| 1. An electrostatic, airborne particulate precipitator comprising:
a housing unit;
a first conductive electrode located in said housing unit;
a second conductive electrode located in said housing unit at a distance from said first conductive electrode, said first
and second conductive electrodes comprising poles of an electrostatic field; and
a carbon nanotube formed on said second conductive electrode, wherein said carbon nanotube comprises a shape sufficient to
ionize gas in said housing unit.
