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 word is a portmanteau of the words ‘volcanic,’ ‘smog,’ and ‘fog’…the Kilauea volcano, on the Island of Hawaiʻi (aka “The Big Island”), has been erupting continuously since January 3, 1983…Kilauea emits 2,000–4,000 tons of SO2 every day.” (Thank you, Wikipedia.)

The Math On Solar Hot Water In Hawaii

I see the ads. Go solar! Save up to 40%! I have friends. They say it’s cheap! It’s the most energy you can get from the sun! The government says it’s a good idea. Such a good idea that since 2010, Hawaii has REQUIRED a solar hot water (SHW) system on every new home built. (There is an exception for on-demand water heaters but that’s a topic for another day.)

My Award-Winning Feijoada Recipe

I entered this into a chili cook-off and won third place. It’s not even chili, but it won. It’s that good. I can’t really take credit for this recipe, because it’s the national dish of Brazil. For a reason.

Heating Houses in Hawaii (PT. 1)

I live on the wet side of Waimea, north of Mauna Kea. You know what “mauna kea” means, right? It means “white mountain.” You know why it’s white, right? Because it snows sometimes. Today’s news:

Blake is a motivated action-oriented wiz kid with just a touch of wise ass.

Blake performed an energy audit for my in-laws as they evaluated whether to continue aging in their country home of 25 years. He could easily have sold them services they didn’t need. Instead, he pointed out immediate health-and-safety concerns that they could easily address on their own with a few … Read More

Joel Frank, Contractor

I’ve known Blake for more than 30 years. I hate Blake. Blake is who I would be if I were smarter, better looking, and a hell of a lot more efficient. But I’m not and his silly business is too far away for me to hire him so I’m stuck … Read More

We worked with Blake as a consultant, providing third party advice on the type of boiler we should install based on our budget, climate, and desire for long term reliability. He was generous and patient with his time, helping us to think through our options and chose the quote from … Read More


The great room in the middle of our house has an 18-foot open-beam ceiling that has always collected more heat than expected, despite the excellent ventilation the room receives. Before consulting with Terrawatt, we installed an attic fan to pull heat from the upper great room into the attic, which … Read More
