Anonymous has so far plied its trade in "hactivist" exploits. But according to the director of the National Security Agency, it might soon turn its focus to U.S. infrastructure.

According to the Wall Street Journal, citing sources, Gen. Keith Alexander has said in private meetings at the White House and elsewhere that the U.S. must keep a close eye on Anonymous' growth. He reportedly warned that if the organization continues to gain power, it might even take down a part of the U.S. power grid within the next couple of years.

GreatPoint Energy has completed a $1.25 billion deal to build the first large-scale plant for converting coal to natural gas in China, a sign of how U.S. energy technologies are often being commercialized overseas.

The Wall Street Journal on Friday reported that China Wanxiang Holdings will invest $420 million in Cambridge, Mass.-based GreatPoint Energy, the largest equity investment by a Chinese company in a venture-backed U.S. company. Wanxiang will finance construction of the plant, with the first phase to be completed by 2015, according to the Journal.

The project in China, which the company has been … Read more

CAMBRIDGE, Mass.--To those who say the world needs dramatic technology breakthroughs to get off of fossil fuels, energy guru Amory Lovins has a succinct answer: integrated design.

Lovins has been working in the trenches of energy and efficiency for more than 30 years, gaining a reputation as a radical thinker able to imagine possibilities others can't. He was here at MIT yesterday giving a presentation on his latest book, "Reinventing Fire" and speaking to entrepreneurs and investors at an event organized by Xconomy.

In a shareholder letter released in conjunction with its fourth-quarter results, Tesla gave some tantalizing details about buyer interest in the Model X electric SUV. The company received 500 reservations for the Model X, at a refundable cost of $5,000 each, after the car's unveiling on February 9.

Model X deliveries will not begin until 2014. Tesla expects to produce 10,000 to 15,000 Model X vehicles per year. Although Tesla has not announced the price of the Model X yet, it should be on par with the previously shown Model S electric sedan.

Hertz announced last week that it was testing a wireless charging station with Plugless Power on a Nissan Leaf. The new wireless charging station trial means that drivers won't get their hands dirty plugging the EV into the grid, and it's a foolproof way to make sure they recharge the battery for the next user when they drop off the car.

The test, conducted by Plugless Power manufacturer Evatran, will provide data on daily usage routines, user interfaces, and any additional functionality needed. But don't get too excited about trying out this new product. Although Hertz rents … Read more

Lemnis Lighting is taking a foot-in-the-door approach to LED lightbulbs.

The startup company today announced a new line of bulbs, priced at $4.95 and $6.95, respectively, aimed at getting consumers to try out LEDs for general lighting. The bulbs, though, have some limitations.

The Pharox Blu line comes in 200-lumen and 350-lumen versions, both of which give off less light a 40-watt incandescent bulb's 450 lumens. That means that the bulbs, which consume less than 5 watts and 8 watts, respectively, won't give off enough light for many uses, such as lighting a whole room.

Sony is looking to revolutionize the inefficient way in which we consume power.

A new concept video from the electronics giant shows how we could use power more efficiently in the year 2030 by switching to smart outlets with authentication and wireless charging on a broad scale, assuming we survive the zombie Mayan apocalypse.

The prototype power outlet, integrated with a short-range wireless FeliCa transmitter (and a new RFID over power line technology), allows the user to swipe a pay card across the faceplate and pay for energy on the spot. What makes it truly interesting is if humankind keeps progressing towards alternative energies (such as wind, solar, and biomass), then our outlets could give us options as to what source from which we obtain our power. The video description notes that with this outlet, "the user can actively control and manage power consumption on a user basis as well as on a device basis." … Read more

Pioneering solar company Energy Conversion Devices today filed for bankruptcy protection, the latest casualty in a global price war.

In a statement, the Michigan-based company said it intends to sell its solar power subsidiaries and will continue to operate during the bankruptcy and sale process.

Through its subsidiaries Uni-Solar and Solar Integrated Technologies, the company manufactures flexible silicon solar cells and develops solar projects. The solar collectors can be laid out as sheets on rooftops or integrated into roof tiles.

Energy Conversion Devices was founded in 1960 by Stanford Ovshinsky, a scientist who was also integral to developing nickel metal hydride batteries … Read more
