Is there a continued research on super-conductivity? Can we apply it to aircraft propulsion?

Question

We've known that a super-conductive material can float on a magnet, Earth is just like a very huge magnet...

Answer 1

The Earth's magnetic field however is relatively weak, especially compared to that required to suspend a 450,000lb. airplane thousands of feet in the air. Superconductive magnets generally have been used to suspend objects above another magnet only a few millimeters to a few centimeters, and that wouldn't get a plane from New York to London over the ocean.

Now Maglev trains and cars would be great.

Answer 2

The best use of magnets on aircraft would be an all electric fan that used the magnets in the fan ring where the magnets would be excited by multi-phase - in effect creating a large induction motor - in this way someone could make a hybrid aircraft where the turbines would be there to generate power & the fans were separate excited. This would be nifty because if you had a turbine failure - you could still power both fans from the remaining turbine - no ?

Answer 3

I agree with Jerry L. maybe your idea will work on Jupiter, but i doubt it will work on Earth. You could try an ion engine to propel you aircraft over the ocean too...
