Dan – R&D takes time. Excited to see where you are able to take this.
For sure R&D takes time and haste makes waste. Titanium sure is $, mistakes are costly.
I spot welded some vortex generators to the bottom of the ribs, now to do testing over the weekend.Jun 8, 2019 at 1:12 am #3596738
Wondering if removing (several?) small sections of the ribs mid-run to allow movement of gasses between the compartments would facilitate a stonger vortex? And if it did, whether the complication was worth any improved performance?Jun 8, 2019 at 12:28 pm #3596779
I’ll cut a section out of each rib and let it do it’s best. Every little bit helps.Jun 8, 2019 at 5:47 pm #3596820
I made 2 cuts and will test for sign of heat discoloration around the openings. Need to replenish my canister supply first.
This evening will do some water boiling and eat Mountain House for dinner.Jun 9, 2019 at 11:48 am #3596896
Dan – if the snipped out sections “leak” and cause a problem, could a section be snipped perpendicular to the fin and rolled down similarly to a standing seam roof? The 2 cut ends could similarly be folded at 45 degrees to nearly completely seal everything back up.Jun 9, 2019 at 3:55 pm #3596910
After I made the cuts, I used a steel wheel brush to smooth over the cuts and for the most part, sealed the open area of the rib. Standing seam would work but probably a PITA to form. Thanks for the suggestions. I’ll do testing today.Jun 11, 2019 at 8:42 pm #3597235

I received the initial version (no vertex generators) from Dan (Thanks!).
My quick impressions from a couple of test boils…
This will be an excellent replacement for any regular canister stove. At 1.8oz for BRS stove + screen, it is lighter than my Soto Amicus and should function much better in the wind. The ergonomics of the system are very good.. it is easy to setup, takedown, and store. The handles stay cooler than without the HX Windscreen.
As a Jetboil replacement.. no. To get sub-3m boil times, I had to run the stove at a pretty high output. The HX Windscreen glowed red in spots and so did the stove arms. A lot of of heat was shunted to the fuel canister. Maybe a a bottom disc to shield the fuel canister would fix that, but I would still be concerned about fuel consumption.Jun 11, 2019 at 11:50 pm #3597272

Whoa, this is getting high tech…Jun 12, 2019 at 7:23 pm #3597441
The improvements are coming along nicely.
Because of the recent finding by Ryan and Hikin’ Jim concerning the failures of the BRS3000T, I ordered some Electicity Ultralight stoves for testing. Want to see how well they perform within the full size windscreen heat exchanger. I like the 4 pot supporting legs better than the BSR’s 3 leg.
The added weight of the 4th leg is insignificant when we think in terms of safety.

Love to hear about how the stove goes. Also photos.
3 legs vs 4 legs: agree strongly. A 3-leg support is much less stable than a 4-leg support, for simple reasons of geometry. My latest stove designs go for 4 legs.
