Highly recommended. Educational and also fun.

Very interesting research going on here. Tour the 6-12 school. Those kids are smart!! They are doing tons of experiments. They have aquariums, an octopus, sharks, robots, etc. Lottery to get in. Hawaiian monk seal rehab center. learn about how they can cool a building with water and air currents. Learn about new research in sustainable fish farming, octopus farming, sea horse farming. Generating electricity from using the cold water and surface water temperature differential (not that efficient, but it is really for testing new heat exchanger designs and the clean cold water pumped from the deep has several other uses. They also have wine grapes growing 3 crop cycles per year instead of one by using the cold water from the deep and condensation. They are several other research facilities in this area but it is all very interesting and could be a breakthrough job market in the future.

We loved this. The tour was incredibly interesting. NELHA is doing some amazing work. Visiting the charter school was very cool and made us want to go back to school (one of that type of course..) Definitely a very cool activity to do in Kona.

This tour is fun, enlightening, inspirational, and did I mention, fun! Four of us enjoyed visiting the NELHA facility, learning about the use of surface warm and deep cold ocean water to create thermal energy. Many smaller upstart businesses utilize the ocean waters to work on various sustainable fishing ideas and agricultural issues. Fascinating to see where the future may be going.

This was a great opportunity to meet with the future. Most interesting cutting edge technology with the use of deep sea water. The ability to produce power with nearly zero carbon footprint. Farming seafood in the open ocean and many more ideas are fostered in this facility.

There is a different tour every day here and it is well worth a visit. There are 40 organizations on the site under the umbrella of NELHA . They are all research oriented and working toward sustainability and conservation. Part of our tour was to go to the Marine Mammal Center where they are working to conserve endangered monk seals, and to visit an octopus farm. We then visited OTEC, which makes electricity by using warm water from the top of the ocean and cold water from the bottom. It's a demo at this point but we were fascinated by it and by all the work going on here.
