Why not test it in an area where coral reef is endangered from temperature related bleaching events? The GBR is the candidate with my vote..

If the idea has legs it will find them through protection of reef environment.

If it's not capable.. Give up.

I know it is popular to blame everything bad on a temperature increase, but bleaching of coral reefs seems like a big stretch.

The years that widespread bleaching has occurred don't align with the years with peak temperatures either in air or surface waters. There is also the coral in the red sea which is at far higher temps and not bleached.

Most large established reefs are 5000 to 10000 years old. Many estimates of sea water temps over the past 10000 years indicate periods with higher temps than the bleaching years.

This has to be due to something else. Run off of some type would be my guess.

Here are some temperature measurements over the last 100 years not far from the barrier reefs....

Here is one for waters of interest...

I can fully understand where you're coming from.. In fact I totally agree!?

I've recently watched 'Chasing Coral' on Netflix.

I'd recommend it.

There is a fair amount of information as well as disinformation I'm sure..

What surprised me was the cyclical nature of the bleaching events.

That and how quickly the effected areas would change from live to dead.

Of course the show was heavy on the gloom pedal. It didn't focus on recovery or point at new growth..

My post was an attempt to point this seemingly absurd technology at an area where they are currently bitching about small water temperature fluctuations.

I was watching a show where divers were in icy Alaskan waters that were filled with vibrantl

I'd say more but I have to go for now.

Global warming oops climate change is a hoax propagated by the people making money from it.

Professor Dr. Friedrich Karl Ewert is a retired geologist and data computation expert. He has painstakingly examined and tabulated all NASA GISS’s temperature data series, taken from 1153 stations and going back to 1881. His conclusion: that if you look at the raw data, as opposed to NASA’s revisions, you’ll find that since 1940 the planet has been cooling, not warming.

From the publicly available data, Ewert made an unbelievable discovery: Between the years 2010 and 2012 the data measured since 1881 were altered so that they showed a significant warming, especially after 1950. […] A comparison of the data from 2010 with the data of 2012 shows that NASA-GISS had altered its own datasets so that especially after WWII a clear warming appears – although it never existed.

But the activist scientists at NASA GISS – initially led by James Hansen , later by Gavin Schmidt – wanted the records they are in charge of maintaining to show warming not cooling, so they began systematically adjusting the data for various spurious reasons using ten different methods.
