Great find, UT. I can imagine a guy sitting there listening to a stethoscope, when a flock of seagulls comes by.

There's some real ingenuity at work, there. These buggers were not only able to detect the approach of motorized aircraft as far as 15-20 miles away, but also the direction, when a trained ear was involved. Nifty. I'm glad they're preserving a few.

This was, of course, just the allies response to Hitler's dreaded "Das CheericerälÜberWeapon."

A few thousand years later, the inhabitants of Britian wonder what the hell these giant stone dishes were made for, or who made them. One person decides that they were meant to collect rain during a drought, another decides that they were built for a spiritual purpose by a culture of moon-worshippers. (Actually, I think that a reasonably bright person and educated person would be able to figure out what they were supposed to do fairly quickly, although they might be stumped for 'why').

a few thousand years later, the kids will be using their 0 gravity skateboards to shred that bowl, and won't even wonder about who made them.

I've ben lurking and gawking at the images for a few months and finally decided to throw my two cents in (and that's what many of my thoughts are worth)

15 to 20 miles is pretty darned good for something with no moving parts. It would have worked pretty well against the WW1 Gotha bombers moving at around 100 mph under 10,000 feet, but would never give enough warning against modern WW2 bombers or even the slower Stukas. And this 200-foot concrete wall - obviously you can't re-point or aim the thing to check different approaches, although the mechanism to swing it around would have been impressive!

We used to have something like this at the Childrens museum in Indy. The discs were probably on 7 feet tall, and about 50-70 apart. *But* if you were standing in front of the "mic" (which was also the focus point for the parabola you could litterally hear a whisper made from the same spot accross the room. A room filled with screaming children no less.

These sound mirrors are featured in a film art work by Barry Hale called: "Blackout The Antiphony Video Supplement." They were also featured on the cover of Disinformation's "Antiphonny" music cds (1997). The film can currently be seen as part of "The Origin of Painting" exhibition by disinformation, which is currently at Q Gallery, Derby, U.K.

Hey, welcome to the Cellar, youblues. Did you know all that or have to look it up?

I was thinking that if you lined them with aluminum foil you could make a nice solar oven, except for the fact that they are probably facing west and are located in England.

Facing east, over the channel.

I think this may be one of the same thing. He appears to be on a beach and the same time frame.

Wow, a portable model. How convenient! It kind of looks like the arms telescope out? It could also be some 1920's robotic Jai Alai game...

And what a cool religion that would be...
