Power failures put things into perspective such as how will one make coffee? Faced with that scenario last month, an earlier plan was executed and an ultralight stove built from Heineken cans. Variants of this stove are legion but after review the Penny was the one. Roughly 15 minutes after starting there was a merry gas jet & boiling water. Coffee was served and food cooked throughout a typical blizzard & blackout; the New England Blue Plate Special. Many thanks to Mark Jurey for his great site.
