Electrical Fragility

Preparing for Sandy’s imminent arrival, I didn’t fill up any bathtubs with water, but I did charge up all the phones, tablets, and MiFis in the house. Frankenstorm didn’t end up having a huge impact on my part of the country, and we never suffered a prolonged power outage.  My son, holed up in his dorm at what is currently a very quiet university, has gone 14 hours without power.  I suggested that it looked like he’d have an additional 2 days this week to study.  He reminded me that all of his text books are digital.

Under pressure to reduce the weight and volume of printed matter in the house, I’ve been experimenting with eBooks on my iPad.  Assured that I’ll love reading books electronically—once I get used to it—I’m still trying to figure out how to change the color of the highlighting.  I miss all those colorful Post-It tabs sticking out the sides of the pages.  Digital format seems like a great way to read things that you’ll throw away, like beach novels and magazines, but the annotation mechanisms are still weak, and the aesthetic satisfaction of a crowded bookshelf is totally missing.

Recognizing the convenience of being able to stuff multiple books and magazines, not to mention thousands of podcasts, into a single slim device, I’m ready for an upcoming multi-day trip. Even if I get delayed by weather, I should still have plenty to read. While my battery lasts.  In many ways, the digital option is a lot more convenient, but its dependent upon external power. I wonder how many people Sandy has trapped between a tablet and an empty battery.

While it is way too early to begin collecting continuity and recovery lessons from Sandy’s aftermath, the fact that only one hospital outage has been reported, suggests that a lot of emergency power systems worked very well last night.  NYU’s Langone Medical Center lost power last night (and less dramatically, Coney Island Hospital’s), and several sources today have reported that not only did the backup power fail, but also the backup to the backup.  Back in June (the other ‘storm of the century’ earlier this year, not to be confused with last year’s storm of the century), Amazon experienced a similar (failure)3 when a single incident took both utility substations offline, followed by an overheated generator, and then a failure due to the misconfiguration of the secondary backup.

Anyone who has spent significant time dealing with data centers, or any other critical system, likely has multiple war stories about failed power. Its a mundane but important topic.  Microsoft has been bemoaning the lack of researchers, developers, and engineers, but maybe what we really need are more mechanics and electricians.
