List (plus three) The following are three more recent additions to the "Bright Water" dialog from two of the more active contributing, but non-Geoengineering list members. I believe all others who have already commented on this topic are list-members. Others who should be alerted will hopefully have this forwarded to them at some appropriate time .
It seems that the dialog is going well and testing might proceed even if Ken's funding might fall through (and I hope it won't) Anyone know of a plausible different source of test funding? The right team seems to be assembling.

Yes, that's absolutely right, not only does it get hottest when the water is calmest, but also light stress exacerbates temperature stress. The question is if you can power the equipment needed from the kind of output you get. The wave generator can make either AC or DC power depending on the generator used, and can have higher energy output per unit area.

I'm replying to all but will get bounced from the Geoengineering list as I'm not a member. A couple very quick comments. I developed the method for accurately predicting coral bleaching from satellite data some 22 years ago, and since then we have lost most of the coral to high temperatures (note that we have not yet lost the dead reef structures, those take longer to fall apart, but they will because the living corals that build and repair them are largely gone, and most people fail to make this critical distinction). We have also long shown that coral reefs are the most climate sensitive ecosystem and will be the first to vanish, along with the major biodiversity, fisheries, tourism, sand, and shore protection for over 100 countries. I'm certainly ready to work on testing any serious hope to save them. I've dived longer and in more places than any coral scientist, and have the world's largest underwater photo collection from the 1940s, 1950s, and 1960s (taken by my grandfather and father) so I have a pretty good idea of how they used to be pretty much everywhere. But I think Russell can confirm that the key is making microbubbles, and also finding a way to stabilize them. That may not be so easy with photovoltaics as it may require special pumps and bubbling apparatus? He knows infinitely more about this. Also a better way to power such projects may be using wave power generators. I'm working closely with a Danish group that is about to release a new generation of small, simple wave generators that can make up to a kilowatt per square meter in waves only 5-10 cm high. That will allow power to be made in most places most of the time, although it won't work in flat calm periods. However use of batteries to store night time generated energy could provide a buffer over calm periods. I'm including Per Resen Steenstrup from the wave generator group on the cc list (sorry Per, you'll need to read the thread below to see where this is coming from).
