ROBOT PLAYS PHONOGRAPH
Sir Robot, looking like one of Coeur de Lion’s knights, is merely placing a record on the portable before him.

• LARGEST RADIO TUBE •
The 500-kilowatt transmitting tube, shown in the picture at the right, was on exhibition at the London exposition commemorating the 100th anniversary of the discovery of magnetic induction by Michael Faraday—for whom the farad is named. All electrical and radio development since then has been based on his work. General J. C. Smuts, president of the British Association and noted scientist, who opened the exposition, is at the left.

• WORLD’S LARGEST SPEAKERS •
The two instruments shown below are models at the Olympia (London) exposition.

The house-like edifice shown in the center of this bottom row of pictures, is believed the world’s largest ; it may be compared with its parent, the actual commercial model, which the young lady is holding. The speaker unit at the right is the biggest cone yet produced. Speech from this may be heard over a distance of three miles. # (Keystone Views)

    I wonder if the Robot was an early version of the tin woods man or See Threepio.

    Maybe its not a robot at all, but rather an early full-body suit for welder protection…and he just wanted to listen to some Mozart while he worked…?

    If I am right, those giant tubes were used in early radio stations’ transmitters. They produced such huge amounts of waste heat that they had to be water-cooled, and this gave rise to the derisive term “steam radio”.

    Stephen: Not at all. There are too many instances of people referring to their home receivers as “steam radio”. Steam as an adjective just means old fashioned or pre-digital age as in “steampunk” doesn’t mean water cooled science fiction but anachronistic technology in a 19th century setting like The Wild Wild West TV series.

    In the first link I provide the earliest reference to the term is found in 1951.

    Now we see where urban legends come from.
