Whatever happened to the Dust Sail?

OK. I found something about M2P2 in print. It said the "dust" would be
ionized helium, electrically contained inside a magnetic field
surrounding the spacecraft. How the thrust is supposed to be
transferred to the craft instead of just slinging the helium out of
the containment, I don't have any idea. And it only goes in one
direction (the solar wind direction).

Maybe more like trying to sqeeze out every bit of momentum.

Hmmm...sketchy. It sounds like trying to go faster than the wind in a
hot air balloon.
