<br /> <br />National Park and one at the Hilo or the Kona side in the Hele On type bus. Continue to <br />support NELHA and figure out what we want to do with our waste in the future. <br /> <br />Ms. Kelly: I got a question on the hydrogen business. Is hydrogen manufactured <br />here on the island and they’re able to store? Is it in a liquid or gas format? <br /> <br />Mr. Rolston: Yes, you can take wind or photovoltaic or geothermal to make <br />hydrogen as a gas. <br /> <br />Ms. Kelly: A gas. <br /> <br />Mr. Rolston: You use that gas in a transportation vehicle, a bus. <br /> <br />Ms. Kelly: So it’s a tank? <br /> <br />Mr. Rolston: Yes, so you have a pressurized tank in a bus. So like at Volcanoes <br />National Park, they’ll have a hydrogen bus that will use hydrogen. <br /> <br />Ms. Kelly: What is the difference in cost? <br /> <br />Mr. Rolston: It’s very high cost right now. So hydrogen is where photovoltaic <br />was in 20 or 30 years ago. So we expect that hydrogen is going to be research and <br />development project for the next 10-20 years and after 20 years then it will be cost <br />effective. We’re not going to (inaudible), hydrogen is not our big play, it’s really a <br />research and development effort. Iceland is leading in the hydrogen R&D and they’re <br />an isolated place; we feel like we have a specific island that can do hydrogen. So two <br />places in the world where really make sense are places like Iceland and here. So we <br />want to use it as a research and development economic play, not as a cost effective <br />play right away. <br /> <br />Ms. Kelly: Thank you. <br /> <br /> Mr. Rolston: You’re welcome. Next slide just shows what you can see from on <br />top of Mauna Kea at night, the glare in background is Oahu, the lighting in Oahu. The <br />next slide just describes in the title, that’s slide fourteen, High Efficiency LED Lamps to <br />darken our night skies and we hope other islands follow our lead in doing that. We’ll be <br />the first island, the first County to do a total LED lamp retro fit. So we’ll darken the skies <br />by 50% with our new LED technologies. <br /> <br /> Ms. Kelly: I got a question. <br /> <br /> Mr. Rolston: Sure <br /> <br /> Ms. Kelly: Is the astronomy center dedicated to that, those people they’re <br />participating in the cost of the changing those lamps? <br /> <br /> Mr. Rolston: They don’t participate in the cost, but we need their approval <br />because they’re very specific about how they want their dark skies to be. They’re very <br />specific about how they want their skies to look. <br /> <br />6 <br /> <br /> <br />
