Actually, Hammerite posted a thread on this a few weeks back.
I read the theory, and posted the following:
Hmmm... It is an interesting article I will say. It seems to be a modified version of a theory floated around the turn of the century though. At the
time, heat measurements were being used in crustal cooling calculations to determine the true age of the planet, and they were coming up with
incredibly young ages, as young as 2000-3000 years. These discrepancies were explained as a layer of radiactive isotopes existing at the bottom of the
crust/top of the upper mantel (supported by the statement in the article that the radioactives readily bond with silicates, which are the main
constituent of the crust/mantel) were decaying, releasing heat at a much higher rate than released by the core.
The other problem I see with this is that we currently have no evidence or proven mechanism for the direct conversion of charged particles/radiation
into a magnetic field. The current theory holds that the magnetic field is created by slow movement of the inner mantle around the core, basically as
a giant dynamo or generator, forming electrical induction through the physical movement.
It is interesting though, and I would be interested if he comes up with more evidence.

I have to say that there isnt a hell of a lot of evidence to support this other than a couple of (granted interesting) computer simulations. I
certainly am not going to loose a great deal of sleep over whether our core is about to run out of steam or melt down in the immediate future.
