History of Television in Rikutso

Televisions in Rikutsar are much older and far different from Televisions in the rest of the world. The ancestor of the modern version was invented in 1678 by Royal Scientists experimenting with the light sensitivity of selenium cell phototubes, which were also invented long before its contemporary versions (in the Rikutsaren Electricity Rush) and are different in certain aspects from them.
 * The selenium used for the tubes is relatively common in Rikutsar, as the volcano which formed the island was originally a rich hydrothermal vent field that deposited Aguilarite (Ag4SeS) and Naumannite (Ag2Se), along with Acanthite (Ag2S), and Pyrargyrite (Ag3SbS3).
 * Rikutsar makes high use of Silver due to its abundance, as well as due to the very low numbers of deposits containing cheaper metals such as Aluminium or Iron.

Televisions in Rikutsar are normally circular or oval in shape, usually within a triangular or trapezoidal case of silver-copper alloy. Signals are sent to the television set from a camera via dense matrix of 15,000 - 20,000 selenium phototubes within the camera. The receiver is another matrix of similar size which projects the image onto a rapidly rotating metal disk within the television that has 500 - 1000 very small holes in it, similar to a very advanced Nipkow disc. The image from this disc is projected onto a translucent glass panel. Rikutso has successfully managed to downsize selenium phototubes efficiently.

Television signal in Rikutsar was for a very long time transmitted over wire (in some areas as recently as 1960), but was quickly replaced with wireless once news of wireless research came in from Rikutso's infamous "scientist spies" who were implanted in almost every university and government science lab in the world.
