This Hidden Ocean Tech Could Power the World | The Ocean’s $Trillion Energy Secret

The entire global tidal stream industry has produced less electricity than a single offshore wind farm generates in ten days. After two decades of development and hundreds of millions in investment, roughly 35 MW of tidal stream capacity has been installed worldwide — total. Two modern offshore wind turbines exceed the capacity of the world's largest tidal array. Yet the underlying physics is compelling, the engineering is proven, and the technology may be exactly where offshore wind was 25 years ago. This report delivers the full engineering breakdown: how the turbines work, what they've actually produced, what they cost, who's gone bankrupt, and whether the numbers add up
