The Internet Gets Physical

[Commentary] Internet is growing up and lifting its gaze to the wider world. To be sure, the economy of Internet self-gratification is thriving. Web start-ups for the consumer market still sprout at a torrid pace. And young corporate stars seeking to cash in for billions by selling shares to the public are consumer services — the online game company Zynga last week, and the social network giant Facebook, whose stock offering is scheduled for next year.

As this is happening, though, the protean Internet technologies of computing and communications are rapidly spreading beyond the lucrative consumer bailiwick. Low-cost sensors, clever software and advancing computer firepower are opening the door to new uses in energy conservation, transportation, health care and food distribution. The consumer Internet can be seen as the warm-up act for these technologies. The concept has been around for years, sometimes called the Internet of Things or the Industrial Internet. Yet it takes time for the economics and engineering to catch up with the predictions. And that moment is upon us.
