Also better efficency. If you’re throwing 10% of your output power just heating up a regular motor, then you grt a 10% boost using a superconducting motor. Or something like that.
I’m not actually sure, but I do know that there will be applications for this tech that will change everything. If it can be replicated and mass produced cheaply enough
While a lot of the time the applications of a technology precede it’s discovery, it’s certainly not ultra rare for the discovery to prompt the applications, because nobody ever gave much thought to ‘what can we do with X’.
Hah yeah that reminds me of the IBM CEO in 1943 saying “there’s a world demand for maybe 5 computers” because he couldn’t fathom what could be done with them. it was a pretty great article overall, discussing how the same was true for solar … nobody could imagine it powering the world just 20 years ago.
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?
Well we already can do directional sound, perhaps we can find a way to do focused directional magnetic fields, and then lift things into space without using cables? Obviously, I know it’s entirely different mechanisms. Even using this to make electric motors way more powerful or something could be an application.
When it comes to global warming, I could see using them to bolster the natural field of the earth to stop more cosmic particles getting to the planet, but how could you change the orbit with magnetism?
I dunno. I’m just an overly tired & poorly educated idiot who’s watched too much sci-fi. I really should be asleep, but my natural inclination has always been to fight it until I inevitably lose (sometimes the battles are incredibly intense and drawn out). I know one day it’ll be different, tho - one day I won’t wake up and be forced to admit defeat.
Now I am curious: What kinda things can be done if we can make magnets magnitudes stronger than we currently have that can not already be done?
Would be great for magnet fishing
Find MH370
Unfortunately, Boeing 777s are made of aluminum. Non-ferrous.
At these field strengths you can probably wiggle the magnet and pull up the plane via eddie currents.
Cheaper, more powerful, and efficient electric motors and generators.
what does “more powerful” mean in this context? higher efficiency? or higher max torque?
More torque per weight of motor, or more power generated per torque applied to it.
i see so just more lightweight motors/generators then.
which makes sense considering that magnets are the functional part of the device and everything else is just there to provide mechanical stability.
Also better efficency. If you’re throwing 10% of your output power just heating up a regular motor, then you grt a 10% boost using a superconducting motor. Or something like that.

“a solution in search of a problem” does remind me of cryptocurrency a lot
The difference is, we already use magnets everywhere.
While a lot of the time the applications of a technology precede it’s discovery, it’s certainly not ultra rare for the discovery to prompt the applications, because nobody ever gave much thought to ‘what can we do with X’.

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

directed magnets are physically impossible

Change the moon’s orbit, or even the Earth’s orbit around the sun? Sure would be an interesting method of dealing with global warming…
With magnets? How would that work?
