Carbon negative energy source

Uses biomass to create electricity + heat + charcoal.
It is fairly standard gasification and co-generation, except that they have optimized it with microprocessor control and standard field serviceable components available almost anywhere in the world. 
This looks like the real deal - it is the first commercial carbon-negative energy technology. -- ed

World's Quietest Firebrick Blade

IIn the video, when the cut starts, there is  not much extra noise from just the sound of the motor on the Karl Dahm saw, which is also quiet. The sound was recorded by the camera standing right next to the saw. Compare with the Target saw and regular blade, that then starts up about 25 ft away. It is louder than the saw only 2ft away.

Recorded at the recent MHA HMED workshop at John McDougall's shop near Perth Ontario. Full report on the workshop coming soon.

Phenolic antioxidants in wood smoke

Jennica Kjällstrand and Göran Petersson
Dep't of Chemical Engineering, Chalmers University, Götenberg Sweden, 2002

..."The comprehensive Boise campaign estimated the lifetime lung
cancer risk due to extractable organic matter from particles (Cupitt et al., 1994). 

For the sameamount of extracted material, the risk was found to be about ten times larger for particles from mobile sources than for particles from residential wood burning. The antioxidant effects of the
methoxyphenols in the lungs are likely to explain much of this striking difference. Evidently,
the different impact on health of wood smoke particles compared to particles from other
sources should be considered when emissions from traditional small-scale wood burning are
regulated."....

Woodstacking method from Finland

Doug Hren writes:
Saw this unique way to stack and ventilate a wood pile on a recent trip to Finland.
(1) Throw it in a contained pile
(2) throw a tarp over the top that slopes away from the center
(3) make a hole in the center of the tarp with a vented roof/chimney structure.

Stack was about 12 feet tall with wooden vent structure.
