Palm-sized magnet reaches 42 tesla, approaching the strength of the world’s most powerful magnets while using a few thousand times less power and over 1,000 times smaller coil volumes (interestingengineering.com)

Contactless autonomous cranes.. space elevators.. perhaps fusion or fabrication advancements.

space elevators

i remember doing a bit of math around space elevators a year ago and figuring out that if you make a cable hang from outer space to Earth, then the tensile strength is not strong enough to carry the weight of the cable itself. if you use any materials available today such as steel or carbon nanotubes. how would magnets change this?

Off subject but they found dangling a long cable into the atmosphere from low orbit or whatever they could generate a lot of electricity, the cable broke off after a while though when they tried it.
