I post a lot about the Blue Revolution and hydrogen.  My early experience had mostly to do with: Biomass in 1962 at the Hutchinson Sugar Company on the Big Island. Then a decade later I joined the faculty of the University of Hawaii, and began a program to grow microalgae in a raceway to both produce biofuels and remediate global warming by feeding the equivalent of stack gases into the system.  Soon thereafter, I became part of the  Hawaii Geothermal Project , and in 1976 we succeeded in drilling the hottest ( 676 F ) well in the world, which went on to generate 2.8 megawatts, a baseload power source that could supply electricity for 5000 homes. All those effluents were being discarded as an environmental nuisance, so I helped create  Noi'i O Puna, or the Puna Research Center  in 1985 to assist the private sector initiate new companies in a variety of agriculture, aquaculture and tourism activities.  This was the geo-equivalent of the Natural Energy Laboratory of Hawaii Authority
