Re: [MLUG - DISCUSSION] H2O -> H2 & O3 ???

["Christian M. Cepel" <EMAIL:PROTECTED>]

So if we could store it and transport it to high altitude and release 
it.... assuming in sufficient quantities, it might do some good?

What about something to bind those Cl atoms at altitude?  Could we send 
up sugar and have it come back down as Splenda?  (I'm kidding here).
