But does it scale? In the volume needed to equip the trains and tracks with it? Isn't it brittle? Doesn't it need so called rare earths, which are already in much demand for all sorts of electrification in all sectors due to decarbonization?
- sudosysgen 5y agoIt does scale amazingly, and it is much cheaper than existing superconductors. It does require rare earths, but China has the capacity to scale up production tremendously and supply is not really threatened as of now. YCBO is indeed brittle, but that's not a huge issue for maglev. It's pretty much superior in every way to existing materials, from supply to scale. The biggest issue with YBCO is the low critical current, but actually the higher the speed of the train the lesser the required current.
