We attended the Tuesday "Energy Day" presentation at NELHA by John Deveau, a US Navy veteran with 34 years experience in the electric utility industry who cares about technologies and policies that help the economy while preserving our planet. John's excellent 2-hour presentation covered the history that is responsible for today's problems/challenges. As John said, there is no single solution... More

If you are tired of the usual tourist attractions and have 3 hours to spend learning, take the Friday tour at the Natural Energy Lab. The tour included an informative overview of the site and its tenants, a view of the OTEC tower (Ocean Thermal Energy Conversion,) Kampachi Farms learning about their research in raising kampachi (amberjack) and grouper and...

The Natural Energy Laboratory in Hawaii does research in ocean thermal energy conversion. We listened to a talk on how the researchers are taking water out of the ocean and converting it into energy. The talk was a bit long, but the speaker was very knowledgeable. An amazing accomplishment!

Our experience on Tuesday, energy day...so much deception... We thought, that this lecture would be at least somehow technically significant by explaining energy struggles and solutions on the big island. We would have thought that, at least, during a 2 hours presentation, we would visit part of the solar powerplant. The spokesperson never told his function or role in the... More

Sarah Crawford, the Executive Director of NELHA was the presenter on our visit on February 9, 2015. She is extremely knowledgable about the various NELHA programs in Renewable Energy generation, seafood farming, deep ocean mineral water production and pharmaceutical uses of cultivated fungus farms. Also, her two hour lecture with slides and computerized videos was mesmerizing to me, as an... More

A well done presentation of the efforts to preserve the planet and the environment through sustainable aquaculture, green energy and more. Learned about Thermal Energy Conversion, the Kona Kampachi fish farm and tasted abalone at the Big Island Abalone Farm.

We were wandering around on some of the roads around the Kailua-Kona airport and saw a sign for the National Energy Laboratory and went to take a look. It was early in the afternoon but Sarah invited us in to see what information was available and what a great surprise ensued! She began talking about what NELHA and OTEC is... More

I guess this is for the guys who are dragged along to get another lecture on environmental stuff and hear how wasteful we all are. As it turns out, it's much more scientific (very boring for the kids so have them do something else) and gets almost geeky. If you have a pension for construction and/or science, you'll really enjoy... More
