[Stoves] Mewar Angithi: An In Situ Modification of the TSH as a Solution to the Problem

[Dr.-Ing. Dieter Seifert]

Francesco,

for a complete combustion a griddle is helpful, but for attaining a high 
efficiency a skirt is also recommendable.With the Ben-stoves 
(http://solarcooking.wikia.com/wiki/Ben_3_Firewood_Stove) I tried to 
combine these measures and I propose to combine the stoves with 
heat-retention cooking 
(http://solarcooking.wikia.com/wiki/Heat-retention_cooker) which is a 
useful and totally clean cooking method.

With kind regards,

Dieter
