Systems, devices, and methods for collecting species from a gas stream

A species collection device comprising:

• an emitter electrode;
• a mesh electrically conductive collector;
• and
• one or more tensioning cables,
• wherein the one or more tensioning cables run through the mesh collector, and the one or more tensioning cables hold the mesh under tension.

A system for collecting water from a plume emanating from a gas outlet, the system comprising:

• a plurality of electrically conductive collectors that are spaced apart;
• and
• a plurality of emitter electrodes,
• wherein at least one of the plurality of emitter electrodes is disposed between an adjacent two of the plurality of electrically conductive collectors,
• wherein the plurality of collectors and the plurality of emitters are disposed at the gas outlet such that the plurality of emitters are operable to cause the water to be collected from the plume by the plurality of collectors, and
• wherein (i) the at least one of the plurality of emitter electrodes comprises two emitter electrodes, (ii) one of the two emitter electrodes is maintained at a first voltage and the other of the two emitter electrodes is maintained at a second voltage, wherein the first voltage is higher than the second voltage, and (iii) the one of the two emitter electrodes is closer to the gas outlet than the other of the two emitter electrodes.
