The idea here is not new - it is old and I stole it from my Bibler hanging stove. You can take any two pans from a set where one is a size larger than the other and drill holes in the larger pan and attach a stove burner inside it. The flames bath the smaller inner pan in a very efficient manner and wind on the outer pan doesn't cool the inner pan. Generally these kinds of stoves are for high altitude use and can be hung from small chains attached to the outer pan, which aids in hanging it from a piton or inside your tent, and they have compressed gas burners which work really well at high altitude, but suffer a lot from evaporative cooling at lower altitudes like below 12,000 feet. You need to be sure that there at least 3 large holes [like an inch and a quarter, or 4 one inch holes] to allow enough air to get to the burning fuel so carbon monoxide isn't created.
The weight of the outer pan should be around 5-6 ounces - not too heavy for a windscreen that also increases the efficiency do to the shape thing - there is a thin even cavity all the way around the inner pan which requires less burning gas to maintain a flame filled state.
My favorite homemade model uses the bottom half of a 7" diameter Evernew Stainless Steel pan for the "windscreen/firepan" and next smaller sized Evernew pan in Titanium. This Windscreen/firepan/stove burner combination weighs 8 ounces.
Disclaimer. I do a lot of foolish crazy things like cooking in my tent and solo rock climbing - do not attempt to do the things I do. DOING THIS WRONG COULD CREATE A CARBON MONOXIDE HAZARD.
