Renewable energy/Windstalk

Windstalks are a proposed alternative to s for. Vertical wind columns are pressed against by air. This tension puts pressure on piezoelectric materials that generate electricity. This column is static, and it is meant to be relatively safe for birds and bats, unlike wind turbines.

There is a proposal to install 180 ft tall windstalks at Masdar city. The stalks are to be made of a exterior connected to a  base, and s display when the windstalk is producing power. Two electricity carrying cables are connected to alternating piezo discs that are inside each hollow windstalk.

Tidal
Could this technology be adapted to generate electricity from tidal currents?
