[Stoves] iCan in a Trash Can

[Jock Gill]

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

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.
