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.

The Natural Energy Lab Hawaii Authority is doing tons of great work in research, green technologies, conservation, husbandry, and natural products from the sea. Friends of NELHA have a couple of different tours to showcase some of this work, as well as the really cool innovations in their own buildings for cooling and moving toward Hawaii's energy independence. It was almost too much and too fast to absorb but I was hooked. Your tour cost pays for the visitor center staff of one and also is shared with the non-profits doing their work out there. We took the Ocean Conservation tour and got to visit OTEC, the Monk Seal Rehab center, and the Kanaloa Octopus farm (which we had already visited independently but were happy to see again). Come support the great, green work being done out here and get fired up about conservation and science! Not recommended for babies or children whose scientific vocabulary is limited to poking things with sticks.
We were unable to see much at the monk seal rehab place because they had just been tented for termites, which was disappointing, but we learned a lot about the seals and the work they do and how they find and help these incredibly rare creatures. You will not get to see seals and interact with them anyway because they are protecting them from human interaction as much as possible so as to be able to rerelease them into the wild.
The Kanaloa Octopus farm I reviewed on its own but it is wonderful to get to meet and interact with the different octopus (all the same species, the day octopus) and learn about the work they are doing trying to raise them.
The Friends of NELHA building itself and OTEC (ocean transfer energy) were interesting from an engineering perspective and the amazing sea water energy transfer that was cooling the buildings. Highly recommend for conservationists, scientists, and kids interested in saving the planet! Also recommend for people who don't understand why we need to save the planet.
Candy was our guide and she is so passionate about all the work being done in the Hawaii Ocean Science and Technology Park. All five of us on the tour were inspired to support the work in whatever ways we could.

We had a talk and slide show about renewable energy where description of the research being done was explained. One of the projects is to produce electricity by using the temperature difference between deep cold seawater and surface seawater. They bring cold water from 3000’ down (75 degrees) and warmer surface water at 80’ down(30 deg). One engineering company can produce 100 KWH of electricity (can provide 5-10 houses); more research is needed to increase production. There are many private businesses in the compound that use the deep seawater. We also visited an Octopus Farm where they are trying to find how to farm octopus, also toured Big Island Abalone Farm—the only abalone farm in Hawaii—very interesting. We took the Wed./Fri. tour called Sustainable Aquaculture. There were only four of us so we did not do the Kampachi Farms tour (8 people needed for this); instead we did the Octopus farm tour. Note that you can do the Abalone Tour separately on your own , M, W, F at 12:15 pm.
