People seem to think that this train will run forever with little-to-no electricity. While it's more efficient than current maglevs, you still need energy to generate liquid nitrogen (fairly cheap), make the turns (expensive but manageable) keep the conventional magnets from losing their alignment (fairly cheap), and to replace the very large and heavy high-TC superconductors that make the train work (ridiculously expensive). The fact is that these two parts will all decay rather quickly.
Not in the sense that it's easy to obtain and maintain in a liquid state.
In some ways it's like ethanol - it is renewable in the sense that you can never really run out, but making it, transporting it, and storing it are expensive and the motors are still going to require non-renewable resources to make.
You are an idiot. Trains are already fatal to society. This is a a way better technology. There would be no pollution and trains would not be able to crash. I dont think we need them going around buildings but still a great idea. Dude, there could be a hoverboard for rea with this technologyl!!! Tell me you wouldn't want one.
