IT IS the year 1868, the scene a tranquil valley in Donegal, Ireland. A man is tramping across the peat bogs. Glancing skywards, he sees a storm brewing on the horizon and decides to head for home.

As he retraces his steps, something makes him turn around, and he sees the strangest sight of his life. A bright red glowing orb half a metre across is floating down a nearby hillside. It bobs over the valley, then vanishes near a stream. No sound, no fire, no explosion - yet the ground beneath the red sphere's path has been churned up and torn to pieces.
“The glowing red orb left a square hole about 6 metres wide and ploughed up a 100-metre trench”

Cut to 2004, when a US government physicist finds a report of the incident, now gathering dust in the British Library in London. Though he has seen similar reports of ball lightning, there's something very odd about this one. Bit by bit, he comes to the conclusion that the glowing apparition has the hallmarks of something literally out of this world - an ancient black hole.

I will admit that reading the link to the IEEE report was way over my head. But I found it interesting. Something happened, a very long time ago... maybe 30 years ago? that I have never told a soul about.

My father was running for county coroner and liked to use the "family man" angle. He took my sister and I to many different functions around the county. One night - I think I was 10 or 12 years old, we had been to 2 different pancake suppers at local churches. On our way home - this very odd flash of green light appeared about a half a mile in front of our car. My dad and I saw it and it tried to follow it for miles - we saw it flash 2 more times.

I never thought it was extraterresterial... but I couldnt explain it either. As far as I know, my father never told anyone else about it either. But it was very odd and now... this might explalin what it was!!

So, if his theory is correct, he wants to capture one and use it to generate power. Interesting stuff!

Could be useful.

For a bit of science fiction related to mini black holes try Artifact (http://www.amazon.com/Artifact-Gregory-Benford/dp/1841490628/sr=1-22/qid=1167139234/ref=sr_1_22/102-6484468-1032936?ie=UTF8&s=books).
Not to be confused with The Artifact (http://www.amazon.com/Artifact-Daw-Book-Collectors/dp/0886774063/sr=1-6/qid=1167139119/ref=sr_1_6/102-6484468-1032936?ie=UTF8&s=books) which I also enjoyed.
