Should I till under a field and let it decay back into the soil or should I harvest everything above the ground and then process it and get every bit of use and energy out of it before returning the ashes to the field?
Either way the net energy gets returned to the cycle. I just borrowed some of it for my needs.
Dinosaurs are reptilian and theoretically they would have had the reptilian digestive systems that are far more efficient.
I think the loads of ancient horse poop is really what created the coal beds of today!
My dad has had horses all of my life. 30 full grown horses would weigh about 40,000 pounds. They eat about 200,000 pounds of hay in one 6 month period over winter. figure that much more in summer grazing.
200,000 pounds of hay turns into about 50 5000 pound truck loads of manure or about 250,000 pounds of waste product.
Put several million horses eating and pooping in one state sized area for a few thousand years and there you go, enough waste material to form a Wyoming sized coal bed 50 feet deep! And enough fart gas to warm the planet up to near fatal levels for most life!
I like that "Java Log" idea. Does it smell like coffee when it's burning? I make a couple or three pots of coffee at work every day, you might make a small log out of that, get some 300 Java logs at the end of the year... kinda makes sense.
So, you need a thing like a compactor or something? A hydraulic ram kind of an arrangement to compress the grounds into bigger pellets?
