Yeah - it's far more complex, and iron != steel.

(The article talks almost entirely about steel (vs. iron), but is too detail-fuzzed to trust that.)

I made very charitable assumption from this:

> Ultimately, the company hopes to license its technology to steelmakers.

Actual steelmakers know all the myriad costs and details and steps required to make steel - and would probably prefer that any radical new process replace as many of those step and details as possible, at an economic cost.
