Wesley Johnson : I am glad that you are a fellow member here at Permies.com, and are willing to look outside ''the box'' to locate additional sources/methodologies of Energy use.
There are several reasons why bio-mass materials like bamboo and Hemp are good candidates for use as bio-fuels besides their rapid Growth !
However any harvesting plan that does not return a significant % of the original plants Organic materials to the soil is not sustainable, and needs to be addressed at this end of the
process not by ''kicking that can down the road'' - to be solved latter by other/future persons. Failure of the Bio-fuel people to disclose their unwillingness to address this issue
makes their grafts and charts nearly useless !
At the extreme end of the '' fastest growers'' would be algae grown in the processed effluent streams of Waste Heat and CO2 supplementation; this closed process needs only the
addition of ''Free Solar", to create large amounts of Algae, which can then be used as many forms of feed-stock in a sustainable manner - Unfortunately a few key roadblocks have
kept this effort from being commercial for 20 + years !
Row-croping fast growing Tree species ( Willow, Poplar, Black Locust ) can be done in a manner very similar to the other Solar Collectors you mentioned placing in farmers fields.
A little research on Coppicing and Pollard-ing these trees will help you understand there 3 yr cycle harvesting rate
Finally, We need to avoid the decades long trap of Shipping "Wood Pellets'' to Europe, while importing more from them! Again this is an all to common practice that makes any
''real world accounting'' nearly impossible !
For the Good of the Craft ! Big AL
