Slaxl: Since black holes emit radiation, a tiny black hole should only last a very short time, not long enough to do any serious harm, so what's the problem? It's not like it'd feed, grow, and start swallowing the Earth.

1) Black holes will have the same mass as the material that was collapsed to create them.

2) Gravitation follows the inverse square law.

3) The reason that regular black holes are difficult to escape is because the mass of the sun (really big) is collapsed to a singularity (really small). So that all of the gravitational strength is concentrated on a tiny little point.

Therefore, if you want to create a black hole that's going to cause trouble here on earth, you need to start with a big mass ... like your mom.

Actually they did. It's under the passenger seat so please don't drop my sunglasses.

FrancoFile: But the micro black hole is portable.  Create the black hole in a fixed facility, drop it in a container, and put the container on a boat/plane/whatever.

If you want a portable energy source, build a battery.  Or a modular nuclear reactor.  Or whatever.  Not a black hole containing a micro-Joule of energy, which will evaporate instantaneously upon its creation, that requires a 5-mile wide, 100-megawatt supercollider to create.
