Rocket scientist aims to relaunch propulsion technology

The time has come to jettison the traditional chemical rocket propulsion system and move to one powered by beamed microwaves, say a group of researchers.

For decades, even as rockets have gotten lighter and more powerful, the basic system for putting them in space hasn't changed. A combustion chamber is loaded with propellants, which are put through a chemical reaction, causing hot gases to accelerate and be ejected through a nozzle at very high velocity, which in turn, provides momentum to the rocket's engine.

But a team led by 25-year-old CalTech Ph.D. student Dmitriy Tseliakhovich thinks that … Read more

Wrapping up a fantastic Road Trip 2010

SAN FRANCISCO--As someone who grew up a political junkie, I was always hard-pressed to explain why I had never visited Washington, D.C.

I don't have to make excuses anymore, not after Road Trip 2010, my journey up and down the American Northeast that began in D.C. on June 23 and ended Saturday in Orlando, Fla.

Indeed, the trip--which covered 5,266 miles of driving in a Porsche Panamera through Washington, D.C., Virginia, Maryland, Pennsylvania, Delaware, New Jersey, New York, Connecticut, Massachusetts, Rhode Island, New Hampshire, Vermont, and Maine, and an accompanying jaunt to Florida--was an opportunity … Read more

Behind the scenes at GE Global Research

NISKAYUNA, N.Y.--When you're listening to someone explain a new scientific method and just about the only thing that goes through your head is "This is going to win a Nobel Prize," you know you're in good company.

That was my experience recently while I was listening to Fiona Ginty, a project leader in computational biology in General Electric Global Research's biosciences group, explain her work. Ginty's project is all about finding new and better ways to spot cancer in a patient's body, ideally as early as possible. And as a member … Read more

Inside the Navy's next-generation destroyer

PORTSMOUTH, R.I.--As someone interested in the cutting edge, one of the best things about Road Trip 2010 has been getting a rare look at the U.S. Navy's next-generation aircraft carrier and the world's most advanced submarine.

But that wasn't enough for me. I also had to see where the Navy is going with destroyers, and that's why my visit to Raytheon's Seapower Capability Center here was such a good investment of time: I got a chance for a lengthy discussion on the next-generation, Zumwalt-class guided-missile destroyer, which the Navy expects to be … Read more

At Raytheon, where engineering rules

WALTHAM, Mass.--For Mark Russell, the vice president of engineering, technology, and mission assurance at defense giant Raytheon, engineering is not just his profession--it's also the lifeblood of the company.

It seems pretty obvious that engineering would be important at a company that makes just about every imaginable kind of defense system. But this important? At Raytheon, more than 40,000 of the total 75,000 employees are engineers, and the company is hiring thousands more each year.

To Russell, who grew up in the company (he's been there 27 years) it's a no-brainer that all six … Read more

At IBM Research, a constant quest for the bleeding edge

YORKTOWN HEIGHTS, N.Y.--When you think about diverse issues like river management during drought, urban traffic prediction, cocoa crop maximization, and how to win at Jeopardy, IBM might not be the first company that comes to mind.

But as unlikely as it might seem, Big Blue has its hands in all four of those areas and many, many more, all part of its IBM Research division, a sprawling organization that seeks to keep the company at the bleeding edge of the world's most pressing technology problems and to help it and its partners develop products aimed at solving … Read more

Harley-Davidson's latest and greatest bikes

YORK, Pa.--Take the world's most iconic motorcycles. And take industrial geekiness at its best. Mix the two. And what you get is what I'm looking at: the production lines of the 2011 model year Harley-Davidson touring, Softtail and "trike" motorcycles.

I've come here as part of Road Trip 2010 knowing that there are few ways more popular among those who travel the highways of America than Harleys. When planning this visit, I had in mind the motorcycle version of the story and photo package I did on the Corvette assembly plant in Bowling Green, … Read more

In Vermont, Ben & Jerry's ice cream is king

WATERBURY, Vt.--You wouldn't think that half a million people a year would trek to this tiny town in the middle of the Green Mountain state, but then again, you might not know that this is mecca for ice cream fans.

This, of course, is where the original--and still operating--Ben & Jerry's production plant is located and where about 250,000 pints of the confection still come off the line every day.

Back in 1978, Ben Cohen and Jerry Greenfield served the first scoops of their soon-to-be famous ice cream from a small shop in a gas station … Read more

The future is now at MIT Media Lab

CAMBRIDGE, Mass.--If I learned one thing Thursday, it's that I want a folding car.

You might laugh at that notion, but I'm here to tell you it's not fantasy: the folding car is coming, and if it succeeds, it could change the way urban environments look forever.

That's my take after a visit to the MIT Media Lab here, the 25-year-old hotbed of research and innovation that has produced the underlying technology behind things like Guitar Hero, Lego Mindstorms, E Ink, One Laptop per Child, and much, much more.

Behind the scenes at the Samuel Adams brewery

BOSTON--If it were any other day, and I was tipsy from drinking beer on the job, particularly given that it's not even noon yet, I'd probably be in serious trouble.

But today, I've got an excuse: I'm at the Samuel Adams brewery here for a behind-the-scenes tour of the famous facility. And they've got me sampling the wares.

I'm here on Road Trip 2010, which has taken me to a wildly diverse collection of places up and down the Northeast, but all I can think right now is that drinking amazingly tasty specialty beer … Read more
