Cassimir's Dark Energy Plate Experiment

I was watching Nova: Fabric of the Cosmos, and there was a part where they were discussing Hendrick Cassimir's dark energy plate experiment. If the plates move, then that is work being performed, right? Isn't it conceivable that this energy is capable of being harnessed regardless of how much could actually be harnessed?

This has nothing to do with dark energy.
 
Hm...perhaps I misunderstand what was said, but I'm pretty sure this was the gist of that portion of the documentary. Would you provide some lay insight on experiment that I am speaking about? I would be much obliged.

"Casimir" not "Cassimir", and that will get you to plenty of online sources including wikipedia. And like Vanadium 50 said... No dark energy involved.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
