Pulse Detonation Engines: The Future of Aviation
noah_fense writes "Popular Science is running an interesting article about the race to replace the jet turbine with a more efficient source of Mach-breaking airpower: the pulse-detonation engine. It works by detonating (instead of slow burning) fuel hundreds to thousands of times a second. PDE technology is poised to make supersonic passenger flights and space travel affordable. 'Pulse detonation is a hot topic in combustion research,' says Gabriel Roy of the Office of Naval Research. 'Compared with gas turbines, the PDE has a much simpler configuration. It has the capability of going from subsonic to supersonic using less fuel, and it's thermodynamically more efficient. But there are big engineering issues--thermal fatigue, noise. It's very challenging research.'"

Sounds like they're strained for humor over there.
The coolest voice ever.
most of them probably won't make it across the english channel.
"...But there are big engineering issues--thermal fatigue, noise..." ...Potential explosions...
...we might finally get affordable supersonic jet transportation?
I can't stand flights of over an hour or two myself, and it would probably encourage even greater mobility then we have today if it's cheap enough. For example, transcontinental dating.
Is this what they are talking about? Dr. Fun
well if you can get power from an Anonymous Coward, slashdot should have the energy market cornered...
I suspect that "blowing shit up" is another one of those big issues.
I've found that my posts don't format quite right w/o a sig.
Why have you been keeping the reindeer propulsion system a secret from the world? You should really consider putting it under the GPL for the world to benefit. Yeah, I know, you got laughed at when you tried to sell it, and so you see no potential profit from it, but that's exactly the reason why you need to GPL it! If you GPL your tech, then once people stop laughing, they'll see that's it actually works. The world could really use something like that.
If you can get presents to all the world's children in one night, you certainly have something that can move faster than anything we have now.
Speaking of children, I'm going to be taking care of a child this Christmas and he really, really wants a new NVidia card. Maybe you could come here early and drop it off so I can make sure it works on our computer! I'll be sure to not let him see it before Christmas, promise!

I notice in the pictures that the lady standing next to the engine on the second page has no head.
An engine that decapitates people is certainly very injurous to health.

You're right, I wouldn't steal a car. But if it were possible, I sure as hell would download one!
Have you seen the very weird picture of a woman with no head and a deformed right arm on page 2 of the article? I wonder if she stood too close when the engine was switched on.

...any moment now!"
Three things:
Heat expansion of metals.
Pipe-organs.
Fluidics.
I'll leave the rest to you
PROFIT?
