I have posted a critical commentary on the treatment of economics and financing of the Severn Barrage in the SDC report on tidal power.  It's on my 'bacon butty' policy blog:
Severn barrage - flawed economics 

This follows an earlier posting, just prior to release of the report, that I have already circulated.  The two are go together:
Case for the Severn barrage - does it hold water? 

If you want to comment or put me a different view, please use the comment facility on the blog rather than post here.  This Yahoo! group is for posting information, not debate.
