I've been trying out a few variations of the coke can stove ready for a walk along the Ridgeway next week. There were lots of designs to try on the Zen Stoves website. I need something reliable to produce hot drinks and some basic cooking for two people. I've settled on a sideburner version of the penny stove to use with a 1 litre aluminium kettle. The kettle is very light (135g) and has a lid wide enough to get food in and out easily.
The penny stove is ridiculously simple to make - two can bottoms pushed together, five filler holes punched in the top and a ring of burner holes about 15mm from the top. Primer pan and windshields cut from the remains of the cans. These fit inside the kettle for transport. No need for a potstand. I've tried using cider cans and the narrower Red Bull cans and both work well. You do need to use a broad-based pan or kettle as the ring of flame gets pretty wide! Using Red Bull cans reduces this a little. The stoves seem very fuel-efficient and quick - mine will boil a pint of water with just 15ml of meths in flat calm conditions, though 20ml is more realistic. A word of warning though - only use a few drops of meths to prime the stove. Using too much will overheat it and produce a flamethrower which looks spectacular but isn't that all efficient at boiling water
