Been a fan of this for many years. Its likely the source of my fascination with "active structures" from reading far too much about "dynamic compression members". I really thought it would be cool to build a small scale prototype before I looked at the physics more closely and realised how genuinely hard it is to build the turnaround magnets whatever else you use to bend the "mass stream" back around to the other direction. Still think its cool, but I realised its way beyond what I can possibly build myself with some ball bearings, magnets, and capacitors and electronics like the guys making coilguns use... its way more difficult than that haha.
