WHAT ISASUPERCONDUCTOR?Superconductivity is a phenomenon of exactlyzero electrical resistance and expulsion of magnetic fieldsoccurring in certain materials when cooled below acharacteristic critical temperature.
100 billion flux linesQUANTUM LOCKINGMagnetic flux lines(flux-ons) do notmove and are pinned inside aType-2 ultra-thin superconductor .
WHY QUANTUM LOCKING?Magnetic Flux is QUANTIZED inside the superconductori.e. Magnetic flux enclosed in a superconductor isintegral multiples of fluxons.Discrete Magnetic lines
Coated with Gold for protectionWHAT 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 lockingprinciple. Diamagnetic property ofsuperconductors are used. Only occurs inType-2superconductors. High stability . Multiplevehicles on the same track atsame time is possible. Can lift very high loads. Electromagnets required onthe rail only. This is based on the repulsivenature of the magnetic fields. Conductive property of thesuperconductors are used(Electro-magnets). Type-1 as well asType-2superconductors may be used. Low stability. Lift lesser loads in comparison. Electromagnets required on bothrails and the train as well.Maglev (non-zero potential) Quantum levitation
APPLICATIONSGenerators TransformersPower cables Energy storage
1. Gravity loopholeAs superconductor locks a particleabove and below its surface, it canbe used anywhere to create anenvironment without gravity.2. Frictionless BearingsA lot of energy is wasted in bearingfriction even though the contactarea is too small .It is because ofthe perpendicular force. But in caseof quantum levitation the bearingremains suspended in mid air.FUTURE OF QUANTUM LEVITATION
3. Q.lev TrainsQuantum levitating trains are far morestable and practical . They require lessermagnetic field to operate and also cancarry heavy loads in comparison.Future of Quantum levitation4. Lossless Electrical MachinesGenerally Electrical machines faces a lot of losseslike Hysterisis loss, Eddy current loss, Copper loss ,Friction & Windage losses .With the help of HTSpower cables copper losses have already beenminimized. But this Q.lev will help us in minimizingthe windage and friction losses. This will also helpin minimizing the leakage flux to zero.
