Boilerwerks Backcountry Boiler

Ultralight volcano kettle style stove. Superfast and efficent!

The Backcountry Boiler by Boilerwerks is an ultralight variant of the volcano kettle developed ages ago in Europe.  It runs off of found fuel out of the box and with the addition of their FireFelt accessory will boil 16 oz of water in 4-5 minutes on about 1oz of fuel (depending on altitude, etc).  It can also be used with esbit tabs if needed.  Add the Boilerwerks pot stand and you can boil your noodles in a pot/cup on top of it at the same time.

The only downside I've found is that the inside of the chimney can get coated with residue from the found fuel (i.e. wood tar). This doesn't appear to affect its functioning, but it can carry that woodsmoke smell with you.

Well worth checking out.
