Create a waveguide. The waveguide allows only certain wavelengths to constructively interfere. A Mach-Zehnder-like modulation will disguise the amplitude so it will appear chaotic, even though it isn't. That's why the [ENSO model shown above](https://forum.azimuthproject.org/discussion/comment/22819/#Comment_22819) works so well. The input is already highly structured as it is generated from a highly ordered tidal time-series


The amplitude as shown in the spectrum matches very well the accepted ordering of strength of tidal forcing, with the top 3 being the Mf, Mf', and Mm signals (corresponding to 13.66, 13.63 and 27.55 days). This is how the equatorial Pacific waveguide creates negative entropy.

We can likely harness this energy on a large scale if someone wants to fund a Panama-canal like structure along the equator, and let the moon and sun cycle up some forces with El-Nino intensity levels.
