Greetings, I have a question about Zero-Point energy. I know that is occurs due to the Casimir Effect which is a product of putting two metal plates very close together, so that large wavelengths of background radiation cannot exist in between the plates. The result is a EM vacuum that excludes some wavelengths and sucks in others. My question is, how close must the plates be? And what wavelengths get sucked in as a result of the vacuum and why? Also, how much enery in Joules or Watts does this theoretically produce and does the distance between plates dictate the amout of output energy? One last question is, what are the plates made of, aluminum, cadmium, tin? Please enlighten me, I know there are some closet geniuses posting here, now would be a good time to show yourselves. thx.
