Fuel cells take off

As automakers continue to make progress in the field of hydrogen fuel cells here on Earth, a California company is doing the same thing aloft. AeroVironment, a manufacturer of unmanned planes, announced last week that it had flown its Puma aircraft for nearly five hours using an onboard fuel cell battery hybrid energy storage system.

The Puma, which has a wingspan of 8.5 feet and weighs 12.5 pounds, was powered by its standard rechargeable-battery-powered propulsion system (capable of keeping the craft airborne for 2.5 hours), assisted by an onboard fuel-cell-powered battery. The unmanned aircraft incorporates its own … Read more

Wall-climbing robot sucks it up

Just how desperate is that housewife next door? If those down-looking satellites just don't do it for you any more, here's another way to keep an eye on your neighbor.

The Vortex Regenerative Air Movement Mobile Robot Platform (VRAMMRP) uses a patented "tornado in a cup" sucking technology to stick to walls and ceilings, then uses six wheels to position itself on the window ledge or other strategic location. Remote controlled by joy stick, the unit can send video and audio via secure Bluetooth. This equipment should be included in any self-respecting paparazzi's toolkit.

Permission to board the simulator

Battle stations! The U.S. Navy has upped the stakes in the battle of the training simulators with the commissioning of its 550-foot USS Trayer Battle Stations 21.

The Trayer, dry-docked at a mock pier in the $82.5 million USS Iowa training complex in Great Lakes, Ill., simulates an Arleigh-Burke-class destroyer and some of the adventure and hard work that goes with sailing the Seven Seas.

BTS 21 is part of a 10-year, $763 million "recapitalization" of training facilities that will set new standards in simulation technology by using video screens, smells, vibrations and sound effects to … Read more

Photos: Robots to the rescue

Robots with names like Eyeball, Dragon Runner, ToughBot, Marv, Matilda and Talon fearlessly rolled and hovered over wreckage and rubble last week in Disaster City, a 52-acre training center for first responders and emergency workers.

Last week's robotics exercise, the fourth in two years sponsored by the Science and Technology Directorate at the Department of Homeland Security and the National Institute of Standards and Technology (NIST) at the Commerce Department, has a complex task: finding ways of evaluating performance of robots so that they can be fairly compared, according to The New York Times.

Photos: The Airborne Laser goes to Washington

The bulbous nose on this modified 747 is an early sign of progress in a weapons system that one day may fulfill the goals of the Pentagon's Airborne Laser program. The aircraft recently made its first cross-country flight, landing at Andrews Air Force Base in Maryland--just as Congress is debating funding for the program as part of the overall defense budget for fiscal 2008.

Images: In Paris, the aircraft of the future

There's no time like the present for those who have designs on the future. That's certainly the case at the International Paris Air Show, where aircraft makers have gathered to make deals and show off what they've got on the drawing board.

One company with a particularly lofty goal is Aerion, which wants to get the first supersonic business jet off the ground. The aeronautical engineering venture, based in Reno, Nev., says its plane will be able to fly from Paris to New York in just a little more than four hours--or about three hours ahead of … Read more

Not a bird or a plane, it's Cyberbug

If, on your next flight, you look out the window and see something that resembles a 15-inch, folded cellophane glider zipping by, don't call the USAF crank line. Chances are it's a newly certified Cyberbug.

While unmanned aerial vehicles (UAVs) of all sizes swarm over Iraq, Afghanistan, Gaza and other war-torn venues, they are much more restricted in the skies above the United States, especially those that are experimental. For instance, the Cyberbug is the recipient of one of only 12 "Experimental Airworthiness Certificates" (EACs) issued by Federal Aviation Administration, which allows it to be flown … Read more

Wiping the 21st Century Way

What ho? Why, it's Sir James Dyson, inventor of the luxury vacuum cleaner, loitering about in the men's room. We haven't seen someone with a title in there since Sir Guy Burgess.

He's there to advertise the Dyson Airblade, an energy-efficient hand dryer that strips water droplets off your mitts in six to twelve seconds.

Put your hands in, and a curtain of air traveling at 400 miles per hour removes the moisture. The drying area is relatively small--you can't stick your head in, for instance--but it will whisk away water on your hands in … Read more

Political battles over the Airborne Laser

Remember the scene in Independence Day where the alien invaders blow up the White House with some sort of interstellar death ray? We Earthlings are still a long, long way from that sort of weaponry--just how far will depend, as so many things do, on budget battles in Washington.

The Pentagon's premier "directed energy" weapons system is a missile-zapping laser that could someday soon be tooling around in a modified 747, if all goes right for a program valued at $3.8 billion. This week, the Airborne Laser aircraft paid a visit to Andrews Air Force Base … Read more

In 2004, then-Secretary of Defense Donald Rumsfeld famously told a National Guardsman serving in Iraq, "As you know, you have to go to war with the Army you have, not the Army you want." The soldier had been inquiring about the readiness of Humvees for combat conditions--specifically, the need to "up-armor" the vehicles to provide better protection against enemy fire.

But even if a nation's military has to do the best it can with the gear it has, it can also plan ahead for the gear it knows it will need. That's the dual … Read more
