Pelamis appoints administrators, page-6

"There is also a lack of design convergence in wave energy with many different concepts in development, while tidal appears to be converging on a front-runner design."

Unlike tidal energy, the convergence of wave energy will be more difficult.  None so far has come up with a design that will adapt to both near shore shallow water as well as to offshore deep water.  CETO 6 may bring CWE to the forefront as a technology that will be able to adapt to both environments.

Meanwhile the Scots are doing their best to save the industry following the news on Pelamis.
