Alcohol stove, my latest iteration
After a long period with a very bad back, I needed something to perfect. Here's what I came up with after a few months, and lots of aluminum shavings on the floor. Weighs very, very little. Brings 2 cups of water to a boil in 5 mins, can also be regulated so it'll simmer or bake. There's an optional heat exchanger (a perforated piece of a cigar tube) that'll increase output at the cost of reduced efficiency, and knock about 30 secs off of the boil time. The coke can slice slides up/down to regulate the burn accurately. The top cap cuts the flame from the center, forces it out the sides, and diffuses the flame, making it better for frying/baking. The three pot support legs unscrew and slide into the hollow handle for storage, however, everything assembled will slide into a camping mug. The bottom is double layer with an air gap so it'll work well in lower temperatures, and there's also a primer base for when it get really cold. Burns yellow Heat or Denatured Alcohol. When this sucker is running on high, a stainless steel spoke put into the center of the flame folds in the heat after about 20 secs !! Thankfully, the flame path takes the heat away from the aluminum parts well enough.
