Make your preferred wind energy harvesting system, put it on or under a hydrogen balloon, raise the balloon to your altitude of choice and tether it to the ground.
The new idea, for me though I know the idea has been around, is to generate methane or hydrogen while airborne. That eliminates the need to constantly raise and lower batteries, or use a heavy electric cable, or use an unproven rope drive system. Instead you would have a supply of gas containers that you would send down, and you would periodically send extra gas containers up.
The enabling technologies for this would be a relatively light yet high capacity apparatus for making methane or hydrogen (from air, CO2, hydrogen, water, or a combination of the above), a good hydrogen balloon that doesn’t allow much hydrogen to escape, and of course your AWE harvesting system.
Windy Skies remains intrigued by the prospect of making methane with AWE without interest in reducing methane dependence in the face of Climate Change, nor comprehending the complex engineering impracticalities well known by previous discussions.
Let Windy Skies share a serious personal contribution to AWE engineering science, like an advanced AWES concept or prototype, or better treatment of essential Cosine Functions in kite physics.
This playful image on Windy Skies “silly idea” topic should not be censored from pique-
This question seems silly to me. Assuming hydrogen were an efficient means of energy storage, which it is not, why not produce said hydrogen on the ground, where the weight of the water, electrolyzer, piping, and storage container(s) don’t have to be lifted?
And if you DID make hydrogen onboard a floating station, why not send hydrogen down a lightweight tube, rather than supporting multiple storage containers at height, then worrying about how to get them up and down, transfer the hydrogen to new containers, etc.? Kids… just goes to show ya… Sheesh!
