From: " Henrik Larsen" Teleportation (TL 15+) Prolog: This is thought as an expansion on the teleportation-material in Gurps Ultra Tech, defining the subject more clearly. The prices included are, of course, only suggestions. Any setting at such a high TL is impossible to predict economically (the Star Trek universe is said to have no monetary system at all). Thus, the GM should only consider the prices guidelines to comparing these items to each other. Teleportation Mechanics: Teleportation is achieved by sending an item through another "dimension". This dimension is not as much another place as it is a sub-structure of the universe. Each item is designated a set of coordinates in this "dimension". These will here be called quantum coordinates (this is in no way a hint at quantum mechanics making teleportation possible; it is just a fancy name). These make it possible to displace the item teleported. How they are used is indicated in the descriptions of each method of teleportation, below. Transfer Teleporters (Matter Transmitters)(TL 15) These teleporters are the most basic, and the first to be developed. They transport the teleported item or person from one booth to another. Each booth has to be connected to the other enough for information on the quantum coordinates being used for the transfer. Booths can be inter-connected like a modern day phone-grid, allowing someone to send to or from any booth connected to the grid. It is not possible to teleport to or from several booths at once, though (no object duplication). The cost of a booth is $500 per cubic foot transfered. It weighs 50 lbs. per cf. transfered. A Complexity 15 computer is also needed to communicate the transfer with the recieving end. The price to be part of a grid depends fully on the grid providers, and the setting. Usually, transfers can be made at any distance, only limited by the possibility of the computers to communicate (if STL communication is used across longer distances, increase transfer time by twice the time required for messages to cross the gap (first time for sender to notify reciever, second time for reciever to reply with an acceptance). Time required for a transfer is 20 seconds per lbs. (not cf.) divided by (TL-13) (10 seconds per lbs. at TL 15). Power requirement is 50 mW (mega-watt, or 1000 X kW) per lbs. transfered, not counting the power required by the computer (which must be on during the entire transfer). While installing a matter transmitter requires Electronics (Teleporters), using one requires no skill; just push in the target booth number and go! (GMs may should Electronics Op. (Teleporters) to change the booth number, though). Displacement Teleporters (Displacers) (TL 16) These teleporters use only one booth. They can either send an object from this booth to anywhere within reach, or snatch something back to the booth. This is achieved by opening the quantum coordinates andfully pushing or pulling the object through before closing (transfer teleporters expect the other side to pick up the object). A Displacers reach decides whether an object can be send to or grabbed from a place. The basic reach is one yard, but this can be increased by increasing cost and weight of the booth by 10% per additional yard (making far-reaching teleporters like those for orbit-to- surface displacements very costly (and large). The booth itself costs $750 and weighs 100 lbs. per cubic foot transfered. A Complexity 18 computer is required to handle the coordinates and displacement, but communication is not necesary. Any displacer-computer comes equiped with safety features, which avoid displaced items or person being locked inside mountains or deep beneath oceans. If such situations are required, an Electronics Op. (Teleporters) must be made. Time required is 3 times that for matter transmitters, and power requirements are 5 times as much! Using a displacer requires a roll vs. Electronics Op. (Teleporters) to capture and aim the quantum coordinates. A system can have sets of coordinates permanently installed (another roll), but these coordinates will displace an object relatively to the *displacer*! Thus, if a starship sets its coordinates for displacement at 200 miles below the ship, anyone using those coordinates after the ship has left the planets orbit will still end up *200 miles below the ship*, not on the planets surface as before departure. Self-sending Teleporters (Endoporters) (TL 17) The ultimate in teleportation, these teleport *themselves* along, allowing the user to teleport to and from any location, without the need for booths (although the endoporter could be designed to look like one). They project the quantum coordinates around itself, thereby negating the need to move the object (and itself) through. Endoporters cost $1500 and weighs 120 lbs. per cubic foot teleported (not counting itself, though). A Complexity 20 computer is required to make the transfer. Time is 5 times that of matter transmitters, and power requirement is 20 times (!) as much. Rolls for quantum coordinates are as for displacers. All teleporters shrink with advancing TLs; halve weight (and thus size) for each additional TL (although booths will always have to be able to hold the objects to be sent). Power is halved each TL as well, but only for the first 3 TLs after invention of the teleporter type; after that, it is fixed. Range of displacers does not increase, but the size of the displacer gets smaller, as noted, while the range stays the same. Teleporter-related Equipment: Telescanners (TL 17) These devices detect any objects being teleported into or out of any point within their range. They are meant for detecting displacings and endoportations, but can also detect activated booths. They basically give a low blip upon detection, in addition to an indication on a simple view-screen. They cost $500 X range in tens of yards and weigh 3 lbs., plus 1 lb. per ten yards of range. For an extra $200, a mapper is installed, adding a holographic map of the surroundings to the view-screen. Another option is a "teletracker", a TL 18 device, which can detect the coordinates from where the teleported object came or is going. It weighs 2 lbs. extra. The user can just tap on the signal of a detection to call up teleportation info. Interrupters (TL 19) These are (often highly illegal) devices, which access a teleportations quantum coordinates and redirects the sent object to a pre-designated booth. Interrupters require a fully equiped displacer system, and some special hardware costing $5000 (price often driven way higher by black market influences). A special program, supplied (usually) with the special hardware must also be installed in the computer. When an interruption is made, roll a Contest of Electronics Op. (Teleporter) Skills (Expert programs in the computers can be used). On a win by the interrupter, the transfer is diverted. On a loss or tie, the transfer goes as meant. Beacons (TL 16) These devices weigh only 1 lb. and cost $200. They use a dedicated Complexity 4 computer (at this TL, they are miniscule) to find its own coordinates, and sends them to a displacer or endoporter, which can then transfer the object to them (displacers can also transfer from the coordinates, taking the beacon along or not (usually a pre-set choice, with changing it simply a matter of telling the computer; no skill roll). The benefit of beacons is, that no Electronics Op. (Teleporter) roll is required to connect to a location; simply get the beacon there and push the button. Of course, getting the beacon there can be a tough job in itself. Reality Stabilizers (TL 16) These work as in Ultra Tech. They totally counter any attempt by lower TL gadgets to teleport into or out of covered areas. Same or higher TL devices roll a Contest of TL to see who gets the "right of way".
