Last time I asked about a stove design, I got some good feedback here. So now I am asking about a new stove design...
Seems the biggest concern with my Ion stove was it was slower than some people wanted. So I set out to build something that would boil the **** out of water I actually made a stove so hot it was melting my windscreens. This led to switching to Titanium to replace the windscreen and Tipod stand. As I was working with it I said to myself:
"Self, you could also burn wood in that thing, that would save fuel in that you would only need to use alcohol when you were unable to find some good wood."
So I modified the design some and made a prototype from aluminum since I am running out of my last batch of titanium. It seems to have worked. I can boil 16 ounces of water in about 4:00 - 4:30 with around 0.5-0.75 ounces of fuel.

(note, these pictures are of a very rough built prototype)
It takes about $25 worth of titanium to make the stand/screen. Add to that a stove and labor, it would cost about $45 to sell one stove. The stove is made to work only with a pot that is about 4.75" - 5.5" in diameter - I have been working with the Evernew 0.9 L pot.
The cool benefit though is the stove can now burn wood similar to this stove: http://www.trailstove.com/index2.html except that mine would be able to come apart and nest inside a 5.5" pot and the stove, blow tube, and windscreen/stand should only weigh about 3.5 ounces.
I figure a packing list for a stove like this would be something like this:
3.5 ounces Stove
0.6 ounces for a 4oz fuel bottle
3.2 ounces of alcohol (4 fluid ounces)
2.5 ounces of fire starter (10 Vaseline soaked cotton balls)
0.2 ounce for a small zip lock to hold the cotton swabs
4.0 incs for a 0.9 L Evernew pot
0.8 ounces for a Scripto lighter
0.8 ounces for a pot cozy
15.6 ounces total
I figure that is still less start weight than a canister stove with the ability for unlimited cooking as long as you can find something flammable.
So, is it worth $45 to someone to get something like this? Should I even mess with it?
