Beams Cook Hot Dogs

Remember those silly, Snopes-debunked stories about cooking an egg between two cell phones? Well, th'ain't nothin' new under the sun. Here's a micro news tidbit from the 1932 Ypsilanti Daily Press announcing that Westinghouse had found a way to cook tube steak with "radio beams":

"Pittsburgh, Ps, Sept. 27 UP--Enough heat to cook a hot dog can be created in a field of radio beams, radio engineers of the Westinghouse Electric and Manufacturing Company claim. Despite the heat caused by the beams, the two discs between which they pass remain cool to the touch, it is said."

Hm. Was this a precursor to the microwave oven? Thought that didn't come along till WWII. Hm.
