The reverse osmosis water maker (admittedly not a new one) on my boat
makes about 1 gph using 5 amps at 12V, so this is about 60 WH/gal.
...

My Spectra makes 8 gph at 8 amps. That makes R/O a full order a
magnitude more efficient in energy terms than the distiller. Of
course, the price of the first gallon of purified water is ~$100 for
the distiller and ~$5k for the Spectra at retail...

Someone sent me an email looking for a comparison. Of course, RO sellers
think RO is best and distiller sellers, like this guy, think distillation
is best. I happen to agree with the latter for the reasons shown on:
http://www.qualitywatersystems.net/education.html
One of my distillers is 30 years old and, though not as efficient and
easy to use as these new countertop models I prefer now, works perfectly
at around 1.8 ppm total dissolved solids after carbon filtration....after
30 years of ABUSE. If your RO membrane gets a pinhole in it, you'll
never know it....until someone gets sick, which is EXACTLY what I think
happens on RO-equipped cruise ships where massive gastrointestinal
outbreaks occurs. All the people on the ship are drinking RO'd
seawater...the common element to everyone that's sick.

I looked but can't find the article I read about bacterial breakdown
against the RO membrane. I suppose many RO interests don't want it on
the net. It was about the bacteria breaking apart under the pressures RO
uses, then the toxins in the bacteria being released, passing right
through the filter membrane into the output side. It was a scary report
I'm sure many would want BURIED....
