I have two of the smaller backpacking wood stoves that work very well: the titanium and stainless steel MK1-UL by DarenN and the stainless steel folding Woodgaz wood stove by Zelph.
"I'm glad that US patent law allows me to share and protect".
This, itself, is a primary reason U.S. moved ahead so swiftly in invention. Some people contribute, and, others may have a different idea inspired by the discussion.
"I do plan to make a few modified versions over the summer, though".
"Does everyone who expressed an interest see nothing about the first version that could be improved"?
I would say, any burn tests?
Over at bplite forum, the characteristics of the fire itself are considered. The volume of the wood stove is an imperative to function, as well as size and placement of holes, height of the fire grate, height above the flame, and such.
Then, get the specification of the metal and thickness of foil worked out.
Does your college have students in metallurgy or materials science classes or instructors teaching those subjects? The people good at that get top pay and it all seems to go to either the military or to "proprietary information". That is why during your college years is the best, if not the only time, to find these things out.
If not, just try different foils available.
Discuss results in a forum specifically of stove builders, as well, like bplite forum.
My college had a sequence of required courses in drawing, making a prototype and writing a patent. Signed, dated, bound notebooks (no pull-out pages) are a start. It is for your protection: "sign and date" every page of sketches, scribbles, and, notes.
It is the roll-up design that will likely get your patent. For patent purposes, because it involves art, as well, I suggest the design patent specify small differences like a Victorian or Art Deco motif, for example, are included. It is the hole size and placement, volume and the height and distance between involved that make it function exceptionally well.
I had fun with Myst when it came out, but steam punk? ;-) There are people who just love everything Victorian. Art Deco would be my choice.
I want one.
