well, yeah, that is pritty cool..
however, i belive it will only see very limited use (at least in the next 15+ years, imho).
why?
because even small weapons (like AR with FMJ bullets) can punsh through quite some protection.
e.g. the interceptor (and as i know all other FMJ-proof armor) consist of ceramic plates that will shatter after a hit.
(thats the principle, to break the bullet and to suck up the kinetic energy by breaking the protection plate).
you may live after a hit, but several hits will shatter it completely
(metal/composite protection like on vehicles needs to be very thick to work at all....)
-> a powerarmor with this kind of protection getting hit by some bursts/anti-tank rifle will surely be in trouble..
(perhaps not not 100% out of action, but ... )
i seriously doubt that it is possible to put enough "vehicle" armor + battery power on it to be of combat value.
as a working unit (-> aliens II) however, it may be a real breakthrough!
