Can we use Birkeland Currents to impart torque?

Beyond the boundaries of established science an avalanche of exotic ideas compete for our attention. Experts tell us that these ideas should not be permitted to take up the time of working scientists, and for the most part they are surely correct. But what about the gems in the rubble pile? By what ground-rules might we bring extraordinary new possibilities to light?

Can we use Birkeland Currents to impart torque?

Unread postby Shelgeyr » Mon Aug 12, 2019 5:02 pm

I've been gone and away from this forum for a LONG, LONG time - sorry about that!

I also just finished typing out a long post which, when I hit "Preview", vanished into the ether and the board asked me to log in again. I blame "Firefox". So here's a MUCH shorter, and sadly less entertaining version:

If mankind ever gets around to building a large habitat in space, would it be possible to use the million-mph Birkeland Currents which power the auroras in order to spin the habitat up to the desire speed?

I assume they're too thin and tenuous for something as crude as "perimeter sails" to be of any use, but (assuming we're talking about a wheel structure and not a "bolo-on-a-cable") would charging up the exterior ring allow the hab to function as the rotor/axle of an electric motor in order to build up the necessary angular momentum?

I hope that sometime in the (unfortunately most likely very distant) future, our species will realize the dream of building massive habitats in space - the micro-world types housing cities, farms, rivers, etc., in space. So forget how to get all that mass into the correct location for now - I'm concerned about where will the power come from in order to spin it up to speed once such a thing is built.

Your thoughts?

I am Dutch so i would make it look like a windmill, i guess the surface area has to be really large in order to do anything, most "wind" would be coming from the Sun.

The biggest problem with such habitats will be the GCR levels, so unless said habitat will also generate it's own magnetic shield like the planetary one then the radiation levels would soon be fatal.
