NELHA's Hawaii Ocean Science Technology Park
Just south of Kona International Airport, a big building with a large photovoltaic (solar) panel installation resembles a top-secret military station, but it's actually the site of the Natural Energy Lab of Hawaii Authority's (NELHA) Hawaii Ocean Science Technology (HOST) Park. Here, scientists, researchers, and entrepreneurs make use of a cold, deep-sea pipeline to develop and market everything from desalinated, mineral-rich drinking water and super-nutritious algae products to energy-efficient air-conditioning systems to environmentally friendly aquaculture techniques. Seahorses, abalone, kampachi (a type of yellowtail), Dungeness crab, and Maine lobsters are raised here, too. Farm tours are available directly through tenants Big Island Abalone, Ocean Rider Sea Horse Farm, and Sea Salts of Hawaii.
