) and couldn't have weighed more than a few ounces (oz.) It looked like it could hold its own weight, but only barely so.
I'm not so sure if this demonstrates to me as much on mechanical potentials than on quantum ordering for superconductors. Applying this to mechanical applications may be misleading, as the forces here are microscale and do not become macroscale by means of simple up-sizing.
Furthermore, the costs on making all your "levitation" pads super-cooled (below -100 C) and the power required to keep them that cool would surely outweigh more conventional methods of transportation, but still a proof of concept would be cool to see.
It is liquid nitrogen. I could see trains and rides being built from this, maybe even vehicles and elevators.
Sure, Druid, but what do you think it'd cost, and who'd pay for it?
ya reading up on it they say its no where practical yet, one of the reasons is the cost and having to keep it cooled to -300. Its a cool process and who knows maybe in another 100 years might have applications , for now though they still have cool mag trains you can ride on.
I can see bumper cars made with this.
so I'm guessing you never heard of maglev trains
Um I think china stole your plans
It would suck if that rope came undone.
think you should read the entire thread before making smart aleck comments
Opps I missed that... not only before I posted but even after you replied, how embarrassing. :blush:
