Yep i saw this, but to make this work, we're going to have to figure out a way maintain the low temperature requires for LN2 to stay liquid. That might be a lot of power usage, although I'm not sure how much that would be compare to the current power needed to run the trains we have.
 
Oh, hmm, not counting the LN2, which is cheaper than water, I suppose the quantum device might be very expensive. Hahaha! Yep very awesome as a toy indeed! Hmm I wonder how expensive it is to produce this whole set..
