Biochar app

Touch screen to light. 
Move flame to center log. 
It will heat to 100C and then blow steam. 
Keep heating until the moisture content goes down to zero. 
Steaming will stop as self ignition starts. 
You can stop touching now. 
Heat continues to rise as wood slowly burns away leaving a bit of ash.

It actually doesn’t do biochar … Yet

I have to think of oxygen detection and better heat detection
