H₂O scoop



An H2O Scoop was a method of transportation over long distances, probably about one million miles in twenty seconds, used by the Judoon to transport locations from planets they had no jurisdiction (such as the Earth), over to neutral areas, such as uninhabited moons. (DW: Smith and Jones)

Process
The H2O Scoop process would start with plasma coils being placed around the location which was to be transported (which would cause an unusual static build-up in the area). A few days later a raincloud would form over the location, but nowhere else (as Tish Jones pointed out that it's like a cartoon where there is a rain cloud over somebody's head). A short thunderstorm would follow, which ended when the rain from the storm rose back into the cloud. After a short period and a flash of light, the location would be transported.

If the destination did not have a life-sustaining atmosphere, a force field would be placed around the location to keep the inhabitants alive. (DW: Smith and Jones)

The Judoon used an H2O Scoop to teleport Balmoral Castle into a desert. (NSA: Revenge of the Judoon).

The Night Travellers were said to "come out from the rain", perhaps implying that some sort of H2O Scoop technology was used to transport them. (TW: From Out of the Rain)

The way the Uvodni teleported people was similar to the H2O Scoop. (SJA: Warriors of Kudlak)


 * It is possible that the Scoop is not just used by the Judoon.
