These pentagonal pads are powered by small generators, and produce a local zero-gravity field. They emit a blue glow while in use.
Tau Volantis ExpeditionEdit
They were deployed by the SCAF expedition to Tau Volantis in numerous supply silos and archeological dig sites, presumably to allow researchers to study objects in hard-to-reach places. These hard-to-reach places existed because Tau Volantis was once an ocean world, with the result that, being submerged in water, the inhabitants could swim upward to reach those places and did not have stairs or ladders to access those locations.
Events of Dead Space 3Edit
Isaac Clarke traverses the silos built by the SCAF, and reigons under research by the SCAF, encountering these generators in the process.
