DP>Well, to be honest... I don't know. I am not sure I followed your idea
DP>completely. I would like to hear about the project if you get it rolling
DP>though. BTW don't put a bolt thru the tree. Secure it arround the tree.

The basic idea is that trees oscillate in the wind and this oscillatory motion
can be harnessed. By using three or more cables, you can assure that what ever
direction the tree moves, it is away from one or more of your ground-based
pulleys, providing tension in the corresponding cables. Once you have
intermittent tension in a cable, there are many ways to make that tension work
for you.

My ASCII art capabilities are not up to the wonders I've seen on the Internet,
but I'll try to draw you a picture. The "O" is the collar mounted about 2/3 the
way up a large tree. There are three cables running from the collar to pulleys
(the "+"s) firmly attached to the ground. From these pulleys, the cables take
separate routes to a common transmission. Each cable is attached with an
individual spring & ratchet reel ("="). Tension on any one of these cables will
cause that cable to unwind and turn the axle ("|"). When this tension is
released, a spring rewinds the cable without turning the axle. Since any motion
of the tree which produces slack in one cable will produce tension in another,
the axle will always be in motion, albeit unsteady. Now that we have a turning
axle, we can put most anything we want at "X" to use the energy so harnessed.

Hope this did more good than harm...

Almost all you see in marine supply stores is either plastic coated steel wire
rope or stainless wire rope.  You will want to check with a logging or rigging
or wire rope store.  Possibly whoever sells farm equipment in your area can find
some for you.  Wire-rope lube should be available from the same source.
