It would certainly be interesting to test and see. I've been wondering about the effect of vortical action on deuterium levels, like the action of streams a la Schauberger. But the higher altitude the water the lower the deuterium count, it's higher at sea level, at least according to what I've read. There's a couple puzzles with all this rolling around in the back of my mind. Loojing at a few trails & will report anything useful
