Title: Graphene Wire
Post by: rollo on September 29, 2017, 07:34:31 AM
  According to the scientists graphene will replace copper some day. Better conductor, no skin effect, low inductance, low capacitance, no dielectric required. Makes sense however the only question is, what does it sound like ?

Graphene will probably be used to facilitate the further miniaturization computer processors in its first applications. As far as how it sounds when used as a signal carrying conductor in audio, that point may be moot if all future releases are given the MQA treatment.
 I am still waiting for a graphene based supercapacitor that can replace lithium batteries in everything.
If the sound of wire is due to LCR effects or other things I can't put a name to graphene, may have no sound at all.
 If it is really a game changer we not be able to tell what it is doing, because we will be hearing effects from upstream components. Damn hard to evaluate if this turns out to be the case.

Scotty it appears that the first use will be in chips. Temp is much less and speed is incredible. Yes Sir those supercaps might be some change for us.
Scotty not that sound is due to LCR it is the LCR mix that gives us that sound we like. Future looks good.

From the videos I have seen about making graphene, might be as simple as coating a wire with a thin graphite paste and then hitting it with a laser.  The way they did with using a DVD player, but just a handheld unit. 

Since the two will be in parallel, the one with the lowest resistance and inductance will prevail, where the capacitance will still depend on spacing.

Might be a fun project to try as a start.

  Go get em Tiger. I saw graphene coated copper for sale now. All graphene conductors baby !

Just got an email from VH Audio and they’re offering the Synergistic Research Blue fuses with UEF graphene (not sure what uef is). First time I’ve seen graphene mentioned with fuses. The fuses are quite pricey  @ $149.95, so I’m not a buyer.

   Yup. $150 ea. is hard to swallow however you will be glad you got one. FRANKENTWEAK. Ya cant get a better conductor for power than Graphene.
I want Graphene power cord to try. Right now those TWL cords are hard to beat. Oh Peter time to experiment.

Thought I'd throw in a graphene experience.  I ordered some powder and have been experimenting with it in a solvent.  First application was on interconnects and associated rca jacks.  The result was immediately noticeable... more detail.  Did another set with little effect.  Then I was taking the dog out last night- with a flashlight since rattlers have been an issue this year.  Came in, applied a light coat to the battery and contacts, and went back out with a noticeably brighter flashlight.  It was an obviously better connection that had a real effect on the light output.  Graphene or simply cleaner contacts??? Both??

Sounds like a good application would be the battery terminals for Gary Dodd's battery preamp or buffer if someone has one.

:duh  I'll dope both of mine tomorrow and report back.

When we return from Portland my next task is to build several different graphene doped interconnects.  It will be very interesting.  With the results that I have achieved with graphene so far I expect great things!

I have graphene on the way thanks to Scott.  I have some of the vendors “special” graphene coming and expect very good results!

I love this profession!
