  • Securing the Smart Home, from Toasters to Toilets

    Efforts are underway to make your smart toilet—and other connected devices—less vulnerable to hackers.

    In late December, a researcher at enterprise security company Proofpoint noticed something strange: a security gateway was logging hundreds of thousands of malicious e-mails that were clearly being sent out by over 100,000 Linux-running devices, but they weren’t PCs. Rather, they were Internet-connected consumer gadgets including routers, TVs, multimedia centers, and even a fridge.

  • Sync Your Files without Trusting the Cloud

    The company behind the Bittorrent protocol is working on software that can replicate most features of file-synching services without handing your data to cloud servers.

    The debate over how much we should trust cloud companies with our data (see “NSA Spying Is Making Us Less Safe”) was reawakened last year after revelations that the National Security Agency routinely harvests data from Internet companies including Google, Microsoft, Yahoo, and Facebook.

  • Chasing the Dream of Half-Price Gasoline from Natural Gas

    A startup called Siluria thinks it’s solved a mystery that has stymied huge oil companies for decades.

    At a pilot plant in Menlo Park, California, a technician pours white pellets into a steel tube and then taps it with a wrench to make sure they settle together. He closes the tube, and oxygen and methane—the main ingredient of natural gas—flow in. Seconds later, water and ethylene, the world’s largest commodity chemical, flow out. Another simple step converts the ethylene into gasoline.

  • CES 2014: Smart Homes Open Their Doors

    Smart home appliances could become more common thanks to efforts by major companies including Lowe’s and Staples to make gadgets compatible.

    When I interviewed Tony Fadell, the inventor of the iPod and now CEO of Nest, two years ago, he told me that he started the company, which sells smart thermostats and alarms, because existing products for taking control of your home over the Internet were clunky and appealed only to the technically minded (see “Nest’s Control Freaks”). “Home automation is for single geeky guys. It’s not for families,” he said.

  • CES 2014: Less Is More for Smart Watches and Other Wearable Gadgets

    Companies have figured out that a smart watch can’t just be functional; it has to look good, too.

    When Intel CEO Brian Krzanich unveiled a smart watch during his keynote speech at the International Consumer Electronics Show (CES) in Las Vegas on Monday, he brought his company level with Samsung and Qualcomm, both of which sell watches with sizeable color touch screens that are capable of running apps (see “Samsung’s Galaxy Gear” and “Review: Qualcomm’s Toq”).

  • New Battery Material Could Help Wind and Solar Power Go Big

    Low-cost materials could make storing hours of power from a wind farm economically feasible.

    Utilities would love to be able to store the power that wind farms generate at night—when no one wants it—and use it when demand is high during the day. But conventional battery technology is so expensive that it only makes economic sense to store a few minutes of electricity, enough to smooth out a few fluctuations from gusts of wind.
