What they needed it for was a collection of calutrons, to be built at Oak Ridge.

The calutron was the idea of Ernest Lawrence (Lawrence Livermore and Berkeley laboratories are named after him.)
Around 1930, Lawrence had invented the cyclotron; the calutron, and an adaptation of his machine, was capable of separating U235 from U238, one atom at a time! Essentially, it was a mass spectrometer.

The machines needed magnets, really BIG magnets, and the magnets had to be as powerful and efficient as possible. Thus, the silver from Fort Knox.

Ridiculously expensive to build and to operate, the calutron
was one of several approaches to uranium separation, which were tried all at once.

After the war, they sent the silver back to Fort Knox.

Bump.

Next on the agenda: Terahurtz processors..

We’re computin’ now, baby!

There’s an article in the new “Scientific American” about graphene.

Ah, then, perhaps, we’ll have a processor that can run Vista...

Will need a Terabyte of RAM in ADDITION to the Treahurtz processor to run Vista. BLOATED code
