My thought is to use it instead of copper foil or tape on tapers such as P60 type drop ins or on pressed fit joint to improve conductivity. I understand completely that that stuff is microns as far as thickness goes but it’s not that expensive and may be worth it on a tight joint.
Gold will conduct less heat than copper.
Electrical conductivity… And I dunno about the heat thing so I won’t argue. Although if someone would like to supply me a chunk of gold to do some tests I’ll gladly pay for the shipping.
And my search has now turned to silver leaf/foil. Let’s see what Google finds for me. Thanks flashpilot.
It’s available. ill still want the gold for the electrical properties on presses fit stuff. Maybe something as little as a couple little balls of it in the bottom of a bore or shelf. It for sure couldn’t hurt anything.
Keep in mind that silver can oxidize fairly easily. I wonder if anyone makes iridium plated silver foil, or at least a treated silver foil that contains some type of antioxidant.
Sterling silver would cure most of the oxidizing problem. I know it comes in gauge size sheets and wire.
I think the glue used to stick it is also gonna have some negative effect.

sooooo… why isn’t there a diamond-flashlight yet? :money_mouth_face:
Already is. Daimond = carbon. Carbon fibers are used to build flashlights 
Because... dissipation off the outer surface of a light is the limiting factor and the material(s) inside make hardly any difference at all?
If you use your light while submerged in liquid nitrogen, then the diamond light might show some measurable increase over a crappy plain aluminum one. But you'd probably have other things to worry about.
