SunRun offers Home Solar in Hawaii

SunRunSunRun announced today that it will offer its solar power service in Hawaii to residential customers. SunRun will offer homeowners rooftop solar systems for as little at $0 down. The homeowner then pays SunRun for monthly solar electricity. The estimated monthly savings is up to 15% less than current electric utility rates. SunRun owns, monitors, insures and maintains the solar panels at no additional cost. In the States that SunRun offers this service (which include Arizona, California, Colorado, Massachusetts, New Jersey and Pennsylvania), SunRun teams up with local solar system installers. In Hawaii, they've teamed up with two major solar integrators, Sunetric and RevoluSun. This supports the local economy with jobs and opportunities. According to Alex Tiller, CEO of Sunetric,
This program opens the floodgates for every homeowner who wants to switch to solar. Thanks to SunRun, Hawaii will reduce its dependence on fossil fuels while taking control of its power bills. Additionally, Sunetric will be able to grow its team and stimulate much-needed job growth in the Islands.
In researching this announcement. I found this video of Lynn Jurich, President and co-founder of SunRun speaking on a panel at the Scientific American Rountable: Meet the Future. In section 7, Lynn describes the challenge of solar power adoption and SunRun's solution. It is an informative overview of what they have in mind for homeowners in Hawaii. If you find this interesting and want to find out more, tune in on Wednesday, Sept. 22 at 5:00pm to Bytemarks Cafe on 89.3FM KIPO - Hawaii Public Radio. We will have Lynn Jurich on the show by phone. Joining her in the studio will be Mark Duda of RevoluSun and Alex Tiller from Sunetric. If you have any questions on how this "Power Purchase Agreement" works this will be a perfect time to call in  (808) 941-3689.

Fuel Mandates

In preparation for this week's Bytemarks Cafe, where we talk to Stevie Whalen from the Hawaii Agriculture Research Center and Dave Waller from Hawaiian Electric about biofuels, I dug up this presentation done by Maurice Kaya back in 2002, while he was the State's Chief Technology Officer. In it you will find background information about the State's fuel mandates on the use of ethanol. As it turns out, the use of 10% ethanol in gasoline is mandated by law. This was supposed to coincide with the production of biofuels and the extraction of ethanol in the state. This did not happen as planned at the ethanol is now shipped in from out of state. Tune into KIPO 89.3FM on Wed 3/10 at 5pm and find out "the rest of the story." Ethanol Fuel for Hawaii State Policy, Incentives, and Mandate -

Humdinger Wind

After our episode of Bytemarks Cafe on 12/3/08, I realized the question to how the Windbelt converted wind energy to electrical energy was never really answered with any clarity. Several callers and listeners responded that we seemed to evade the question. I think it was less a matter of evading and more one of not knowing. Even our guest, Jerry Chun would admit to that. So, I did a little research and found this out. The belt is fastened firmly to one side of the aperture. At the other end it is attached to magnets that move due to the aerolastic flutter, between two copper induction coils. This action will cause an electric current to flow in the coils. The current is then conditioned with additional circuitry to direct current (DC) much like a battery. It can then be used to power a lamp or a radio. Here is an informative video of Shawn Frayne explaining how the Windbelt works. The Pure Energy Systems website also featured a section on How the Humdinger Windbelt works. The inventor, Shawn Frayne helped to explain the background and operation of the Windbelt. Partner, Jerry Chun provided me with this micro-windbelt-executive-summary (.pdf) for the Micro Windbelt that you might find interesting. Thanks for all the feedback and comments. I hope this was helpful. It certainly made for an engaging show topic.
