Jock,

This is a good goal.  Thank you for sharing.

  Kirk,


  I agree.


  I usually introduce the concept with a single can.  Then add a stack can to show the difference.  It is quite easy to make a single can stove with a rock and a nail.


  I also start beginners with much surplus primary air to insure success.  No failures for the first time you make a small TLUD.   Then I start to introduce the idea of approaching limits to get down to an amount of primary air that will sustain pyrolysis, especially in the early phases when it is just getting established. Primary air will effect quantity and quality of charcoal harvested, amount of ash, quality of stack gas etc.


  The idea in the current PDF is to show that you can go from a single can to a more advanced set of solutions.  I also want to show that the orthodoxy around concentrator rings is no more than one option, and not necessarily the best.  


  Thanks,


  Jock

    Jock,

    I like the trash can idea for all your reasons but especially for safety when working with a group of children.  The stove has some inovative thinking in it but perhaps the inovations add more complixity then is needed to communicate the basic wood gas principles to children.  Dr. Paul Andersons granddaughter had a wonderful little stove at stove camp that was simpler and may more clearly communicate the principles.  It worked well with many different fuels and achieved excelent numbers when tested.  Perhaps she would be willing to share her design with us.  Once the children understand the basic principles then they can learn from your stove how to inovate new designs.

      Fellow Stovers, 


      This is the current state of my natural draft  iCan TLUDs design for use by teachers who want to introduce the concept of pyrolysis, biochar, carbon negative energy and so much more.


      Everything in the document is subject to change and should only be considered as departure points for improvements of one sort or another.


      I look forward to any and all comments and suggestions.


      Regards,


      Jock
