Fusion, Maybe

As you could have read before you posted that - " It doesn't. Electric arc furnaces are used to melt metal, not to reduce ion oxides to metallic iron."

You can burn fossil carbon to get metallic iron hot enough to melt, but that isn't where most of the coking coal used to make steel from iron ore get used up

Any way the metallurgists like. If you get your soft iron hot enough in a reducing atmosphere and expose it to graphite, the carbon will diffuse through solid iron.

Melt the soft iron - again in a reducing atmosphere - and sprinkle the graphite on the surface, then stir vigorously. Carbon diffuses even faster through liquid iron (which melts at 1538C). Graphite doesn't melt, and is less dense than liquid iron, so you would have to stir vigorously.

What would be done in practice is anybody's guess. Nobody makes industrial quantities of iron by electrolysis at the moment, but metallurgist make all sorts of alloys in all sorts of ways and there's bound to be some approach that would just work.

More likely in gas turbines. Fuel cells would be more efficient, but pushing the original electric power through a long undersea cable and leaving out the hydrogen completely would be roughly three times more efficient. Singapore seems to be close enough to Australia to make this ostensibly feasible. Japan and South Korea are a bit further away.

Yes, I did, that's why I had to ask again as you seem to be going all around the issue but not addressing it.

Ok, so this whole issue is a red herring. Thanks

If it is three times more efficient, what is not "feasible" about it? Are you saying the cable would be enormous? What are you saying exactly?

Here's one, July 4 2011 at Sugar Bowl.

Aspen once had a streaking fad. One day the entire ski patrol made their last run down the mountain naked. The bad news is that it was all guys.

Really?

Thanks for the original contribution.

That's because you didn't know enough to understand the answer.

Your red herring.

It would be very long. It's 3,353 km from Darwin to Singapore.

is currently the world's longest undersea cable - about 720 km long.

Some of our venture capitalist seem to be happy to contemplate a five-fold longer cable. Maybe they are thinking about using high-temperature superconductors, and lots of undersea Stirling cycle refrigerators.

Ok, I guess no one read It. :) Long day....

But at the same time a contrary undertow reels us back into byways of history, sampling the chipped-paint signposts of lost Americas, their bygone Mr. Salteenas and others of his ilk. Ashbery is always in the contemporary world but not quite of it, because he has other worlds to inhabit, or at least to conjure or salvage: the present is just one of the many sectors that make up the historical multiverse of his poems.==James Gibbons reviews John Ashbery's new book, Breezeway
