This 2.8-mil stainless steel emitter wire is the best we've found to reduce lossy corona and provide maximum thrust and lift for a good antigravity craft. Very strong for its diameter. We don't recommend using other types of wire, such as thin copper filament, as they just don't have the electrical or weight characteristics to work optimally.

This 25 foot spool is good for large craft or experimental AntiGravity Lifter designs, but if you just want to build a standard craft then our 10-foot spool (WIRE2MIL10) should suffice.
