Microwaves in the Watersphere
From The Crop Circle Ship Wiki
Microwaves are shown in Layer 3 of the Watersphere. It is highly likely that they are used as a catalyst for Hydrogen and Oxygen to turn back into Water at this point. Also see Watersphere Process in 1995. It also appears that these Microwaves originate from inside the Octahedron, moving outwards over the Magnetic Rings, see Magnetic Rings and Microwaves.
In the next 4 images, notice the multiple circles associated with the Microwaves in each case.
From Secrets in the Fields (page 38) (Freddy Silva) [in reference to the image below]... "in this formation the lay of the crop in the outer ring transformed from a linear flow to an unusual sine wave.
From Secrets in the Fields (same page, 38) (Freddy Silva) Colin Andrews' description of the formation below: "The surface swirl was anti-clockwise and towards the center, which is in itself unusual. Most circles start at the center and move outwards towards the periphery, with the plants lyring together. This one had a top and bottom layer of plants, flowing in multiple directions. The surface plants had a brushed effect and consisted of a thin outer band which flowed to the periphery; at the band's inner edge, the plants diverged toward the center and flowed inwards toward a perfect center point. The point where the plants diverged, one towards the center, the otehr towards the periphery, formed a ten degree angle. When lifting up the surface plants I found two sine waves, 180 degrees out of phase and each emerging from the peak of a single sine wave around the outer band. (Andrews and Delgado 1990)"
