Dear Kevin,

At the end of the video there is a chart comparing the Jiko and the
'charcoal Rocket' for fuel, energy, CO and PM.

Best,

Dean

The chimney used in the Video is hardly a "Rocket Stove"... it is simply a 
chimney above a charcoal bed.

Dean shows the CO going from 8 to 1800 to 8 ppm CO in the video, but he 
doesn't give any indication of what the performance would be without a 
stack. There is no basis in this Video for claiming that the stack reduces 
the CO.

The data shown on the Video does not match with the data shown at this site.

Construction details at this site don't match the appearance of the 
insulated stack shown in the video.

Am I missing something?
