Object statement
Incandescent lamp, socket and short antennae, for demonstrating lighting of lamp by wireless. Used at Westinghouse exhibition at Chicago Century of Progress Exposition, in the demonstration "Power by Radio" (SB).
A letter from Colin Lee to curator Arthur Penfold states that 'the incandescent lamp, socket, and short antennae, which I have given to Mr D T Hinchen to deliver to the Technological Museum, is one of those used at the Westinghouse Exhibit at the Chicago Century of Progress Exposition, in the demonstration of "Power of Radio".'

This demonstration involved radiating 7.5 kW of energy at 50 million cycles per second. This activated a standard one-eighth horsepower DC motor sitting 20 feet away, and turned on hand-held lamps fitted with antennas over 200 feet away.

Later notes on the object file refer to the apparatus as being 'like those used' at the Expo.
