Credit card-size cooler from GE is slim, silent

General Electric has developed an ultraslim cooling solution that could be used in laptops and tablets in the near future.

The cooler uses what GE calls dual piezoelectric cooling jets (DCJ for short). Unlike fan-based versions, which utilize spinning blades, the DCJ implementation is akin to mini bellows that suck in cool air and push out warm air. … Read more

Lots of little 'lectrics at the LA Auto Show (roundup)

Take a look around the 2012 LA Auto Show and you'll see quite a few compact, fully-electric vehicles. Having spent much time creeping along at 20 mph on Los Angeles' gridlocked highways and stopping-and-going on its crowded streets this week, I can think of no better city to get excited about EVs.

We've rounded up the biggest players in this year's small EV class, many of which are currently available to consumers or will be sometime in 2013.

Chevrolet Spark EV

Chevrolet follows up its Volt with the smaller, simpler Spark EV. Based on the smallest model … Read more

GE wants to plug in the 'Industrial Internet'

American conglomerate General Electric believes machine-to-machine, or "M2M" for short, advances will fundamentally alter the way business operates.

This morning at its "Minds and Machines" conference in San Francisco GE took the wraps off a new suite of "Industrial Internet" (PDF) technologies and services that it says will help airline, railroad, healthcare, manufacturing and energy companies increase productivity and reduce costs -- $150 billion in waste, it claims.

All this, just by connecting industrial machinery to the Internet (and the people that use it).

The quick and dirty of the announcement:

Who: GE, pitching … Read more

It's been a little heady around here lately: Right after the Lamborghini Gallardo, we get a Bentley -- and a Mulsanne to boot. I normally start our tours of high tech cars in the front seat, but this time we begin in the back where the tech takes off in ways you've never seen before.

If you want iPads in the back seat of your car without buying a Bentley, check out Wayne's how to that can make … Read more

GM extends EV drivability with apps

With current technology, GM can't give its upcoming Spark EV more range, but its OnStar division is giving drivers the tools to deal with limited driving range. A new feature of OnStar's RemoteLink Mobile app will let drivers plan trips based on charging-station availability along a route.

Volt owners use the RemoteLink Mobile app to program charging times remotely. OnStar will add the new Waypoint tab in anticipation of next year's launch of the Spark EV. When a driver enters a destination, the Waypoint feature will plot a route incorporating necessary charging-station stops.

Given that the Spark … Read more

Kettle corn on the kitchen countertop

You know the aroma. It beckons as if it were a magical cartoon hand, wafting through the air until it finds its destination: you. There is no choice but to follow the waggling smoke fingers until you find its source: popcorn. But there is something different about this enticing scent. Tinged around the edges is the distinct sense of sugar and salt. And furthermore, this is not an outdoor event; this is your own kitchen.

Bringing kettle corn to the inside, the Nostalgia Electrics KCP100 Carnival Kettle Corn Maker ($49.99) mirrors the magic of the popular treat without the … Read more

A3 E-tron previews Audi electric car

Ever since 2009, Audi has been showing off enticing electric cars under the E-tron name, its brand for any electrified power train. I finally got to drive one during a green industry conference in San Francisco, but it was a far cry from the original sporty-looking E-tron concept. However, the A3 E-tron looks a lot more like a car that Audi would put into production.… Read more

Tesla Model S: 1st Car of the Year with no internal combustion engine

The 2013 Motor Trend Car of the Year has all the features you'd expect from a vehicle that has earned that honor. It has a light body, advanced design, a roomy cabin, and plenty of load capacity. What the Tesla Model S doesn't have is an internal combustion engine.

Motor Trend heaps praise on the Model S, saying it drives like a sports car and sashays like a supermodel working a Paris catwalk. I never thought about a car being able to sashay, but it's certainly an evocative comparison.

This all-electric supermodel starts at $58,570 and has a range of 265 miles. That's not enough for a cross-country road trip, though a new network of Supercharger fast charging stations could make it more practical for long journeys.… Read more

Tesla celebrates production of 1,000th Model S car

After a sluggish start in its Model S car production, it seems electric-car company Tesla is getting back on track for the year's end. Reaching a milestone today, Tesla CEO Elon Musk tweeted that his company had just finished the production of its 1,000th Model S car.

As noted in Musk's tweet, Tesla has made more cars in October than the whole rest of the year combined. In a July letter to shareholders, Tesla said its Model S volume projection was 5,000 units for 2012. However, Tesla's ability to crank out the Model S has … Read more
