Thank you very much for the link. Such a machine below is what we 
would find most useful because our primary product is live stakes for 
restoration. Also stacking for air drying as fuel in a farm scale 
gasifier would be facilitated as bundles.

The latter for us is strictly a study topic for us and our scale of 
operation (just now scaling up to 5 acres) means that machine harvest 
is beyond us. Also my study of coppiced willow as an on farm energy 
source is as a substitute for conventional fuels and electricity when 
(if!) they become too expensive to utilize and deindustrialization 
becomes a trend to reckon with. There are places though, as in the 
remote communities of Alaska where this now the case. I am thinking 
small community scale biomass energy will advance in this venue where 
employment can be made as substitute for impossibly priced fuels.

Along this line I am conducting research on the use of charcoal as a 
soil conditioner and soil nutrition management tool. Again the reason 
I read the bioenergy, gasification and terrapreta lists and have 
struck up informative acquaintances with Tom Miles, John Flottvik and 
others.

It would be most fascinating to attend, World Bioenergy 2008 
Jönköping 27-29 May , but this year I am trecking to Brazil to study 
terrapreta on my own. Perhaps such a conference would be a likely 
place to present my research at some time in the future

Hi
I just read your e-mail to the gasification list about cultivating 
willow for energy. I think a good source for information and 
experience might be the Swedish Bioenergiassociation. The development 
of willow cultivation on farmland started here in the 1980ies and 
there are quite a few people growing willow and using special 
machinery for harvesting and chipping in the same operation. However 
a different way is to cut the willow with a machine that makes 
bundles that are easier to transport and to store. The machines have 
been developed from sugar cane harvesting machinery. If you contact 
the association you can probably get more information. Their homepage 
is www.svebio.se and if you click on the English flag you will get 
information in English. Although many farmers are growing Salix here 
and there the most popular and cheapest biofuel (not considering 
waste) is branches and treetops leftovers from the cutting of forest 
for timber and pulp.
