Smart Lights

Several days ago my son, Thomas, and I were grocery shopping at a Target store in northern Virginia.  We noticed that the lights in the freezers in the frozen-food section were off – but then turned on the moment a customer walked close to one of the freezers.

The lights-triggered-by-motion-detectors save Target money (by keeping its electricity bill down); they save consumers money (because they are a source of cost-saving that enables Target to further lower its prices as it competes with the likes of Wal-Mart and Safeway); and, of course, these motion-detector-triggered freezer lights reduce the demand for electricity generation – cleaned by capitalism.

Thomas used his iPhone to take this very short video of me triggering the freezer lights.
