Tear up birch bark into little shreds said a guy who's started a lot of fires.  Will give it a try tomorrow!

Texas Food Forest And The Results Of Good Design

From Geoff Lawton s email, link is to permaculture institute.  Could be a pretty specific match to your climate!  Or at least a resource for help. 

How's it been going so far?

This runs on Rocket Combustion Technology. Once the fire takes off there isn't any noteworthy smoke for the duration of the burn. All that smoke combusts to increase the heat in the oven.

I would definitely like to see PDF plans, especially with a few variations [smaller models, one with the sunken burn tunnel like Erica mentions on one of the videos in the other Rocket Oven thread, possibly one that is heavily loaded with mass for the purpose of being a hyper efficient form of the traditional pizza oven for a community, or a family that likes to do massive cooking once a month and freeze meals in advance, or for Pizza first, then bread/pie/etc followed at the end with a slow roast or stock pot.

Congratulations on the record rapid funding Paul.



Thanks Kurt, I get that idea but for the 11 minutes heating up to pizza temperature is it smoking or just the first 30 seconds or so?  5" is what it took for the Yonkers fire department to come put out one of my projects, a few years ago, and that was more rural than where I am now.  If you can direct me to info on a fix for this I'd be most appreciative.   Thanks.

I'm excited!

Ok, getting it lit directions I googled worked but only with putting biomass in the top down the chimney, so that's a part of why it got so stuffed up.  And to use pitch wood (ashy and creosotey, I gather)

Is there a better way to get it going?

Yes!!! Funded.

Thanks Paul, 3 weeks is awesome!

Ok I second Bill's thing and suburban smokeless solution--i don't know enough about it to know if it's realistic but to keep the smoke to a cookout level.  Ideally it should be less--the particulate emission is especially an issue ecologically in urban areas.  New scientist just ran another article saying people have to stop burning wood--though not examining the embodied energy of natural gas.  But if there's a way to reburn that smoke it helps.  Thanks.

Im off grid-ish here and lots of other stuff vying for attention, so could use a little boost--what should I be looking up for handling ash buildup in my #10 can style rocket stove...? It barely boiled two kettles of water so far.  It's only for cooking, and mainly proof of concept.  I keep finding info for heaters, I'm not trying to heat people just soup. 

The design is more or less the approveccio one except I couldn't get a rectangular big can, just a #10.  (We have a rectangular can that had paint remover... isn't that rather toxic even after burning out the paint remover?)

I'm probably doing a lot else wrong, but it's temporary and operating in rural area.  Just trying to show people we can do things without propane, using our surplus of twigs.

Thanks so much!

Way to go! Can we get a download of the raw footage now? What would make that worth it you time and money-wise??  Wanna get building.  Thanks.

Looking for leads on building wofati-ish on bedrock/boulder slopes and lots of trees.  Emphasis on the freaky cheap (probably no dynamite involved).  Cold climate, southwest-ish slope, steep (50-1000% grade I'd guess, but a few flat spots, wooded).  Thanks!
Looking forward to it!!!  The kickstarter, not sure I have anyone to send the link to

one idea--

youtube channels or comments on youtube

Maybe you should post a comment on the youtube review of 6 backyard pizza ovens.  Saying you can a make quality pizza oven with a lower ecological impact and less cost than the rockbox or whatever it was called.  It might look spammy to have a bunch of people commenting with a link to a kickstarter.

I don't know the rules about putting links on youtube, anyone know?  if you can't put a link, then saying "there's a video coming out soon from Wheaton Labs" would give people enough to web search.
