[NewCandle] Physical Methods Of Water

[Nick Reiter]

Re: magnetic water separation...in 2003, a couple of
us at the lab played around with swirling sea water in
an annular track over a big donut magnet to see if we
could separate ionic speacies and thus desalinate the
water (which we tried to tap out of the center of the
track using a syringe).  We tried to gauge our success
by volume resistivity of the water.  Didn't work very
well, and I presumed that we would have needed a MUCH
more powerful magnet at the time.

About a year ago, I found a paper from an Israeli
group describing a desalinator using a long serpentine
track with magnets and side port brine extraction. 
They apparently got it to work!  As usual, I stuck it
away on my work puter, will try to dredge it up when I
get back to der lab.  Overall, my life story, always
too little too early;)
