Theres really very little to it in principle. You slowly boil the
water, and move the water vapour into something cold enough to
condense it, and it drops into a receiving container.
There are a couple of practical caveats. First when people first make
one they usually greatly underestimate the amount of cold surface area
needed to condense. Second, as someone pointed out, be careful what
materials you use. Glass and stainless steel are good.
Re the condesnser, there must be 100 ways to improvise or manufacture
one. Stainless steel will condense at a much better rate than glass,
glass is a heat insulator after all.
At a push one can distill water using just kitchen equipment and a
stove. One of many possibilities: a pan heated very gently on the left
side. A glass chopping board resting on the pan, propped up on the
left so it slopes down to the right. A container to catch the drips.
The limit with such kit is always slow condensation, you must keep the
heat very low to allow the condensing to work efectively.
Of course de-ionising is easier.
I would ask alt.solr.thermal about a solar still too. Ever so easy to
make, and they run nicely, with no power source.
