That is a really neat effect. Basically if you can put a water molecule inside a flat field it lines itself up with that field and can be compressed. I would bet this has an impact on Graphene based desalination efforts as well.
That type of filtering was also something that I had in mind.
It would additionally be interesting if the water would react to EM fields and confined spaces in a way that allowed for a 'micro' pump. Such a system might be able to operate in zero-g and thus be useful on extended space missions.
That is a really good observation. Microgravity environments have an issue with the lack of sediment settling, and while the current centrifuge system are effective, it would be really interesting if you could separate the precipitates without spinning everything.
