Hello Gentelmen,
Let me first introduce myself, I am Jeff, and I am the one who designed this stove... I see I'm a little late to the party, but better late than never, eh? I see some general unlove for the design it but hopefully I can alleviate some of the speculation, and maybe sway some opinions.
I do really appreciate all the feedback, and was a little surprised it was tread creation worthy on a ULbackpacking forum... for some reason I decided to google search "HexStove" today.
The concern about the efficiency because of the "base" is legitimate. I can understand that you would think it would choke it off. But the design of it provides so much interior volume that when you can fill the entire cavity of the stove with wood fuel, assuming you don't over fill it... it creates a sufficient convection current that it draws air from all 6 panel's slots, and if you rotate the door towards any breeze at all it takes off like a rocket! ha. When the stove is set up in the "FireBowl" configuration, it uses the grill grate in the bottom to elevate the coals. An air gap is provided by the top of the door.
The weight is a lot, I'm not going to deny that... It was the first design, and as an engineer continuous improvement is a must. I have my "Hex40" as the main stove now which scaled down version (%60 smaller) it is what i use on an actual backpacking trips. it weighs 9.25oz. This one is cheaper too, it uses so much less material!

Personally, I'm not afraid of 5.5oz (TI emberlit) Vs. 9.25oz (Hex40)... But some are... so I've got an answer for you guys too. A rev.3... This will open up the air slots (provide more flow too), it will have more grate opening, and a few bigger radii to chunk off more corners. This should bring the weight of the .036" SS down into the 8oz range. I will be prototyping this design from the same ga. Ti for now ONLY ONE... for myself! (one off material alone it $70 FML!)
I will report the weight once this is completed... but given the densities of each material it calculates out to possibly be UNDER 5oz!!!!!!!!!!!!!!!
I did the "math" I'd need an order of TEN (10) to make them and sell them for $55 from Ti. I also have a nylon pouch with a draw string I sew up as a carrying method included now.
