I think you are a bit confused, in a dipole all the field lines emerge at one end and terminate at the other end. The exact shape of the field lines depends only on the shape of the magnet or electric dipole, in principle any magnetic dipole configuration can be exactly reproduced with an electric dipole and vice versa.
http://en.wikipedia.org/wiki/Dipole
compare the diagrams of an electric and magnetic dipole field. One of these is not like the other, it's easier to see in diagram then my attempt to describe in words.
If you make an electric dipole by charging opposite ends of a conductor, then you will get zero field inside the conductor...
While the field lines of a magnetic dipole look almost like an electric dipole from a distance, they differ significantly in behavior close to the source. Externally the lines point out of the positive side and into the negative. Internally an electric dipole's field lines point back from the positive end to the negative end, whereas in a magnet or solenoid the lines continue from the negative to positive.
If you tried to build this device with an electric monopole, it would lose energy while passing the dipole, for a net energy of zero. But a monopole would experience its greatest acceleration while passing the dipole (you'd want to design it like it's passing inside, with magnets on three sides).
A magnetic monopole would be attracted to one end of a magnet and repulsed by the other. So you could set up a wheel with identical magnetic monopoles on the edge and a magnet parallel to that edge, and the wheel would accelerate indefinitely.
Unlike an electric motor no energy would be required, it would be better than a perpetual machine, it would be a free energy machine.
This of course would violate conservation of energy, which for me indicates that an isolated monopole is impossible.
The book "Dragon's Egg" about life on a white dwarf, had some interesting applications of monopoles. They were used by human explorers to counteract the intense gravity and get close enough to study the star (from orbit). Personally I doubt they exist, but I'm sure very surprising and useful applications could be found.
Exactly. I worked on doppler radar algorithms at UCAR some years back, and targeted de-noising works pretty well. We'd identify and subtract out bugs, birds, airplanes, weird atmospheric reflections, and barns. Barns were pretty easy; you know right where they are, they have a big predictable amplitude, and no doppler shift. Turbines can't be that much harder.
For example with 3D electron microscopy. It requires multiple copies of the same molecule on a chilled plate, take a progressive electron microscopy scan of the plate, and the 3D image is reconstructed from the multiple images. Individual atoms can often be identified by relative size. It's been awhile since I've looked at this but I can only assume the field has progressed since then.

They don't really discuss the social/legal implications the news reports do, they do point out that it's a very limited study (18 sociopaths). The data looks pretty good, but I've seen small promising studies like this all the time that turn out to be an unrepeatable fluke.

You're thinking of a diode, not a capacitor.
Look at the title

Not a bad book, but its discussion on magnetic monopoles is hardly conclusive.

Gravity only attracts, the magnetic monopoles would be kept in motion because there is a repulsive force.
That equation comes from empirical evidence and can be removed without breaking anything.
It would break the empirical evidence... And I think you mean extra "term".
There's nothing trollish here. At the least it's an honest counterarguement, and worth replying to rather than burying.
Yup I don't buy it either. They probably address your question in the paper, but it appears they do so by tweaking the definition.

That's a good personal defensive move and good for your taxes, but doesn't protect your product from trolls and infringers.

And the judge upheld the damages against SCO. Sounds like he agrees with the conclusion, just feel it should have been done more carefully.

This sounds a lot like the set-up for Terry Gillian's "Brazil".
