LAS VEGAS--General Electric today said the next phase of its $200 million entrepreneurship challenge will focus on home energy management.

GE at the Consumer Electronics Show said that the contest, called "Ecomagination Challenge: Powering Your Home," will begin January 18 and run through to March 1.

In July, GE launched the first phase of the contest with four venture capital companies to seek out business ideas for modernizing the grid from the general public. In November, it said it will provide grants or invest directly in several power grid-related companies, covering everything from way-out ideas such as solar-powered … Read more

Some Martha's Vineyard households will soon be receiving smart appliances from General Electric as part of a pilot project, GE announced today.

It's part of mission to promote smart grid and renewable energy use on the island that has been spearheaded by The Vineyard Energy Project (VEP), a nonprofit community energy group started in West Tisbury, Mass., and the island's energy co-op, Vineyard Power.

In December 2010, VEP was granted almost $800,000 toward its goal of deploying smart grid technologies on the island, including smart appliances, via the American Recovery and Reinvestment Act of 2009.… Read more

LAS VEGAS--Several new laptop graphics cards are joining the Nvidia family today, namely the GeForce GT 555M, GeForce GT 550M, GeForce GT 540M, GeForce GT 525M, and GeForce GT 520M. These new GPUs support all the proprietary technologies that Nvidia uses to set itself apart from the competition, including Optimus, PhysX, and 3D Vision.

Optimus is notable because it allows laptops to include both integrated graphics (typically from Intel) and a discrete Nvidia graphics card, then switch between them automatically as needed. Other graphics-switching technologies typically require users to hit a manual or virtual button, or else have very simple commands, such as switching off the discrete graphics when running on battery power.

All of the new Nvidia 500 Series GPUs support Optimus, while the 550M, 500M, and 540M support 3D Vision, Nvidia's self-contained ecosystem of 3D active-shutter glasses, IR emitters, and compatible monitors and GPUs.

Nvidia is also taking advantage of this launch to lob a few attacks at sometimes partner, sometimes rival Intel. The CPU maker is aiming to reduce the need for discrete graphics cards (Nvidia's main business) with its revamped Sandy Bridge integrated graphics, which aim to be good enough so that most mainstream users (such as World of Warcraft players) won't need a discrete GPU. … Read more

Intel and GE joined forces to develop a health care alliance back in April of 2009. Today, they unveiled the name of this venture, Care Innovations, which they say has received final regulatory clearances and is now fully operational.

GE said it is the … Read more

When it comes to buses, a group of researchers say two batteries based on different technology are better than one large battery.

The Federal Transit Authority (FTA) Hybrid Transit Bus project team, which GE scientists are a part of, has built a hybrid electric bus by loading it with one high-power lithium battery and one high-energy density sodium battery, GE Global Research, GE's research arm, announced today.

Lithium batteries can provide bursts of power, but don't have much capacity. Sodium batteries, meanwhile, can store more energy, but can't provide those bursts of power necessary to propel something … Read more
