Good afternoon Northern Utah...haven't been there since the 60's....
We may be on opposite ends of the country so to speak, but the TT load of common sense that tipped over in your neighborhood was certainly medicinal. I've still got all my fingers and toes....not as straight as they used to be, walk hunched over....limp a little,......... but unless I could mechanically do wood, it would be the last choice on a list of 999 other options.
The 10,000,000 BTU bio-energy boiler down the road a piece, is a testament to not reinventing the wheel. Throw enough money out there, somebody will grab it. IF you are the guy's who maintains 'some engineering dream', you sure have job security re-engineering the "masterpiece" to try to made it work reliably. Yes, I'm down there a great deal because I'm interested in learning and helping out. Richard needs to make a new WTF...were they thinking (WTFWTT) smile!

Borrowed from the AHS Website: You do the math...before you sell the Mark 11. I've burned over 1000 tons in 37 years....as Cuba Goodings said to Tom Cruise: 'SHOW ME THE MONEY!'
Fuel Source Alternatives Comparison to Coal
The table below compares the cost of historical fuel sources. Alternative energy sources are only included indirectly under the assumption that alternative energy sources such as wind and solar power are typically used via the electricity that they are configured to produce. Note that the price of electricity can vary widely.
How to use this chart…
Check the price of Anthracite coal in your area. Find that price in the Anthracite Coal column below. In the row corresponding to that coal price, you will find the prices of other heating fuels necessary to match the BTU/h output to price ratio for coal. If coal costs $130 per ton, to get the same amount of energy (BTU/h) for the same cost, heating oil would have to cost $0.65 per gallon and propane would have to be $0.42 per gallon. Information from US Dept. of Energy.

The following is a listing of heating value per unit for common heating fuels. The column of equivalent units is based around the heating value of 1 ton of wood chips. For example, to get the same heating value BTU's) as a ton of wood chips, you would need to burn 54.9 gallons of #2 fuel oil.

Softwood 15 million BTU/cord 0.51 cords
Hardwood 24 million BTU/cord 0.32 cords
Green Sawdust 10 million BTU/cord 0.76 tons
