Thanks to a invention called a Super- Conductor magnetic Levititaion is possible

For the people who don't know super-conductors are rings of special metals cooled to very low temperature's till they reach the point where their electrical resistant reachs 0. When this happens the super conductor starts to repel all magentic fields. Water creates a very small magnetic field. The frog in the video is has a lot of water present in it making it float.

This is all very good but super-conductors take a lot of power to run because of the temperature' needed for them to work. So do you think this is waste of time or the way forward.

Such research is useful, but I think room-temperature superconductors are just as far away as cold fusion. Chilled superconducting lines have been used in a practical aspect to link power grids through buried cables, so it certainly isn't a waste of time.

The only way I can think of to make a super-conductor at room temperature would be to make a material that is extremely temperature reistant so that it would be virtually cold at room temperature yet still have a vey very low resistance though I have no idea how that would be done.

In other words the way to make a room temperature superconductor is to simply find a material with no electrical resistance at room temperature...

I think you're on to something!

Well this topic is one of the 2 big problems of the moment (the other is storing hydrogen). I understand the prinicples on how a super-conductor works and what would be needed for a room-temperature based conductor but I can't think of a way of making the material needed. Also from my guessing such a material would most likely cost loads to make.
