|i remember faintly a story about (big) cranes in russia, where they had a |sequence of three heating devices (from small heater to big heater) |starting in sequence: first a small heater heated a small motor which then |started to drive a generator to heat the tank and the motor of the next |bigger stage and so on... Awhile ago, on the radio news, I heard that temperatures in Alaska got down to -80 (not sure if that's F or C... cold either way!) and basically if your car or furnace stopped it wasn't going to start again until the weather warmed up. Even a gravity-operated oil furnace won't work too well if the oil is solidified... Rather amusingly, however, this news report was followed (after a short station promo) by an advertisement for Royal Carribean Cruise Lines' Alaskan tours...
