25g canister stove, first impressions

The BRS can work fine in the winter with the copper strip and a natural wind break made from rocks, snow, etc. However if all water is obtained by melting snow it is IMO best to use a JetBoil or other HX pot system that offers much better efficiency for both fuel consumption and speed. The copper strip works with a JB MiniMo.

That strip of metal is enough to keep the fuel at an ok temperature?

Yes, down to -21°F at least.

Wow! That is amazing.

that heat sink idea..... I wonder at what point it's too hot....too big of a heat sink for the ambient temperature?

[cmoulder]

I've done a worst-case scenario (moron) test and they didn't blow up.

But there's absolutely no reason you should be using it above 40°F ambient.

The easiest test is the "touch test"..... if the top of the canister is not too hot to touch, you're golden. In actual operation, it has never even approached this temperature for me.

As with any topper canister stove, don't wrap a windscreen around the stove and canister. Use natural windbreaks (rocks, snow, logs) and there will be no problems.

Not sure what the patent app shows, but Cmoulder should get a piece of the action.....

Thanks for the thought, but alas, too much prior art!

It is IMVHO a significant refinement and simplification of the old heat shunt concept that has been around since about 10 minutes after the first Bluet stoves hit the mountains.

I think the previous assumption was that the shunt needed to wrap around the canister to heat it up, but I found that heat propagated superbly with just the strip.

Maybe obvious but that base under the canister in the cmoulder photo is very important to get the system to work.
Worked for me with a White Box stove at a few degrees below freesing.
