I always wondered why there wasn't a similar stove on the market: a butane-burning equivalent to an alcohol burner, if you will. Low-powered, ultra-low weight, and useful with a real windscreen. Why on earth is the lightest remote canister stove still 6 ounces, and massively over-engineered?
Planning to go into production?
EDIT: PS if you build such a burner to work in a Caldera cone, may I humbly suggest that you omit feet altogether? If possible, just allow a titanium tent peg to be inserted straight through the center of the burner and into the ground, pinning it in place. No muss, no fuss, and probably more stable than any other stove!
