I was reminded about water pseudo-science during a discussion today. If you are curious about terminology seen at some water-from-air system provider's websites---Pi Water, Alkaline Water, and so on, I recommend visiting Stephen Lower's website. He is a retired chemistry professor from Simon Fraser University in Burnaby, Canada.
I have been researching and developing drinking-water-from-air technologies since 1984. As a physical geographer, I strive to contribute an accurate, scientific point-of-view to the field.
