Quantum Levitation Demonstration! Superconducting Sapphire Crystal Allows for Stabilized Levitation Over Magnetic Field

New quantum levitator attracting interest at North Museum

...The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of foam is placed on top and held in place with household plastic wrap. The disc is then dipped into a brew of liquid nitrogen (temperature: minus-300 degrees Fahrenheit).

This creates a superconductor — an object that conducts electricity without resistance and no energy loss.

When placed atop a powerful magnet, the disc appears to float or be trapped by the magnetic field. The combination of magnetism and superconductivity create the levitation.

Quantum levitation is nothing new — scientists have been studying it for decades, Ringlein said. But the materials used in the museum's levitator take the technology several steps further.

The disc doesn't have to remain flat but can be tilted and will maintain the same angle as long as it's above the magnet. You can even flip the magnet over without the disc falling off.

Ringlein said the sapphire crystal coating is the key to the device's stability — and its high cost. The two discs included with the levitator represent about two-thirds of the device's total cost, he said.

The magnets also are expensive and powerful enough to wreak havoc on credit cards and cell phones if you stand too close to them, said Amanda Eckinger, the North Museum's marketing and membership coordinator...

Very cool, to use double

Very cool, to use double speak.

Of course the assertion in this article that there's no energy loss is absurd. It takes quite a bit of energy to get a material to -300. It takes quite a bit to maintain it at that temperature. Although we throw around the term superconductor, it's doesn't exist, be definition, outside extreme temperature manipulation, which requires significant energy inputs -- at least here on Earth.

"significant energy inputs"

For now -- but once we discover room temperature superconductors (which may require one or more additional supernovas to get to those higher elements which might allow it), then the energy inputs are less.

Of course, several supernova as a requirement to one's machine does seem to be a significant initial energy requirement.

But if it gets us to a state where we can generate energy essentially freely, then let's get out of the way and trigger one! :)

I love you. I'm sorry. Please forgive me. Thank you.

When I first saw this a couple years ago, it blew my mind

still blows my mind. The magnetic "locking" is amazing!
