WHAT IS A SUPERCONDUCTOR?

Superconductivity is a phenomenon of exactlyzero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.

100 billion flux lines

QUANTUM LOCKING

Magnetic flux lines(flux-ons) do not move and are pinned inside a Type-2 ultra-thin superconductor .

WHY QUANTUM LOCKING ?Magnetic Flux is QUANTIZED inside the

superconductor i.e. Magnetic flux enclosed in a superconductor is integral multiples of fluxons.

WHAT IS IT MADE OF ?It is made of a ceramic compound

YBa2Cu3O7-x .Tc = 93 K Cooled with liquid N2 .

MAGLEV Vs. Q.LEV

Based on the quantum locking principle.

Diamagnetic property of superconductors are used.

Only occurs in Type-2 superconductors.

High stability . Multiple vehicles on the same track at same time is possible.

Can lift very high loads. Electromagnets required

on the rail only.

This is based on the repulsive nature of the magnetic fields.

Conductive property of the superconductors are used(Electro-magnets).

Type-1 as well as Type-2 superconductors may be used.

Low stability.

Lift lesser loads in comparison.

Electromagnets required on both rails and the train as well.

FUTURE?

1. Gravity loophole

As superconductor locks a particle above and below its surface, it can be used anywhere to create an environment without gravity.

2. Frictionless Bearings

A lot of energy is wasted in bearing friction even though the contact area is too small .It is because of the perpendicular force. But in case of quantum levitation the bearing remains suspended in mid air.

FUTURE OF QUANTUM LEVITATION

3. Q.lev Trains

Quantum levitating trains are far more stable and practical . They require lesser magnetic field to operate and also can carry heavy loads in comparison.

Future of Quantum levitation

4. Lossless Electrical Machines

Generally Electrical machines faces a lot of losses like Hysterisis loss, Eddy current loss, Copper loss , Friction & Windage losses .With the help of HTS power cables copper losses have already been minimized. But this Q.lev will help us in minimizing the windage and friction losses. This will also help in minimizing the leakage flux to zero.
