A good indication of the voodoo "science" involved in that link is the fact that he built it with 500 (!) points. Ask yourself what 500 sharp points would do that a few pointed different directions wouldn't. In fact, pack enough points grouped close together and you make the static field effect approximate a smooth sphere.

I'm always amazed that a hobby like ours, supposedly based in physics and the real world, perpetuates so much garbage like this ... especially when there are much more rigorous studies readily accessible out there on the internet to debunk it.

This topic has been discussed too may times and there seems to be nobody with a

make. I haven't gotten any lightning strikes in them during the few years the 
tower been up. That doesn't mean they are effective. I have notice that I have 
had no strikes on my house, something that happened on a relatively regular 
basis, since the tower went up. I think the tower itself was the contributing 
factor to that, though.

I had a 0-0, stranded aluminum cable at hand when I raised the tower and 
decided to put three, one on each leg, of them up. You can  view they on my 
facebook page. Does it work? Honestly, I have no idea. I do think that you can 
build these dissipators yourself for a much lower price than what they are 
offered at.

Ran across this looking for something else and noticed a section on towers, 
grounding and other items we are all interested in. Sample article.
