Give 3 ideas for very speculative setups that may extract ZPF/quantum vacuum energy that you think have high chance of success despite scientific consensus and may result in large portion of the ZPF being extracted (0.1% or more per cubic meter from the total ZPF per cubic meter). Make sure none of the setups is about NAME_1 effect or if it is at least make sure it is easily achievable. That is: each of the setups should not be too hard to be implemented and can be done "at home" so to speak even if externally bough materials may be needed. What do you think humans have been missing so far? It can be anything.
