I gave 1x 2oz copper coin with Abe Lincoln to friendly Brazilian butcher, just like that, casue I like the meat and talking to him. 2 weeks later I came back and he gave me 2kg of good Irish beef for free.
Today I gave 2oz copper to my friend as a gift , to conclude discussion about money printing and men of known origin behind it. 20 mins later I received ... baby car seat ,I took a picture and send to my wife , she said 'this looks exactly like what we need'.
Now I feel obliged as both gifts I received were way more expensive, so they will be getting silver coins soon. All started with copper ...
A few people showed Jeff Currie saying copper is a better conductor than silver. I googled the topic and ALL links indicated silver is better. Unless Currie is quoting recent scientific news, he's lying. I don't have the time to listen to his interview right now. While it's true copper is cheaper, perhaps the difference in conductivity levels makes it unwise for entities to use copper.
I don't know how to use redstone
I was looking up different verification tests and it said copper can pass for silver on a ECM test, which for me it is hard to imagine that copper would be not viable as a substitute for most applications requiring high conductivity.
Look at the following report by Chris Marcus on Silverdoctors.com

I know…I know….you thought it was silver….
PUR made a very good announcement and is in the right spot.
Next resistance is 0.061 then 0.073 then 0.083
currently trading at 0.049
I was studying batteries more deeply and I found them really really cool.
drawing source: The Engineering Mindset
One thing I thought was strange is that we use brass in the inside nail of the batteries that forms the negative terminal, brass is only 26% as conductive as copper.
I think it has to do with some other characteristics of the material, like these for example (source):
>While copper is more commonly used for standard electrical applications, there are situations when brass is the preferred material due to its high tensile strength, resistance to corrosion or other properties.
But why on a battery? Would they be that more fragile if we would use copper instead of brass? Would we notice the advantages of using copper? Do we use brass because it is cheaper, or maybe because at such low voltages the material conductivity itself doesn't really matter?
Why do we use brass instead of copper?
Hello Everyone. If you don't already know, Composite Fiber Optical Cables are cables with both Fiber optical strands and copper conductors within them. This allows you to power equipment and exchange data up to 2000 feet away from the device, as opposed to the 100 meter limit of regular Ethernet cables. Also, normal Fiber Optical Cables don't have the ability to power devices at all, whereas with either PoE or these you can. So my questions are:
Have any of you people ever used Composite Fiber Optical cables? If so, what are your experiences with them? If not, are there any application where you think they would be useful in?
