The engaging presentation includes the history, purpose, current operations at HOST Park as well as information on advances in science, technology and engineering and innovative uses of sunlight and seawater combined with the research support provided by NELHA at the HOST Park campus. Learn about Hawaii’s Clean Energy Goals and how innovation at HOST Park is working toward meeting those goals on the Island of Hawaii, and Hawaii Tourism Authority’s Malama Hawaii program.
