On a previous thread Shafferpilot mentioned the necessity to increase burner to liquid surface area in order to facilitate boiling on a large scale.
I stole this idea (and if I decide to go through with it, the parts) from an RV water heater.
Another problem may be trying to weld to the thin aluminum pot.
BTU's can be controlled by burner orifice size and an adjustable high pressure regulator.
If anybody has any background in - thermodynamics, engineering, or just messing around with this type of stuff - and could help me design this, please let me know!
I'm looking for a system to handle 25-30g and from what I've heard, a standing burner won't cut it.
