Anything electric would be dramatically improved. Electric car range, consumer devices like computers and phones would have a huge jump in efficiency, etc. You name it basically.

Having a conductor with zero resistance allows to transmit (regenerative) power from where it can be generated for free (solar in the desert) all across to where it is needed without loosing any power on this way.

In theory, the cost of getting an MRI would come way down due to not having to keep the coils crazy cold. In practice, we have capitalism, so it’ll probably go up

Everything that has lots of wired coil (motors, generators, turbines, wireless charging)

Less resistance = less energy lost in these endless wire coils.

If I am recalling an article correctly - superconductors mean zero resistance electric transfer. Currently anything using electricity loses power due to resistance when travelling - partly why a CPU gets so hot for example. By having zero resistance, far less power is lost to resistance and heat which means more power efficiency

It would take maglev from a laboratory technology to a common one. That would be an enormous boon to rail tech, especially in high density corridors.

You could be a crypto bro on a Raspberry Pi.

Hell, someone might finally max out Flight Simulator X.

Last I read, current solar panels were only about 8% efficient. That number would skyrocket…

It’s a zero resistance environment. Usually you would have to use liquid nitrogen to freeze something lime a hockey puck. There are some really cool things you can do then. Especially with magnets. Lay out a track of magnets and something thar is superconducting will hover over then. If you push it it will keep its speed unless acted upon by other forces. Now imagine we don’t need to freeze the material…
