Al >irritating a few independent hams.

The 1970s-80s could be called the "golden age" of ham radio. There were virtually 1000s of hams on the SW bands at any one time. In fact, 1980 was the top of a sunspot cycle and so it was possible to make very long distance coms using tiny transmitters. You can just imagine the havoc the Woodpecker caused with its 50 megawatts.

That hypersonic sound is interesting but I think it will need a lot of development before it is feasible for general applications. A particular problem is that it will drive domestic pets crazy because they hear the high frequencies so the beam concept would not work. As you say, it could probably be used for torturing prisoners or, as the article says, customers.

I particularly liked the award to....
>>>those connected with Enron - who shared the Ig Nobel Prize for Economics. They win the award for "adapting the mathematical concept of imaginary numbers for use in the business world.<<<

I imagine Dubya would win the Ig Nobel prize for peace. Wouldn't be much point in giving it to Cheney because no-one knows where he is.
