  Is it though? The link only discusses the theory of placing a large magnet in the Mars-Sun L1 point. It does not discuss the makings of that magnet. What's going to power it? Solar? Nuclear? So at the end of the day, I'm still left not knowing if we have the tech to be able to do this. This seems like a no-brainer of something should/needs/must be done to make humans living on Mars anything more than just a though exerciser.

    At it's simplest is a ring with power flowing through it, the power requirements would be minimal, 1 Tesla needed and a deflection of a fraction of a degree. I've seen estimates in the single digit MW range which we build solar plants on Earth for a few million each. Power generation is somewhat irrelevant, getting the material up there and maintaining it will be the real monetary challenge. Read the link at the end of the popsci article. There's a huge amount of research going into generating magnetic fields for spaceships and inhabited bases.
