Energy from zephyrs

An item on Facebook mentioned a technique involving vertical, pipelike structures to harvest energy from vortices formed by wind blowing past them.

This reminded me of a SF story I read, back in the ‘sixties.

In that story the explorers found a planet with fields of aeolian harps

They puzzled over the purpose, until they realised that they were connected to piezo-electric crystals and were harvesting wind energy to power a long-gone civilisation.

It occurs to me that, with modern technology, it should be possible to make a sort of artificial skin with hairlike structures, converting even the slightest breeze into electricity.

It might even be possible to overlay solar cells with such a material, so that the same site could harvest both energy sources.
