I suspect (though I haven't run the numbers) that a refrigerator run by
a pedal generator isn't a self-sustaining. That is, it would take more
energy (in the form of food) than there was food in it. Using a pedal
powered freezer to make ice to keep the fridge cold would be an even
worse energy balance. I think we would all quickly learn the benefits
of root cellars.
I was told, while being given a tour of the facilities at The Chewonki
Foundation ( http://www.chewonki.org/ ) that one of their cabins had
decided to use only energy that they personally generated or got from a
small bank of solar panels. The girls in the cabin became very frugal
when all their energy had to be earned on a bicycle.
Amusingly, the cabin had a large array of PV panels on the roof, and I
thought that was what was meant by 'small bank'. But those were
actually NOT for the cabin, but for a larger building, The 'small bank'
was a bunch of panels constructed (by the inhabitants from individual
modules) which may have amounted to a couple of square feet altogether.
