Vehicle-to-vehicle communication

[podcast]http://edwardwillett.com/wp-content/uploads//2012/01/Communicating-Cars.mp3[/podcast] Do you talk to your car? I know I do (perhaps not as much as I, um, “talk” to other drivers, but some). I think I inherited the trait from my mother: all of the cars of my childhood, I knew from her, were named “Suzy.” These days, your car may even listen to you, if you have a voice-activated music system or phone. But generally, cars don’t pay much attention to what you say to them. It could be that you just don’t have anything to say they’re very interested in. Perhaps what cars would really enjoy is conversation with others of their kind...and it may not be too long ...

D-Dalus: Dawn of the flying car?

[podcast]http://edwardwillett.com/wp-content/upLoads//2011/06/Dawn-of-the-Flying-Cars.mp3[/podcast] “Hey, dude, where’s my flying car?” is a cry every science fiction writer has heard—and every science fiction reader has uttered—since the future supposedly arrived on January 1, 2001, and we found ourselves still stuck to the ground, rolling along on rubber tires. The problem has been that we really only have a few ways to get ourselves into the air, and none of them really lend themselves well to flying cars. But a new technology presented at the Paris Air Show proffers the possibility of, not only flying cars, but more stable, easy-to-fly and mechanically robust aircraft for a plethora of purposes: the first “disruptive technology”—technology that changes everything and ...

Red means stop, green means go, yellow means…?

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/06/The-Yellow-Light-Dilemma.mp3[/podcast] I went through a yellow light today. I’d glanced away at the wrong moment, looked up to see the light had gone yellow, and realized I couldn’t stop without slamming on the brakes and probably skidding into the intersection. Later, I was crossing a street downtown when a van went through the yellow in front of me. It looked to me like the driver had plenty of time to stop—but no doubt he had his own excuse. It’s a rare driver who doesn’t run through a yellow light on occasion, and in most cases it’s barely even a conscious decision. You have a split second to decide to brake, keep going...or even speed up. So how do we make that decision? A transportation engineering ...

Fuel from germs

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/Fuel-from-Germs.mp3[/podcast] For years, we’ve been turning crops such as corn, wheat and sugar beets into fuel, using yeast to convert sugar into alcohol. But there’s an obvious problem with this. That stuff we’re turning into fuel is also food for humans and feed for animals. (And as an aside, how come we always call it “animal feed” as opposed to “animal food”? And why don’t we ever refer to “human feed”? Hmm?) A lot of the plant is wasted when you grow crops for fuel or food. The leaves and stems, with their tough cell walls made of cellulose, hemicellulose and lignin, are more of a nuisance than anything else. Wouldn’t it be great if there were a use for what is now plowed ...

Liquid fuel from solar power

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/07/Liquid-Fuels-from-Solar-Power.mp3[/podcast] In recent years, scientists and engineers have turned to biofuels—fuels generated from living things, and hence renewable—as a means of weaning us off of fossil fuels in favor of something cleaner, less likely to run out, and less wrapped up in international geopolitics. Fermenting the sugars found in corn or other grains into ethanol has been around for a long time, of course, and it’s pretty much a proven technology. On the other hand, do we really want to be turning food into fuel? More promising have been recent advances in turning lignocellulose, the stuff that makes up the cell walls in plants, into ethanol and other fuels: that would allow us to use grasses, wood chips, straw and other non-food as ...

The washboard effect

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/07/The-Washboard-Effect.mp3[/podcast] Saskatchewan, as has oft been noted, has a lot of roads: more than 190,000 kilometres in all, in fact, giving it one of the most extensive road systems in Canada. Not all of those roads are paved, however. In fact, most aren’t. And as anyone who has had occasion to drive extensively on the rural road system can tell you, while gravel roads are better than mud roads, they have their own...interesting...characteristics, of which one of the most annoying is the “washboard effect.” Washboards are fine if you’re a 19th century pioneer woman trying to clean the clothes or the abs of a 21st century male bodybuilder, but washboard-like ridges on a road are downright dangerous, reducing traction, causing extreme wear and ...

Airships, airships, airships!

I've blogged before about my fondness for airships. Popular Mechanics has a roundup of some of the latest developments, should you share my odd obsession.(Via Instapundit.)

A 737 hitchhiker?

This is literally unbelievable:MOSCOW, September 24 (RIA Novosti) - A 15-year-old boy from the Urals suffered acute frostbite after riding the wing of a Boeing-737 plane on a two-hour flight from Perm to Moscow, Russian radio station Mayak reported on Monday. After clinging on for the entire 1300-kilometer (808-mile) flight to Vnukovo Airport, the boy, named Andrei, collapsed onto the tarmac. His arms and legs were so severely frozen that rescuers were at first unable to remove his coat and shoes, the radio station said. What on Earth is there to hold on to on a 737's wing? At 900 kph?More likely he was in the wheel well, if this incident really happened at ...

Candle on the water

Download the audio version.Get my column as a podcast.***Lighthouse keeping has always sounded like a romantic occupation to me. As a kid, I even won honorable mention in a creative writing contest with a story featuring a lighthouse keeper.Of course, being a prairie boy, I had never actually even been in a lighthouse. And that held true until just recently, when, on a trip to Ontario, I climbed two of them, on the shores of Lake Huron.Lighthouses are not a new invention. The Lighthouse of Alexandria, one of the Seven Wonders of the World in ancient times, was built in the third century B.C. and stood something between 115 ...
