The Solex Agitator is a small but very powerful device, used in the movie The Man With The Golden Gun (1974). In the film, the Solex Agitator is a device which can harness solar energy, created by British scientist Gibson as a solution to the global energy crisis. Gibson gets killed by Francisco Scaramanga (Christopher Lee) and Nick Nack steals the Solex after the assassination. Scaramanga then offers the Solex to the highest bidder, and includes a solar-powered laser cannon with it, "no extra charge". Eventually James Bond (Roger Moore) and Mary Goodnight (Britt Ekland) are able to get the device back.
The Solex Agitator is a fictional device, and it was designed and created for the movie. One of the original movie props was sold at an auction at Christie's in 2012 for £55,000 (approx. $85,000 or €70,000). The item on auction has a circuit board encased in resin, the metal casing engraved on the front H/220, and engraved post-production 'James Bond', the back engraved A/6B and H/220, with a Bond archive label.
In 2014, a very accurate prop replica was created by Bond fan Quartermaster Mick (see photo on top of this page). The case of the replica is machined from a solid aluminium block. The electronic circuit board and components are encased in clear resin, just like the original prop. There are over 50 component parts used in the piece.
