Large Hadron Collider

Product unknown
Product units per year is also unknown
Very expensive to build
Slight chance of causing a global level three disaster event.

Raw materials include liquid helium, superconducting magnets, and fiber optic networks each requiring their own production plants. Largest consumptions would probably be electricity and internet.

New occupation of quantum physicist (= +/- 100 university lecturers)

Largest consumptions would probably include computers as well as coolant. LOTS of coolant.
As well, now that I think about it, lots of Books and Magazines (especially the "special" ones) + lube cream, for the time you're waiting for the ions to do the equivalent round trip to Pluto.

That's marvellous news to me.

I possess the monopoly on the lube market.
