It's a theoretical theoretical free lunch :-).
(Casimir effect).
Several ways of looking at what happens - you described one of them.

Buzz "Contact Light" Aldrin (THE Buzz Aldrin) wrote  a SciFi novel in which 
the primary means of Starship propulsion was using zero point energy 
extracted via the Casimir effect. It pays to keep up the maintenance on your 
plates, according to the story :-(. An OK story.

       http://en.wikipedia.org/wiki/Casimir_effect

As you say, getting it out is the trick. Once the plates are 'stuck 
together' you are resisted by the forces which provide the power in the 
first place.

At the risk of carrying an analogy too far, it seems very similar to the 
problem using to the effect in question in this thread - magnets can 
approach from a great distance and deliver net energy as they are attracted 
to each other. BUT once you need to separate them you need to put in an 
equal (or greater) amount of energy. That's why the "magnetic gate" and the 
current magic motor CANNOT [tm] work.

Various apologies to Ben / Poor Richard / Mister President ... were 
scattered around.
And note that "can not" in fact is defined as meaning "have never [to our 
knowledge*] ever been veraciously reported".

* - minkly defined.

About 1 atmosphere equiv (100 kPa at about 1 atomic radius) they say.
