Working on the Plan Part 2

The success of the twenty-meter test did not make Ernest relax.

If anything, it made him more cautious.

A small telegraph circuit inside Laboratory Number One proved that the principle worked. It did not prove that the device could survive real use. It did not prove that the battery could remain stable for days. It did not prove that a signal could travel across hundreds of meters, much less from the Royal Palace to Northport. Most importantly, it did not prove that ordinary workers could operate and maintain the machine without Ernest standing beside them.

That was the difference between an experiment and an invention.

An experiment worked once.

An invention worked repeatedly.

A military communication system had to work when rain fell, when operators were tired, when the wire sagged, when batteries weakened, when officers shouted, and when nobody had time to calmly think through problems.
