Anyone thought about, or come across, what I like to think of as an original idea that probably isn't!

A "Treebine" ... Cable from a "Dynamo" on the ground to top of a wavy branch.

(If you've seen a pole lathe in action you'll get this straight away.)

Lots of variables I'm sure, and only just beginning to think about it, so all observations welcome (except "can't see it working" which never got anything built)

A mate of mine, who is a bit of a nutter when it comes to this sort of thing, has loads of free time and no visible means of support, had a lashed up generator operating from compressed air (akin to Figure 4 in your link). He used a tree movement to operate a link to weight on a ram cylinder that charged a receiver - from there he used the resultant "compressed" air to operate a generator - this was very small scale but i can vouch that it did produce electricity at a useable voltage (albeit in small bursts).

I think the inspiration cam from "wave snake" type thinking used for capturing wave movement.

I guess it has some potential, but chopping down the tree to provide biomass and erecting a small VAWT turbine on a clear site might be easier

... just realised where this might have crept in to my sub-conscious ...... "ET"s "phone" ...?
