p80 TLUD design test water boiling test

This shows the full C4 configuration with the gas grate in place and a 4.7 liter pot with 2.5 liters of ambient temp water in it. The water started at about 12 degrees C. The pot was placed on the C4 13 minutes after the fire was lit. The water boiled in 30 minutes and was kept boiling for another 36 minutes. The wood gas ran out just two minutes later.

The above details conform to the specs for a 2.5 liter WBT.

Note: I do not believe the top coffee can needs any holes in it. I will test this when I get my hands on another one.
