Make elements? Dave's into alchemy now?

[John_ITIC]

Apparently, heavier elements such as Copper (atomic number 29) needed the massive heat from large supernovae to be created:

They say most of the elements come from the stars and, consequently, we are all made of star dust...

Same here.  If I was an Australian I would use YTD Video Downloader to download it and the reupload it for the everyone else, but that's just me.

Nothing I see with a 9:46 time or close, nothing looks like this video.  Link?

Use the Teslacoil link to the whole video.

I can watch around half the Smithsonian channel videos, but others are " not viewable in your country, sorry about that", so YMMV.

I put "How It's Made-Copper" into Youtube and the result page doesn't have this video and it has no reference to "Teslacoil".  Neither does this thread other than your mention of it a few seconds ago.   I am still not findit it.  Link?

The link is a few posts above in this thread...

Now that was an interesting story put together by a few members, thanks guys!

Great video! 
Slightly annoyed by the black smudge on the bottom right though...

So how much energy is needed to make 1kg of copper?
And wow, so much scope for environmental damage if things are not done properly.

So how much energy is needed to make 1kg of copper?

Wild back of the envelope order-of-magnitude guestimate without looking anything up: 100kWh. That's based on 250eV per copper atom (allowing for the huge inefficiency of the whole process, but perhaps I'm still being conservative).

And wow, so much scope for environmental damage if things are not done properly.

In terms of raw energy cost, aluminium is a lot more damaging AFAIK. Australia is one of the main producers and exporters of Al ore, and all the Aussie Al production is powered by the dirtiest modern fuel, coal. The bulk of our Al ore export is to China and that fares no better (we also export coal to be burnt in China).

Conservative by a few orders of magnitude!  Aluminum doesn't even cost 10eV/atom, and it's electrolytically smelted!

It's a lot more than that for sure. Not talking about just the energetics of the chemistry but the actual energy cost per atom from mining through to you having a piece of aluminium ready to use in your hands.

I think this is the same power plant in the UK...

i am guessing it is under historical conservation?

Correct. It is not allowed to knock it down.

All very interesting, but they seem to have forgotten the last stage: "Critical listening", where "experts" deduce in which direction the electrons flow best?
