That's Craig above, the Rainshadow machine opperator. You can see how he makes things pretty efficient.
Based on the production data we've collected, two workers, one on the excavator and one with a chainsaw, can make between 5.5 and 7.5 yards in a day.
That's Steve and Carson talking after we ran the numbers. We think we can make charcoal from the 325 tons of forest slash material produced annually in San Juan County for $200 a yard. There's potential of decreaseing the price as efficiency increases with data collection.
That's $10,520 an acre. According to the farm on Orcas, the charcoal would pay for itself by year 2. It may last for more than 4,000.
And then there's the question of nutrient density. If charcoal is holding onto and building up nutrients in soil, wouldn't this translate to increasing nutrient density in the food? Could biochar become a new "organic," a way to differentiate quality and enhance price. Don't we all want food with more in it?
