Just a thought...

Since current goes through the shell, it might make sense to use something like: <http://www.grainger.com/Grainger/items/1UYE2> or <http://www.mgchemicals.com/products/8463.html>

I'm sure there's enough surface area for proper conduction without it but you can never have too good a connection and hey, GG owners are perfectionists, aren't they?

Hi my friend Cona,

about the current flow, there is a very large surface for this. Its all the inside body of GG, so imagine a wire that is 4mm fat. These wires are made to delivery very large amounts of current (not only 1,5 ampere like GG)


ps.......As for the link, it does not work to see what you mean

Sorry about the Grainger link. The site is a little odd. To go to the page I was trying to point to, just go to their home page: Grainger Industrial Supply and type into the search window: 1UYE2

Imeothanasis; your wonderful products certainly have enough metal to conduct the current. The reason I'm suggesting that a conductive grease may make a noticeable improvement is because of the thin skin of aluminum oxide which forms when aluminum is exposed to air. While aluminum is a pretty good conductor, aluminum oxide is not. There may be enough resistance building up at this solderless junction to be noticeable to the perfectionists who gravitate to GGs.

Since a few people were craving GGs made from silver, I think it interesting to note that silver is a sensational conductor and unlike aluminum oxide, silver oxide is pretty darn good too.

Thanks again Kona.
Maybe I didnt mention it right but the current goes through the GG but not from the outside surfase only. It goes through all the mass of GG. So even if all GG get "anodised" externally, the current will flow again without any problem.
I hope that this answer will help, because I cant express exactly what I want in english

So that is the biggest advantage of the GG design. Low resistance in the body of the PV = more power to the atty where it is needed.

exactly vapn!
