  • Blog Post: IEEE Spectrum article on Green Energy

    In November, IEEE Spectrum ran an article titled Biofuels Aren’t Really Green . The short version is that pushing an all-biofuel solution to our current energy problems is intractable. There’s simple not enough water or space on Earth to grow all the biomass necessary. Before you jump to the conclusion...
  • Blog Post: Holiday Lights Low Concern For Northwest Power Producers

    This morning, KPLU aired a piece on the power consumption of holiday lights . The BPA says that holiday lights count for less than 1/2 of 1% of energy consumed by BPA customers. That’s really not that much. But, we can do better. According to the folks over at ENERGY STAR, compliant lights use 75% less...
  • Blog Post: Sitting in deployment – Microsoft Hohm goes live

    Other than a few minor DNS hiccups, Microsoft Hohm went live this morning. The team’s been sitting in a conference room on campus since about 5:30 this morning watching things spin up. We’re triaging other issues, but so far there have been no show-stopper bugs and no reason for any of the dev team to...

This morning we announced Microsoft Hohm . Once again I’m playing the role of architect of a Microsoft start-up. This one has...
  • Blog Post: Why are thermostats like a VCR?

    Actually, I don’t have an answer. For some reason thermostats still seem to follow a 1980s user paradigm. There are days where a simple T-50 (you know, the round thermostat) model would work tremendously better. I needed to change my thermostat settings, first to deal with the newer insulation and windows...
  • Blog Post: Temperature inversion

    Well, turns out doing a bunch of home “tightening” has some interesting effects on the climate in the house (and helped locate a few external leaks that were missed). My house is what’s called a tri-level. That is you enter on the main floor which has all the common living spaces, and can go up or down...
  • Blog Post: It’s getting warmer in Bellevue?

    I’ve been paying attention to two different things about my house for the last year or so (while I’ve gone dark). The first is that it’s unusually cold in parts of the house, the house is showing its age, and the single-pane windows always seem to be wet. The second is that it costs me an arm and a leg...
