Yup, Slater's wave is DOA because of this:
> He chortled, but he did not stop peering across the water, assessing the waves and the state of the pool during the three minutes that it was left to settle between waves.
1 wave every 3 minutes will never be economically feasible. They're currently charging $10,000 per hour, whereas BSR charges $60 per hour and you get several times as many waves per session.
American Wave Machines' system can already pump out a full set of waves every 10 seconds AND they can change the shape with the push of a button. Beginner, intermediate, advanced, left, right, air sections, barrels, they do it all.
Slater's wave will never be anything more than a toy for himself and a few of his close friends. Every surfer I know said the surf ranch competition was the most boring thing they ever watched.
