Natural Energy Laboratory of Hawaii Authority (NELHA)

Frommer's Review

Technology buffs should consider a visit to NELHA, where the hot tropical sun, in combination with a complex pumping system that brings 42°F (6°C) ocean water from 2,000 feet deep up to land, is used to develop innovations in agriculture, aquaculture, and ocean conservation. The interesting 1 1/2-hour tour takes in all areas of the high-tech ocean science and technology park, including the seawater delivery system, the energy-conversion process, and some of the park's more interesting tenants, from Maine lobsters to giant clams.
