Been fielding a few questions about vog lately:http://www.terrawatthome.com/news/2018/05/16/what-you-can-do-about-vog--------------------------------------"Vog is a form of air pollution that results when sulfur dioxide (SO2) and other gases and particles emitted by an erupting volcano react with oxygen and moisture in the presence of sunlight.

The Math on Solar Hot Water in Hawaii

I got a question from a PV salesperson about SHW, went to energy code trainings and SHW came up, and have been reminded a lot lately that SHW is a viable option. I had to write it down to organize it before it all went away. Here in Hawaii, passive solar systems are prevalent because we don't have to worry about freezing so much. We also have $0.34/kWh electricity on the Big Island.link to blog:…See More

"Yes, all of that.  The next part (stay tuned for part 2) will be about my hunt for a decent design temp.  I found a Weather Underground station very near me, and in looking at it, I'm in the 52-55 range. I do like it when I get to…"
