This is a typical youtube-style metal "rocket stove", with no downdraft at all. As Max says, because there is no insulation, it cannot reach the truly high temperatures needed for destruction of chemicals. I would not claim it is safe, even though there is no visible smoke, until you have tested the exhaust. It hardly even qualifies as a rocket, as the essence of that is an insulated combustion chamber that keeps all the heat inside until combustion is complete.
This style of stove is excellent for cooking, and may work better than a standard woodstove for instant heating, but is far less effective than a rocket mass heater at keeping a space comfortable day and night.

In this video i show only, you can burn plastic with wood in a rocket stove ..
I don't say You should do that or it is a non polluting burn ...
In addition to the chemicals listed in the table, wood smoke also contains a large amount of unreacted air, carbon dioxide . It contains a variable amount of mold spores. VOCs are volatile organic compounds. Aldehydes found in wood smoke include formaldehyde, acrolein, propionaldehyde, butryaldehyde, acetaldehyde and furfural. Alkyl benzenes found in wood smoke include toluene. Oxygenated monoaromatics include guaiacol, phenol, syringol and catechol. Numerous PAHs or polycyclic aromatic hydrocarbons are found in smoke. Many trace elements are released. Reference: EPA Report Many substances on the U.S. Environmental Protection Agency’s (EPA) priority pollutant list, many suspected human carcinogens, co-carcinogens (cancer initiators or promoters), and cilia-toxic agents (poisonous to the hair- equipped cells which filter most particles out of the respira- tory tract) have been identified from wood smoke particles.

George Theodor : A very impressive list, probably the most complete listing I have ever seen . Wood smoke is however only part of the unburned components
to be found in the Unburned Effluent Discharge of Your Unit.
It is the personal opinion of your other Fellow Members ( that I share !) That Your Unit can not be made to burn at the freaky high temperatures of A Properly
built rocket mass heaterRMH, Which equals or exceeds the Efficiencies of the best ( Water Vapor) Condensing Hydrocarbon fueled furnaces.
Exactly as you have the right to post your personal experiences with the unit you have created, and speculate on the range of uses and roles it might be put to;
it it important that in fairness to the scholastic efforts of future Rocketeers who may find their way to this Thread that it is Clearly noted that your Unit as it is
presently configured- is limited in its ability to perform well with most hydrocarbon fuels !
In the spirit of fairness and remembering that we all started from zero in understanding and embracing the Science Of Rocket Heaters and always -
