In this story from NIST, an RF circuit is used "cool" a tiny silicon cantilever— similar to the tuning forks used in 'quartz' watches but smaller — and vibrating at 7,000 cycles per second, its natural “resonant” frequency.
Now in a broad (mis)use of verbiage, one could opine or over-generalize that this is creating "ice from fire"... from wave-energy, in a way.
Well, it is a conversion or transfer of one form of energy to another, and even if it is conservative, it can offer some insight on how other resonant circuits might operate to "bootstrap" thermal or magnetic vibrations into an electrical circuit - and give the appearance of OU when in fact they are taping into a bit of ambient energy.
In this case above the experimenters cooled the miniature lever from room temperature down to -228 C - quite impressive.
I mention this experiment in the context of a ferrite core, where an (un-noticed) one degree or less, delta T change in entropy could perhaps- be converted into milliwatts of another form of energy ?
