Market Grows for Robot Planes

August 12, 2009 5:28 am | by Andrea Shalal-Esa and Phil Berlowitz | News | Comments

A drawdown of U.S. troops in Iraq may slow sales of some unmanned aerial vehicles after years of exponential growth, but demand from civilian agencies and foreign countries will underpin the market for years to come, industry and defense officials said on Tuesday. Northrop Grumman Corp, maker of the high-altitude Global Hawk, and privately held General Atomics, which makes the Predator and Warrior unmanned planes, are among hundreds of companies showing off drones, robots and sensors at the world's largest unmanned systems conference in Washington this week. Northrop and General Atomics dominate the unmanned airplane market, but many other companies are vying for a share of a market that the Virginia-based Teal Group estimates will be worth $62 billion over the next decade.

First Wi-Fi Pacemaker Debuts

August 11, 2009 6:57 am | by Ben Gruber and Belinda Goldsmith | News | Comments

After relying on a pacemaker for 20 years, Carol Kasyjanski has become the first American recipient of a wireless pacemaker that allows her doctor to monitor her health from afar -- over the Internet. When Kasyjanski heads to St. Francis Hospital in Roslyn, New York, for a routine check-up, about 90 percent of the work has already been done because her doctor logged into his computer and learned most of what he needed to know about his patient.


A Bold Claim: Chevy Volt Gets 230 MPG

August 11, 2009 6:53 am | by by Jason Lomberg, Technical Editor | Blogs | Comments

Fool me once, shame on you. Fool me twice….well, you know the rest. When Raser Technologies claimed their re-jiggered Electric Hummer got 100 miles per gallon, I thought they fudged a few numbers. But for GM to claim 230 MPG for the Volt…well, that’s taking a trip to fantasyland, with magical goblins and unicorns.
