Magnetic hose (piping mag fields)
« on: 07/01/2014 02:00 AM »
Interesting work on long distance transfer of magnetic fields, AKA a magnetic hose.

So, I guess this would imply some interesting shapes/concepts for artificial magnetic fields. Applicable to radiation shielding, maybe magnetoshell aerobraking?

Don't know could be useful for building a uni-directional field in front of the spacecraft while utilizing a shadow shield effect for the rear of the craft. This might be more efficient and less mass exorbitant than building an omnidirectional field around the entire ship. Not sure about the effectiveness for magneto-breaking which would require alternating fields and some sort of onboard plasma to act as a working fluid to work against and absorb the atmosphere into the "drag plume" of plasma.

Might be particularly useful for feeding particulate fuels for nuclear light bulbs, dusty plasma FFRE's, MHD turbines etc.

How could magnetic hoses improve those ideas?

Sometimes I just flat out don't get it.

Could still be useful to protect your astronauts from radiation, just surround your crew habitat with magnetic hoses and use the electromagnetic hose to push liquid hydrogen or some other MHD fluid through the hoses.
