This hut is claimed to be the site of the first radio broadcast, by Marconi employees (see marconi figures).
It is now part of Chelmsford's industrial museum at Sandford Mill. The commission was to
make a set of exhibits to explain the basics of electricity. These are a few of them
ELECTRICITY, HEAT AND MAGNETISM
The idea was to show that electricity flowing through a circuit makes the wire magnetic
and hot. We used a car battery so the effect would be easily noticable. Although we
included various safety devices, the red hot wire was thought to be too dangerous so this
exhibit is now run as a demonstration.
