[Stoves] Charcoal Rocket Stove

[Saibhaskar Nakka]

Dear Dean,

I have designed "Avan Stove" http://e-avanstove.blogspot.com/ with primary
and secondary air facility. It's performance is very good. I can control the
primary air flow in this model, and it has many other advantages of using
different types of fuels. Dr. Paul had seen it during his visit to
Hyderabad. For details please see the link:
