Good question Peter,
A possible answer begins on page 7 of:

The lateral forces on capacitor plates is due to fringe fields.
The Casimir force is highly non-linear, so fringe forces differ
from electrostatic forces, and this difference leads to a means to
extract zero point energy.
Yes but highly non-linear means very difficult to calculate, bvut
doesnt necessarily mean the it is a nonconservative force.
Of course. The ordinary plate separation is a 1/r^4 force, but it is
symmetric; it takes the same amount of energy to separate plates
separated by r as gained from moving to r separation. However, the
force at plate edges, as I proved, is highly dependent on edge
geometry, and is not conservative there.
Casimir force is heavily researched nowadays, because it is the
strongest force at nanometer distances and therefore a big problem
for nanomachines. This doesnt look like a nonconservative force.
The other point is, that there are experiments to measure the
force, but these dont give 100% proof, so it is unproven.
There are theories that deny vacuum energy and derive the casimir
force from other atomic forces.
It was never measured between parallel plates, because this is
technically too difficult. For the experimental proof they used a
gold plate and a gold sphere and they needed 1/2 year until they
had removed all dust and could measure it.
So it is only indirectly proven, because the results from this
measurement had to be extrapolated.
Also, Casimir force was -to my knowledge- never measured near zero
degrees Kelvin, which would be necessary for a proof.
Here is an alternative theory that explains the casimir force from
electrostatics:
http://www.esdjournal.com/techpapr/prevens/casimir/casimir.htm
The author says, the force doesnt exist at absolute zero.
I am unable to go deep into all this (Or I might be able, but dont
see why it would be rewarding for me), so which of all this
theories should I believe? I dont know ;-)
Best,
Peter
If you want to look for zero point field rewards, the place to do so
is in the nucleus. MEMS sizes produce energies trivial in comparison.
