Default Rocket stove build...maybe

Went down this rabbit hole this morning. https://youtu.be/fieXrhdO-Eg

He built a rocket stove from what appears to be 4" ID x 1/8" wall pipe. I have 4 and 5" ID casing scraps in stock that are thicker wall pipe (+/- 3/16". IIRC). Any thoughts on how the stove's performance would be affected by the extra wall thickness?

You’re radiant heat off the pipe will take a little longer as it has more mass to warm first, once it’s warmed up should be similar. It will also take a little longer to cool off when you’re done.

Wonder what a hair dryer/blower would do to the performance?

I agree. No real difference in performance, just a very slight difference in the time it takes to heat up and cool down.

As to the hair dryer I think the whole idea of a rocket stove is that they're designed to create their own draft. They're meant to create a fast, hot fire for cooking rather than producing a slow, steady heat for warming a tent or enclosure. My take on it, anyway...

Yes, I'd seen that. A LOT of welding for not much else but practice.

I'd hate to have to split a cord of wood that small. OTOH you have enough caragana hedge to provide small bits to heat your shop for a long time.

A lot of work for a cup of coffee. Now, if it was for a cup of hot chocolate?

More form than function... Really you need a screen and clean out door for
something that tiny that you can turn upside down and shake out?

Too much form vs. function and no KISS...
