Useful gadget?
Looks pretty good to me. But of course the bureaucracy is dragging its collective feet. They'd rather confiscate tons of deodorants (so we can all feel more Frenchy?) than take the psysicky approach....

Unlike the older units, Diaz said, the HAZAID measures both the speed of sound waves traveling through liquid and the attenuation -- how the waves are altered as they travel.
Good idea to use sonics to test for this stuff. Geologists have been detonating explosives and measuring the sonic return to test for all sorts of fun liquids in the ground. In archaeology, we use (if the funding is there) ground-penetrating radar and magnatometry. Cool stuff that we're able to do with sound.
AI, I had another brainstorm about using sonics. See what you think:
On a drive back from the beautiful Paul Bunyan northwoods of Minnesota to the depressing Red River Valley of Dakota, I thought that we might rig up some sonic device that might also cancel out the verbal diarrhea that you're unfortunately experiencing with pretty regular frequency. I've heard of how it works, a device that emits whatever negative sound in immediate response to the present noise.
I don't know where we'd find such a device though? Maybe you could ask JJ to stop by and ask MIT's tech-guys during one of his Chomsky visits?
