AUTOMATIC KETTLE
Invented: 1955
Inventor: Peter Hobbs
Inventor: Peter Hobbs
The automatic kettle – one that switches itself off when the water reaches boiling point – was the brainchild of Peter Hobbs, one of the two founders of appliance company Russell Hobbs. At its heart was a simple piece of technology: the bimetallic strip which bent as the water boiled, breaking a circuit and switching off the kettle.
It was British engineer Richard Whitehead who first designed a torpedo launched from a ship in an underwater tube, powered by compressed air and with an internal mechanism that adjusted itself to stay at a constant depth. The first ship to be sunk by his invention was the Turkish steamer Intibah in 1878, after being hit by a torpedo launched from a Russian warship.
