Description du film [en anglais] : « There are people who are fighting the high cost of energy by devising ingenious ways to use sun, wind and wood. This film illustrates the nature of these experiments, one of which is the Ark, a bio-shelter that, using natural systems only, provides housing, heat, food and electricity for a family. » -- National Film Board of Canada (source) |
