Sir,
I really do wish and relish the talk of new technology and every conceivable possibility. But I must ask, do you believe in the existence of a greater power outside of the control of the ability of man? I am just curious for my own morality sake. Just like the nuclear bomb; technology, has not always had the best interest of the, longevity of existence, in its overall scheme. But things that came of it, medical advancement and the quality of life (matter of perspective)... Just technology always is a two-sided coin. I only ask because I am not you and don't know you, and I don't mean any disrespect or offense.
I have no formal college degrees or credits. lol. I have my high school diploma, graduated with a 65.4%, hahaha. I enlisted in the Marine corp, they offered me to be a nuclear physicist with security clearance, etc... I just could not shake the idea my country did not always have the best interest of its people in mind at all times...on a militaristic end why would I create or seek to improve that end of tech, with that thought.... at least I felt that way for a long time, the more I realize that my people care about their own...I was an infantry grunt until I was discharged... I'm 23 and I say that life can be better for everyone... not for personal gain.
That aside:

As far as superconductive material, what kind of system is used to keep them super cooled to such low Kelvin temperatures? I believe nitrogen gases or similar?
Can Magnetic levitation be achieved with liquids? the chart on the wiki page had water I think in its list of diamagnetic substances?
The tesla coil:
http://en.wikipedia.org/wiki/Tesla_coil
tesla had several different patents pertaining to this concept, receivers to draw incoming "electric energy[?]" and senders/transformers, the coil concept itself, for the most part. I was wondering if the distance between sender & receiver is made small, can the focus be brought down to a specific controlled point, rather than random uncontrolled electrical arcs as seen through its "novelty" applications? It all has to be tuned[?] when build to maintain the flow of electricity, and can be self sustained with the original power source unplugged or removed once it reaches a specific output of energy. With the materials available today, can his equations for building a coil be put on smaller scales than the bulky ones seen on youtube? hmmm, that thought just doesn't seem good enough, the voltage would be so small and only multiplied so much. But then you can put many tuned together to make up the difference, no? (I think cell phone size or smaller?)
And or a hydrogen fuel cell the size of a fanny pack or back pack?
It has to be small enough to be portable yet large enough to do the task at hand.... sometimes it feels like spinning wheels though.
Let me leave you with a "bit" to chew on;
