doesn't need t orun all the time, just needs to be "charged" before you need the torque,
Hmmm. Still doesn't do it for me I'm afraid.
Nothing stratospheric. 7.5 ft-lb should do the trick.

at what speed?
What sort of speed? This is a motor that was considered for the vent project. It gets you about 10 ft-lbs at 14 rpm. Gear reduction. Seems to hold up to everything we throw at it, but the output shaft has its limits.
That's pretty much what I'm looking for, TBH. It'll be reduced by a worm and nut arrangement anyway.
See my follow up to Rick C. Don't over think this! I'm just fishing for general and vague ideas at this stage.
Sorry, forgot to add the link.
It's all about speed. You can get any torque you want if you gear it down enough, but the speed will be slow, potentially glacial.
Thanks, Rick. THat's exactly the kind of thing I'm looking for - if I can find a model with the right amount of power. Good link!

And here
Marinov was a bit of a nutter with all sorts of free energy type claims, but his ball-bearing motor does work in that it rotates, albeit with very poor efficiency. It would take an imagination far greater than mine to envisage a sensible use for it.
I remember this being discussed in 'Wireless World' decades ago with various theories to do with magnetics etc, when it was obvious that it was really just a load of expanding balls.

it'll turn, but it won't be self starting and will ruin the bearings
Ceramic bearings can solve the problem. Scott Manley describes the solution:

Trouble with ceramics is they're not very good conductors, though. ;-)
