Francisco Scaramanga cannot contain his glee (or his ego) when James Bond arrives at his island lair.
Taking Double-0 Seven on a tour of the facilities, including his solar energy plant, the notorious hitman demonstrates how he can harness the destructive power of the sun by using a solar cannon to destroy the seaplane that brought Bond to the island.
