Orbital Wien Bridge Oscillator

  [vote for,

A Wien Bridge Oscillator is an interesting negative feedback circuit that often uses a non-linear element as part of it, for example, an incandescent light bulb (which changes resistance according to how hot it gets) (and is also microphonic, which may or may not be a desired feature).

I propose a giant Wien Bridge Oscillator be set up through arrangement of planets in orbit around the sun, such that the heating and cooling of a chosen planet acts as the non linear element. It may work out that the entire solar system as we know it constitutes just enough components to form such a Wien Bridge Oscillator.

       //It may// or then again it may not. I think you'll find that Jupiter's massive inductance will basically make the system ring, but not oscillate.

       From the title, I thought this was going to be an idea for a rotating foot bridge somewhere in Shanghai.
