Some five hundred years ago this was one of the purest waters available on this planet. It was called ultrapure-water and was unfit for human consumption. Super-clean water tastes flat, heavy, and bitter. Just one glass of water would leech out valuable minerals from human-body and is nutritionally debilitating. The metabolism would go haywire and the bones would be just chalk unable to bear body- weight.
Ultra-pure water required 12 filtration steps beyond RO. For those of you with a technical bent, final filter in making UPW has pores that are 20 nanometers-wide. The 20 nm-filters were inspected using a scanning-electron microscope. The filters should have nothing in them.
At a time when safe drinking water was a scarce commodity, more than ten million gallons of the cleanest possible water was manufactured each day. It was so clean that it was used as an industrial solvent, absolutely central to high-tech manufacturing but not safe for human consumption.
It was used for making information-technology equipments; and the resultant chit- chat precipitated the catharsis.
Dependence on objective material science did not allow them to use their inherent power of cosmic communication
