With 0.5mm holes, you will get faster jet and better air mixing. The flame will be shorter and hotter, similar to a gas stove. The pressure and temperature in the stove will be higher though. So you need to seal the fuel port. And JB weld can't survive the temperature anymore when using 0.5mm hole high pressure design.
@@tetkoba 0.5mm is hard to do. It needs internal pressure equalisation, baffles against pulsing, machined parts and insulation. But it is very efficient and powerful. Hopefully I can find my old stove from 2006. It uses 16 0.5mm holes in a central 10mm tube. The flame looks like the star on a gas stove. I gave up on them, because the materials broke down from stress after 3 uses. The high pressure alcohol inside reaches about 400°C. But it's powerful like a gas stove.
If the pot isn’t a fixed requirement, maybe consider using one of those jetboil pots that have heatsinks on the bottom? Those should absorb more of the heat from the flame and give a shorter boil time
Yes any type of pots are OK. But I want to know difference with or without heat collector. Remark, the heat collector(heat exchanger) will act as heat sink If the flame is not always on fin.

Awesome. Keep it up you almost there. I love your channel
the tornado makes it slower? how?

At 0.5mm, the resistance is too large and the efficiency deteriorates. Practical from 0.7mm. This is my rule of thumb.

Heat inevitably lost to the side and travels upward without heating the pot, would you consider adding a shield?
No.Since this is a project to maximize the firepower of the stove alone, I am experimenting without the windshield.
That was surprising.
