I already have fixed and portable firepits, along with a couple of small wood stoves that are sitting idle.

More than anything, it's the smoke reduction aspect that grabbed my attention. I have a lot of wood of marginal quality that needs to be burned down to charcoal (not ash) for the garden, but that's a smoky business and it really gets to me these days.

I've been interested in rocket stoves for a long time. The main attraction of this one is that it's ready to go, and meets the minimum size for my needs. But I suspect "smokeless backyard firepits" may be flooding the market en masse in the next couple of years, since it's not a patentable technology.

This one is way overpriced IMO. So I may be down at Cabelas with my phone camera and a measuring tape. My father is retired and loves to weld ...
