I lifted this......
"The Casimir force, recently measured with high accuracy by S. K. Lamoreaux at the University of Washington, derives from partial shielding of the interior region of the plates from the background zero-point fluctuations of the vacuum electromagnetic field.
As shown by Los Alamos theorist Milonni and his colleagues, this shielding results in the plates being pushed together by the unbalanced ZPE radiation pressures. The result is a corollary conversion of vacuum energy to some other form such as heat."....end of lift...
I dont buy the zero point energy ( the ZPE reference) thing either but I like the rest of it



because they use that word I like so much...push... it is such a lonely word when you think about it..there are no others that says the same... we have lamb , sheep , mutton to describer a beast but there is only one word to describe push and that is...er push..there are not others... is that not curious.. there is no synonym for it...
All I say is we can not at this stage measure the radiation pressure of which I go on about there is no question about that ...but this zero point energy thing is only trying to fit this possibility into the current thinking and give a "point" source for the energy all say is not really there... confusing yes if you fail to admit that the old concept of an eather was to a degree correct... however it was thrown out ..old hat.. but it points in the right direction if you consider it is not static but "flows" at C.
I am now reading all the links from a goggle of casmir to bring myself up to date with it and although not much is actually about what I went looking for it is all neat stuff anyways
