Manufacturing Black Holes

This article seems scary to me:

They're going to start (in theory) making black holes.
Granted they are smaller than a proton, but still, how do they know how to control them? The scary part is that they don't.

A black hole and a black ring can co-exist, in theory, as long as they are set spinning, say Henriette Elvang of MIT in Cambridge, US, and Pau Figueras of the University of Barcelona in Spain. "If you just had a ring, it would collapse. It's essential that it rotates to keep balanced," Elvang told New Scientist.

Just like the central black hole, the ring would be defined by its event horizon, a boundary beyond which nothing can escape the object's gravity. The ring could be thin like a rubber band or fat like a doughnut, and the rotation would flatten it – "like a doughnut that you have squashed," says Elvang. The spinning ring would also drag space-time around with it, making the central black hole spin as well.

2 questions:

When will I be able to get myself one?

and

How much will it cost?

In the article they don't seem to believe it will "eat" their surrounding

oh yeah and another question:

How long before they find a military application to it?
