>do you get the water in and out through the little hole shown in the first photo? I cant really see the need for more efficient use of fuel with free fuel such as wood, at least if it costs weight. The pot I use with my home made woodstove weighs 30 gram. Is there other advantages to a kelly kettle?
Hi Derek, My new design has a much larger opening for the water to be poured into, and a lid to close it with. Availability of wood isn't always good in the british climate and terrain, I know, I live there too. So my new design is for alcohol only, and it's pretty efficient at 53%, using just 12ml of fuel to boil half a litre of water. The unit weighs 82g including the stove, but I can make a lighter one around 40g which is only slightly less efficient.
The main advantage of a kelly kettle is it's wind resistance. Most alcohol burner/ pot combinations struggle in blustery conditions, but my kettle design is fully insulated and unaffected by wind. When you add the weight of a good windshield/pot stand to a pepsi stove, pot and lid, it adds up to more than the kettle by some margin.
