More water mystery: H3O2

Layers of EZ (exclusion zone) water next to hydrophilic material
From Prof Gerald H Pollack's TED lecture

Water appears so simple, yet ...

A few days ago we looked at the Mpemba effect, whereby hot water freezes faster than cold. As yet there is no single, universally-agreed explanation.

Today AK Haart shows us a TED lecture by award-winning Professor Gerald H Pollack from the University of Washington, about the "fourth phase" of water (apart from solid, liquid and vapour). Truly fascinating, especially in its potential uses (e.g. desalination, purification, energy production):

And just this last Thursday there was a BBC4 programme about plants, which at one point showed that inside leaves, the light-utilising chloroplasts that make starch actually move about in response to sunlight, seemingly to utilise the energy most efficiently.

The clip (available only for a few days more) is here:

Chloroplasts "jostling for position"
from "Botany: A Blooming History" (BBC4, 17 April 2014)

Could the electrically-charged layers of water described by Professor Pollack explain this movement?
