Yes I also wondered if this occurred in black holes, but of course we can't find out .... well not safely, or communicably! If these energies don't occur in SN etc then I certainly don't see us producing them in the near future. I only guessed SN because Hawking said we'd need an accelerator "larger than Earth" which doesn't sound THAT unfeasible for something that might occur naturally (like those giant space lasers). Of course he didn't say how much larger! Maybe he meant "larger than the solar system" or the galaxy, which of course makes a natural equivalent seem a lot less likely.
