The link is to yet another arXiv paper, this one only a few days old, about creating mini black holes at the LHC at CERN.
The bad news: the paper uses the cautious sounding words:
Once produced, the black holes may undergo an evaporation process (my emphasis).
Maybe that wasn't intentional; it seems that there are extremely few physicists who are prepared to even consider doubts that a few have expressed as to whether Hawking Radiation (HR) exists at all.
For the good news: as I have noted before, some believe that the HR process may leave a "black hole remnant". I haven't noticed anyone talking much about them, and my concern remains whether there is any concieveable risk from them. However, this paper suggests a surprising possible use if such things exist:
If stable BHRs really exist one could not only study them with various experimental setups but also use them as catalyzers to capture and convert, in accordance with E = mc2, high intensity beams of low energy baryons (p,n, nuclei), of mass ∼ 1AGeV, into photonic, leptonic and light mesonic Hawking radiation, thus serving as a source of energy with 90% efficiency (as only neutrinos and gravitons would escape
the detector/reactor). If BHRs (Stable Remnants) are made available by the LHC or the NLC and can be used to convert mass in energy, then the total 2050 yearly world energy consumption of roughly 10 (to the power of) 21 Joules can be covered by just ∼ 10 tons of arbitrary material, converted to radiation by the Hawking process via m = E/c2 = 1021J/(3·108m/s)2 = 104.
By the way, that figure for the total energy requirements for earth is 10 to the power of 21; I have trouble showing such scripts here.
So, if I read this right, they are saying that use of black hole remnants means conversion of about 10 tonnes of dirt could power the entire world. Neat.
Remember, you read it here first.
