Some good info. I am just across the border in NB so similar weather. I wish I could grow something on the land to make a few dollars on the side. Heating with what ever I grown sounds like its not feasible.
I was not saying that at all, to me the numbers looked favorable.
If you do not already have a pellet stove, you could buy a flex-fuel stove and perhaps burn 100% corn. If that is the case, then you might be able to grow your own corn. I cannot remember the numbers off the top of my head, but it was like 1 acre of corn equated to 3 ton of corn kernels. There is no free lunch, a person would have to buy fertilizer, some seed, etc to get it to grow, but time wise, what does it matter? If you are putting in a garden, just make it bigger and grow an acre or two of corn. It would not be that much more time.
As for harvesting, corn is nothing like making wood pellets. There are lots of videos on youtube on how to make homemade machines that strip the cob. I would just wait until frost kills the corn and gets some serious dry-down, then harvest the cobs and run them through a chain beater. In the end you would have an acre or two tied up in corn, but it is no different then the people that have a few acres of forest to have enough firewood to heat their home. And you would be producing far more then a few hundred pounds of wood pellets with $10,000 worth of pellet-making equipment.
As I said, the numbers looked pretty good for me, and I was just calculating on a 1/3 mix. FOR ME...it just makes more sense for me to cut 9 cords of tree length firewood and sell it, and in one days time, get enough money to buy 100% of my wood pellets that I need to heat my home. If I did not have a free wood pellet stove, I would have bought a coal stove, and did the same firewood-sell-for-coal-thing. But again, that is me, your situation would be/may be different.
I do not think making wood pellets would work. It would be a tall order to get the sawdust, run it through a hammer mill, then run it through a pellet-maker, all at 600 pounds of pellets per ton, get it down to 6% moisture content...all for less than $230 per ton.That is a lot of time spent doing it, and on the equipment.
But corn...is already that size, you just need to get it off the cob. The same could be said for sunflowers too. They grow well here, and maybe where you live...I do not know. They only yield 1 ton to the acre, but I think the cool-factor would be nice: a few acres of beautiful sunflowers in the summer, knowing they will heat your home all winter.
