Quantum levitation.

No mind games this time. Just providing fodder for geeking out.

Quantum levitation. [VIDEO]

Yeah I saw that. Some seriously cool stuff!

I thought this thread was about Modulus basses.

Science FTW!

That is awesome. A lot of implications for energy conservation as it applies to transportation and the like.

Nothing new there.

We do that to get some awe from the high school kids when they come visit.

If it's new to you, fair enough

I don't think we'll ever see it beyond that sort of scale. The materials used are simply too expensive.

Well, if we could come up with some easy to mass produce superconductors, (ones that would work at room temperature so they wouldn't need the LN2 cooling would be nice too, but not critical as LN2 isn't very expensive). Would struggle to lay any sort of rails that had a strong enough magnetic field to counter the sort of masses involved with real-world transport (not to mention the rarity and expense of ultra high strength magnets).

Meissner effect?

Computers weighed tons and tons and took up entire rooms of office buildings before too.

I'm not saying they're analogous, but the rate with which technology advances, in my mind, makes most things that are considered too expensive or too bulky a very real possibility in 20-30 years.

The real future of anything Quantum is in the field of Quantum Computing. There is some seriously amazing stuff being done in the field at the Perimeter Institute just down the road from where I am sitting right now.

It isn't just the expense. It's the rarity of such materials. As I said, I don't [i]think[/] we'll see it beyond that scale, certainly could be wrong.

This effect has been known about since about the same time as the first transistors (a few years before the first transistors were actually made IIRC).

To scale it up you either need to have massive cooled, superconducting rails or massively powerful magnets. Nothing which exists which could be used to hold up anything close to the weight of a car or train or whatnot. Not to mention mass laying of such tracks (again, enough of the raw materials just don't exist on earth).

I wouldn't say they are analogous at all sadly. The possibility of scaling down transistors was always there. Here we need to scale things up, massively.

In the next 20-30 years we'd be lucky to see a room temperature superconductor.

Quantum computing is smart. I don't know if it'll ever be seen as useful for day to day use (but it is possible it could be), but the potential for huge equation solving issues, it's beautiful!

That fact that it is self encrypting is, IMO, the best and most useful part of it. The business, banking and government applications of it are all mind-boggling.
