Catching up with a mail backlog, after 10 days on the farm. (Winter's looming, but there's 10 m³ of firewood under cover now, and another 8 stacked in the forest.)

That could be why we've kept ours (out on the farm) on the veranda these last 52 years, despite the fact that the old house had an exhaust vent to the roof space over the fridge alcove. They were kero jobs for the first 35 odd years, and one gas fridge has done the job since, running for months on one large gas bottle. After a couple of decades of service you still have to be careful not to wind the thermostat too much, or it freezes in the lower compartment as well. You do have to clear the soot out of the flue once a decade, with a brush first, then compressed air. I didn't know there was hydrogen in there - I thought it was just ammonia and water. (Keeping hydrogen contained for decades is no trivial challenge, IIUC.)
