Opps. Interuptis there. Surgery results consult for the wife. Getting old is not for the feint of heart.
Just east of us toward the Cascades crest the elevation rises dramatically. There annual precipitation is between us and the coastal rainforests. In the true mountains more measured in feet’s of snow fall; then the settled down snow pack.
Woodgasing factors to all of this.
The challenge has been to be able to make systems able to fuel with 40% to 60% by weight moisture, low density conifer woods.
Woodstoveing with 20% dried down wood I get 80% efficiency heat into the space heated areas. Have learned to take this up to 60% moisture woods as a fall-back, if/when needs-must. Only ~20% efficiency heating space having to wood energy commit to handling all of that excessive moisture. Still can heat. Just have to chop a lot more wood. THIS IS THE 150 years, generations living here in the wet traditional, have-many-kids-to-work-sweat-the-wood, way. Proven. Creosotes up chimney’s badly unless burnt, high flow, hot.
Engineered designed and built wood gasifier systems very solid at 70% efficiency IF using 10-15% moisture wood fuel inputs. With gasifier total system heat recycling this can be pushed up to ~30% moisture wood-in before too much efficiency conversion dropping.
How to handle the wetter yet woods without the sun: and/or sub-freezing drying days?
Put the IC engines and generators head “waste” to work - not blown away wasted! Predrying/dehumidfy down the wet wood to 20-30% Before going into the gasifier hopper.
Not a recovery system able to do with vehicle mobile systems. The vehicle shed-off heats are too far away , and spread out. The wet wood to be dried additional weight loading on the vehicle gross weight too punishing leaving too little net capacity for usable cargo.
True green 40% wet ; and sat outside, then 60% weight wet conifer wood as an input then take-out charcoal making is a fantasy.
All conifer char will be used up drying down this excessive raw harvested 40% to 60% by weight moisture wood to gasifier useable.
Doable. Proven now.
