I tried out the cloud evaporation by focused intention thing after I heard about it, Amos, and I was quite surprised to find that it actually worked, provided I focused intently enough on the cloud in question and didn't let my mind wander or get distracted or bored. I dispersed quite a few smallish clouds into clear blue sky. That was back in the late 70s/early 80s It certainly raises some interesting questions...

I wasn't all that confident about it, though, so I only took on rather small and not very dense clouds...as I felt I didn't have enough "oomph", as it were, to disperse the bigger ones. I did manage to nibble away some holes in the bigger ones, but that was about all I felt like taking on at the time.

Then this Indian guy I knew said one day, "Why are you bothering the clouds? Why not just let them be?"

I thought he had a good point there, so I didn't do it anymore after that. ;-) Anyway, it was a fair bit of work in its own way, and to what purpose?

And I can just see BillD's mind writhing around like a snake on a hot griddle now. Heh! He can't stand this sort of speculative and unproven, airy-fairy, unverified stuff, stuff that hasn't been given the official stamp of approval by the National Bureau of Authoritative Science or the Federal Bureau of Bean Counters or someone else like that. He will have a very hard time resisting making a corrective comment or two about it to set me on the track back to reason and sanity... ;-D
