I'm doing a thermodynamics project on possible future energy sources. I've decided to try and find out if you can extract heat from vacuum energy. My initial hypothesis was that by placing to plates close together creates a magnetic attraction due to the casimir effect, which would create heat do to the magnetocaloric effect. I would think that you could build a rotary system off of this to create in essence free energy, but after running through the numbers, the amount of energy produced would be very small. My second thought would be by using two plasmas, you could have two sheets which collapse into each other, absorbing vacuum energy, producing extra heat. However, I'm looking for a system which dissipates heat directly into a working fluid. My third thought is that perhaps, cavitation and turbulence creates more vacuum energy which is in turn absorbed by the fluid. My thought is that the work required to expand and contract a fluid would completely turn to heat. The expansion would create vacuum energy, and the compression would absorb it. However, I am almost postive there is an equation which shows you lose energy in turbulance, and perhaps this is related to the energy required to expand a fluid to "create" vacuum energy. Any thoughts?
