Besides coolant to maintain superconductivity of the yttrium barium copper oxide ceramics on board, life-support and sanity-preserving systems (such as big video screens to distract its passengers from the fact that they re hurtling through the choking darkness),
The third differentiator is the use of high-temperature superconducting maglev, which ET3 licensee Yaoping Zhang pioneered at China s Southwest Jiaotong University.
The capsules carry the superconductor, allowing for a simple guideway. Linear motors launch the capsules to jet-aircraft speeds and beyond;
which can be metals semiconductors dielectrics and even superconductors. This material is the newest in a growing family of two-dimensional crystals says Arend van der Zande a research fellow at the Columbia Energy Frontier Research center and one of the paper's three lead authors.
Ceramics are used in a wide variety of technologies including body armor fuel cells spark plugs nuclear rods and superconductors.
