Ocean Thermal Energy Conversion (OTEC) technology development offers insights for water-producing greenhouse proponents
This interesting article in EOS, published by the American Geophysical Union (AGU), has insights about the development and deployment of OTEC that are likely to apply also to water-producing greenhouse technologies.
The January 2021 issue of the Caribbean Agro-climatic Bulletin of the CariSAM presented these interesting maps. Highlights: (1) Dry spells are probable for The Bahamas, Cayman Islands, and Cuba. (2) Long-term drought may occur in Grand Cayman and St. Kitts. For details, visit https://rcc.cimh.edu.bb/carisam-bulletin-vol-4-issue-8-january-2021/
A recent article about Seawater Air-Conditioning (SWAC) contains knowledge applicable to the design of the WaterProducer-Greenhouse™.

The WaterProducer-Greenhouse™ design is intended for tropical small islands, many of which are small island developing states. Here is a link to the official United Nations list of small island developing states.
Because the WaterProducer Greenhouse Project is an appropriate technology for small island developing states, this new series by DEVEX is quite relevant for visitors to this site.

A recent online article by Dr. Fernando Pérez Monteagudo (Professor at the Centre for Hydraulic Research, Havana, Cuba) in Water & Wastewater International explained how desalinated water supplements the rainwater fed drinking-water system on Grand Turk.
Sustainability must be the goal of water resources management in small islands, and Grand Turk, the capital of Turks and Caicos Islands, is carefully preserving its complex water supply system fed mainly by rainwater and supplemented by desalination. Read more...
I have the privilege of being accepted as one of the presenters during the Technical Sessions at the 23rd Annual Caribbean Water and Wastewater Association (CWWA) Conference and Exhibition scheduled for October 6-10, 2014 at Atlantis Resorts on Paradise Island, Bahamas. Here is the Abstract of my paper:
Regional droughts in the Caribbean are common. Water managers seeking solutions to water scarcity are often unfamiliar with the option of using water-from-air technology. Maps of the specific humidity composite mean for Junes and Decembers during the ten-year period 2004–2013 quantify the water-from-air resource demonstrating it is suitable for operation of water-from-air systems in Caribbean countries. Quantitative investigations by the author found droughts and long-term climate change do not appear to affect the magnitude of the Caribbean region’s water-from-air resource. Case studies include one for a proposed water-from-air commercial greenhouse on Grand Turk. Another case is about the experience of commissioning a 2500 L/d water-from-air machine in Belize City. Lessons learned from the case studies are outlined.
I discovered that Turks and Caicos Weekly News Online featured an article (August 12, 2011) about our project participant Nicholas Turner.
The opening paragraphs from the article.
TCI’S long neglected agricultural sector is in for a major boost thanks to a forthcoming national training centre to educate a new generation of farmers.
North Caicos’ listless government farm is to be transformed into a venue to research the best way to grow crops – with the emphasis on organic produce.
Aspiring farmers will be given plots of land on the vast 160-acre site for a peppercorn rent. They will then receive training from farm staff on the best techniques on everything from irrigation to fertiliser.
It’s just part of plans unveiled by new agriculture director Nicholas Turner who hopes the Islands will eventually yield enough fruit, veg, dairy products and meat, to feed the entire nation.
