Following are some links to information about "wire brush" static dissipators.

        It seems that cosmic rays produce the ionization  trails that the 
static charge follows to produce lightning. You can't stop cosmic rays nor 
can you discharge a cloud or earth to prevent lightning. However, such 
devices can be used as lightning rods. They are about as effective as a 
single lightning rod in determining where the lighting is going to strike 
your tower or house. So if you use such a device you must have a hefty 
ground wire and ground to carry the current safely to the earth.
    Also, if lightning does strike the porcupine or wire brush there may 
be a hundred  red hot needles (darts) shot in all directions when it hits. 
Could make things a bit exciting.
