As the wind blew and tossed about the top of the tree, the lines would pull through mechanical gears that would generate electricity. When the wind let off, or blew in another direction, springs would automatically retract the lines...think of it as a big recoil, like starting a small gasoline engine. Because the lines were attached in multiple directions, no matter which way the wind came, power would be generated.
About the only major cost would be configuring the recoils and attaching them to a generator.
I think there is some potential energy to be gleaned from a 80 foot tree with its boughs catching a fair square footage of wind. Add in the leverage of 80 feet and that is some serious torque.

A storage system that is low power (building up it's energy slowly over a longer time) is likely best suited to a load that uses low power (depleting it's energy slowly). It's possible to go counter to this - deplete the storage quickly, re-build very slowly - but often this is where finding a practical application of non-battery storage systems runs into problems.
Someday I'd like to go back and take a look at pre-grid farming tech. At that time, the wind/battery 24V system seemed to be the winning solution. I'm not aware of what it's technological competitors were at that time.

They run a lot of motors and machinery directly off of 180V solar- no batteries, no inverters, no charge controllers I think.
Then for low power loads they use a few Ni-Fe batteries.
I'm really not doing justice to what they seem to be doing IMO. I didn't know so much could be done directly with 180V power. Also, their thermal storage systems seem unique.

I'm not sure what you're referring to as far as the solar barbecue. I use the Rand solar oven (like $70 or so on Amazon or eBay). The latest one is working quite well. I've got YouTube videos up (as do a lot of other people now).
