a British company named magnifye have created a way to make superconducting magnets that are a ten times more powerful then some of the best and about 2 million times smaller.

researchers at the university of Texas have learned how to create carbon nano tubes that can be used to create wires of various compounded, including superconductors, and they would be pliable.

a Japanese researcher has used red wine to create a superconductor at a much higher temperature using FeTe0.8S0.2 by sealing iron (Fe), tellurium (Te) and tellurium sulfide (TeS) powders into an evacuate quartz tube and heating the mixture at 600°C for 10 hours.

so within 5 years i would expect the price and size of superconductors to decease radically.
