Tornado Alley (PROG)

[migo]

a fascinating rediscovery!
if true, then this illustrates what may be the tip of an iceberg of lost knowledge.
I can't even begin to imagine the kind of available technology at that distant past to create such a machine as described here, never mind the translation of the observational knowledge into an actually functioning machine.
if true, this tells me how little we really know of our past history as human beings. when this was found a hundred years ago, no one had an inkling of what this device could be.
thanks for posting this story.
