CS>Watercone solar distiller

[Matthew McCann]

If you have an a bottle/jar/jug cutter (a popular arts & crafts
tools in the 1960s) and a free supply of glass bottles and jars,
you could make an array of small-scale water distillers
for next to no cash outlay. Its just a matter of using
four different diameters that can fit inside each other like
Russian nesting dolls.
