    Folds flat(ish) - yes indeed.
    Total weight is ~85 g.
    Fuel use for canister stoves depends on two things: pot dameter (narrow pots lose flames up the side) and power output. Run any stove hard and it is inefficient. In the mountains I typically use about 30 g of butane/propane mix per day for the TWO of us. That figure comes from many month-long walking trips.
    For winters in the snow, I double that figure, because it takes as much energy to melt a litre of snow as it does to boil it.

    Minimum pot diameter is about 100 mm. That is a rather narrow pot. I prefer larger.
    There are 4 legs instead of three because it is much easier to tilt a pot over with only 3 legs. It's a geometry thing.
    The legs are 0.8 mm 5083 aluminium sheet, folded to a right angle, bolted down and machined to the shapes seen. The Al sheet is soft, but using pulsed misting (kero + olive oil) the cutter stays wet and there is no BUE.

    I am currently machining up another 2 dozen stoves for sale.

    Cheers
    Roger

    That's very impressive!

    We're probably the only group that understands that thought process. You managed to find the holy grail though and get it to pay for itself , congrats, and nice stoves.

    On the right we have Version 4, with a (fairly) quiet burner. More complex aerodynamics. I have skipped V-1, V0, V1 and V2.

    Very nice ... very professional looking. Market worthy. It look like it folds up into a flat-ish form. How much does it weigh? How much fuel does it use & how much does the fuel weigh? What's the minimum diameter pot - it's hard to judge it's size?

    Are the aluminum/aluminium legs CNC'ed from blocks? Why 4 legs - I would expect 3?
