The Thought Projector is a machine that allows the user to communicate through thought to a particular individual, across great distances, even if the user doesn't know exactly where that individual is located. Flash Gordon uses Thun's Thought-Projector, which is located on Thun's smashed Space Gyro; the machine is apparently standard equipment. Through the Thought-Projector, Dale tells Flash that it's hopeless to try to get back to her. When her pleading is cut short, Flash realizes that her mind is no longer working. ("On the Planet Mongo")
