Before they rejigged the site, the press release in full was available which included the notes to the editor. I remember reading that they had had people over from J-Power (Japan, experts, have similar systems. Eg: in Okinawa) as well as a Norwegian that deal in damming, a Canadian crowd that do mine sealing in British Colombia (avoid sea water seepage into surrounding land) as well another German power company. SoI said that all four of these gave the project the thumbs up. Can't remember the names of the latter three companies (and didn't save the file as I knew then I should have. D'oh!). Also SIAC did a costing and SISK came back to them confirming that their costings would be very similar to that which SIAC had estimated. As for the other people involved, your guess is as good as mine. Must dash I'm afraid though. Early rise in the morn. Poke around more and in depth off the different links on their site, I keep finding new thing out about them every couple of days when I visit again.
