Passive conveyance is the direct forebearer to direct conveyance. Using a form of reverse-diffusion, the tralaticon-alloyed devices draw elements from the environment similarly to reverse-osmosis water systems. This process is slow and requires many units operating together in close proximity to a Root of the World or Primal Current. Passive conveyance has been completely eclipsed by direct conveyance as a method for large scale power production.
This technology has not completely disappeared, however. Recent innovations which lighten and miniaturize the devices have produced Extractors. Even so, they are still cumbersome: weighing around 25 lbs and requiring a backpack harness with various wires, dials, and gauges wrapping around the user on a metal arm. Drawing on element energy stored in tralaticon batteries, a skilled user is able to weave the elements together and produce effects that would otherwise require impossible or very specific natural conditions. Flooding can be produced in a desert, wind can now blow in deep caves, and solid earth is raised up without equipment. As powerful as this invention is, the batteries drain quickly and take long hours to recharge. The skill of the user can increase the amount of usages, but it is still a limited technology.
