Freezing concentrates sugar (maple sugar), alcohol, and salt solutions as efficiently as heating distils water or alcohol from solutions. Open pans of maple sugar can have the surface ice removed regularly (each day) until a sugar concentrate remains. Salts in water, and alcohol in ferment liquors can be concentrated in the same way.

Bill MollisonIf you let people loose in a landscape and tell them to choose a house site, half of them will go sit on the ridges where they'll die in the next fire, or where you can't get water to them. Or they'll sit in all the dam sites. Or they'll sit in all the places that will perish in the next big wind.
