yeah, that's pretty interesting. I'd like to hear more...
off topic (sort of like trapper's microwave) I was reading yesterday about a way to make maple syrup "raw", in what used to be called 'the eskimo' way
(this refers to their cutting sea ice in the winter and keeping it on land in the brief summers, as a source of fresh drinking water.)
Basically, you freeze the -in this case- sap, and then thaw it and dispose of some of the liquid, refreeze, and do the whole thing again. The author of this Mother Earth News article from their archives online (the '70's) figured he had about $1.48 that he could squeeze out of the family budget (I love these necessity-breeds-invention stories!!)and lived near some government land. He located three trees and collected 5 gallons sap. In the end, after NOT ruining his kitchen with steam from boiling sap, he'd spent less than a dollar on some drinking straws and a few plastic food bags. He ended up with a pint of RAW maple syrup.
And then ran an experiment to check to see how much potential syrup he'd actually lost in the process. It came out to something very minimal...and didn't take long, or much in the way of hydro.
Reading this, I was thinking: there's something in this! Someone should pick up on it. Run with it. Anyway-- you see how little that has to do with the fact that you have no refridgerator?!
Sort of like a double negative -- making a positve?
