Nest CEO Fadell: Internet of things is a decade away

PARIS -- It will take 10 years before the "Internet of things" catches on widely, said Nest Labs Chief Executive Tony Fadell, whose smart-thermostat startup embodies the technology.

"People think there's this Internet of all kinds of crazy devices that are going to talk to each other. It's going to take some time," Fadell said at the LeWeb show here. "Give it five or eight years and then you'll see machines talking to machines. Then it'll be commonplace in 10 years or so."

The Internet of things is the idea … Read more

Titan steals No. 1 spot on Top500 supercomputer list

Predictions that Oak Ridge National Laboratory's Titan supercomputer had become the most powerful machine in the world have turned out to be right.

The machine, powered by Nvidia graphics processors and Advanced Micro Devices computer chips, stole the No. 1 spot on the Top500's list from another U.S. machine, Lawrence Livermore National Laboratory's Sequoia.

Sequoia, which uses processors from IBM, became the top computer in June with a performance of 16.32 petaflops a second. Titan beat that showing, sending Sequoia to second place on the list, with a result of 17.59 petaflops per second. … Read more

EnergySail promises wind-solar combo for cleaner shipping

Many shipping companies are experimenting with adding sails to cargo vessels. Here's a design in which the sails are also solar panels.

EnergySail is a concept by Japan's Eco Marine Power that harnesses and stores wind and solar power to reduce fuel costs and pollution. It would work as an additional source of power to a ship's main engines.

The devices would be fitted on anything from large bulk ore carriers to cable-laying ships, ferries, and coast guard patrol vessels, according to the company. An automatic control system would orient the sails and panels to catch the … Read more

Tech breakthrough may double smartphone life

Smartphone batteries may soon last twice as long -- if an MIT spinoff's power amplifier technology lives up to its promise.

The power amplifier is one of the most power-hungry pieces of hardware in a phone. It converts electricity into radio signals and consumes power in two basic modes: standby and output signal for sending out digital data. Such a chip wastes more than 65 percent of its energy, according to a report in the MIT Technology Review, and the only way to make it more efficient is by reducing the power used in standby. … Read more

Philips Hue smart lightbulbs glow any color

Lightbulbs. Simple, cheap, and easy to replace, right? Not anymore! Philips is dragging the humble bulb into the future with its "Hue" technology -- wirelessly controlled light orbs that give you complete control over the lighting in your house.

The Hue bulbs look like ordinary lightbulbs, and screw into light sockets as normal. Inside each bulb, however, is a wireless transmitter that communicates with a hub you plug into the back of your router.

Once connected, you can use a Web site or download an app (the iOS version is out now -- there's no sight of an Android version, though Gizmodo reports it's coming in December), then use the wonderful power of the Internet to fiddle with the lights in your home. … Read more

Titan supercomputer debuts for open scientific research

Forecasting for weather like this week's "Frankenstorm" may become a lot more accurate with the help of the Department of Energy's Titan supercomputer, a system that launched this month for open research development.

The computer, an update to the Jaguar system, is operated in Tennessee by Oak Ridge National Laboratory, part of the DOE's network of research labs. Researchers from academia, government labs, and various industries will be able to use Titan -- believed to be one of the two most powerful machines in the world -- to research things such as climate change and … Read more

Stanford Ovshinsky, 'Edison of our age,' dies at 89

Stanford R. Ovshinsky, a self-taught scientist who invented the nickel-metal hybrid battery and a new class of semiconductors, died Wednesday at age 89.

The cause of death was prostate cancer, according to his son, Harvey Ovshinsky.

Hailed in 2006 by Economist magazine as "the Edison of our age," Ovshinsky held more than 200 patents on a wide variety of pioneering products, from thin-film solar cells to hydrogen fuel cells. In the 1950s, Ovshinsky upset conventional thinking by rejecting the notion that only well-ordered crystals had useful electronic properties and suggested that so-called amorphous, or disordered, materials could be … Read more

Government-funded battery maker A123 files for bankruptcy

A123 Systems, a lithium-ion battery maker that has received hundreds of millions in government support, filed for bankruptcy protection today.

The move makes A123 the latest government-backed energy company to file for Chapter 11. Many of these companies have struggled to make money as demand slows for their products. A123 received more than $250 million in state and federal funding to help it run its operations providing batteries for electric cars and other products. But it has also faced many problems, including defective products.

A123 today said Johnson Controls will help finance the filing by buying A123's automotive business … Read more

Nest 2.0: Slimmer, sleeker thermostat smarter than ever

When the "Father of the iPod" Tony Fadell unveiled Nest, the "learning thermostat" last fall, it was likely the first time anyone had ever thought of a thermostat as sexy.

Now, less than a year after the first version of the product arrived, bringing Apple style design and user interfaces to what had traditionally been one of the most staid home appliances, Fadell's Palo Alto, Calif.-based company today announced Nest 2.0, a slimmer version of the thermostat that was built to work in more homes and brings new flexibility and features to the … Read more
