$this->bbcode_second_pass_quote('yesplease', 'T')hat depends on the trees you have on your land. If you're growing trees in a high yield area, then I think you could get a couple tons/acre/year, which would good for quite a bit of travel, but your range would blow due to the amount of wood needed. Depending on the type of wood on your property the yield may not get you any more than a few hundred or thousand miles per year if you just collect dead material. To put that into perspective just two acres of rapeseed would provide enough fuel to travel ten thousand miles in a small diesel car.
Far be it from me to tell ya what to do w/ your own land, but if I were in your shoes I'd look for a less labor intensive system. Having to deal w/ all 50 acres just to drive a fraction of the distance I would having to deal w/ a couple acres isn't something I'd go for. Besides, you could probably see some income selling the extra wood to others in a post apocalyptic zombie wonderland.
I'm still also confused about why you mentioned price. Were you going to charge yourself for your own cords of wood? It seems like something to do when price isn't an option, and ya don't mind lots of labor compared to alternatives, but not something for most.
Most of the price of a cord of wood is the labor to cut it and the transportation to where it is needed. Even if you own the trees someone, yourself or someone you hired has to do the work. To think that any piece of wood is free when you put it into the stove or the gassafier is wrong and the current market price is a fair estimate of the time and effort required to obtain it at the point of use. I wont charge myself for my standing wood but my back muscles will charge me dearly for every cord.
If you consider the process of switching to an alternate fuel it can be helpful to break it down into phases. Phase one growing or acquiring the fuel feed stock. Phase two refining the feed stock into useable fuel, And phase three modifying the engine to run on the new fuel.
Phase one gets ruled by what you can actually grow to a useful stage on your land. I'm not going to be growing any palm oil in VT.
With biodiesel phase one and two are hard but little needs to be done in phase three. With 100% ethanol you have to build a very good still in phase two and modify your engine/carburation unless you own one of the newer dual fuel vehicles coming out.
With wood gas I own the feed stock and have the tools and knowhow to process it to the point of use. Phase three is considerable though as it looks like you are carrying your refinery on the vehicle along with some carburation modifications.
I haven't begun to do a complete comparison analysis and have no opinion which will be better for me on my location. This was just in the news and local and I thought it would be of interest to those here. Got to wonder if the guy is lurking here at PO. It sounds like he spends some time at the keyboard.
