When you make a magnetic shield around your vehicle and if you use a dipole magnet the particles of interest accelerate towards the poles.

I'm kinda buzzed and only skimmed the article, but it looks like the M2P2 from Robert Winglee, I know that shiat and it is neat, but it is a cyclotron of death.

The idea is nice but you need a BIG field, a single ship does not do that so well, since following the field lines to the magnetic source result in irradiating the crew anyhoo.

You'd rather have a swarmbot array around your ship with individual fields to take that blow.

They would have to be in nested groups and would asymmetrically address the source of solar particle events and mostly ignore GCRs.,

Aah crap, I'd tell you more, but I have to go to bed.

In a nutshell.

- inner layer of swarmbots create a directional field.

- outer layer detects incoming particle events energy levels and transmits data back to core vehicle.

- core vehicle coordinates response and monitors effectiveness.

Couldn't you just place some physical shielding around the poles of the dipole to serve as "rat traps" for the particles being funneled through the field lines? Surely that'd be lighter than wrapping the whole vehicle in shielding.

The distributed microsat network sounds cool too though.

Recent evidence from NASA's Curiosity rover mission to the Red Planet has revealed that astronauts on the round-trip would be exposed to high levels of radiation from cosmic rays and high-energy particles

Recent? Haven't we known about this for a long time?

I've decided I no longer want flying cars. The idiots around here are flat out not crashing into things when they back out of their garage in the morning.

See, what sucks about this, and most people don't consider it when watching Star Trek is they're basically the military, flying around in space in these ships.

For average nobodies down on Earth, it's business as usual.

They could be up there right now going warp speed with cloaking devices and wave motion guns, chances are I'd never see the inside of one!

People down on Earth work doing what they love in a society without any money. Seems like a better life than flying around in space until you get blown up or die on an away mission.

It is my understanding that the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) generates a similar magnetic field. I wonder if it could be harnessed for the same purpose.

I imagine the challenges and dangers of space travel would appeal to some as opposed to being trapped on a planet where your existence leaves nothing to chance, success is guaranteed or at least there are no real consequences to failure just as the actual rewards for success would be somewhat limited.  I can see how such a society would eventually stagnate and die off.

There was no end of crappy jobs in Star Trek.  It always made me wonder -- who got to decide who lived the horrible lives of drudgery and who lived the awesome lives?  This was a society with amazingly extreme poverty, the kind of which is vastly worse than anything we see in the US, on the order of the lawless areas of Somalia and you have extreme wealth.  It's an odd, odd place.

Not to get all geeky, but isn't this more akin to the Enterprise's "navigational shields" produced by the main deflector array? I mean, the Enterprise didn't have a hull that was meters thick. Hell, some of the windows looked like they weren't even there.

Yeah, I was going to say; this is more like the deflector than actual shields. At high speeds, even a stray hydrogen atom could do serious damage to a starship, and deflectors are designed to sweep these particles out of the way. They're useless for anything bigger than a few molecules across, and so they're not the sort of thing one would want to depend on in a fight. But for just getting around, they get the job done.
