I am not sure about this one comment in the article submitted by OP. As far as I understand the temperature at the center of the earth should be as high as that of the Sun. The core is known to be the heaviest and hottest part of our planet.

I think the most recent estimates have the core temperature of the Earth at about the surface temperature of the Sun, plus or minus a few hundred kelvin. (In the neighborhood of 6000K)
The core temperature of the sun, and the temperatures expected in the reactor described, are several orders of magnitude hotter, on the order of 10^7 K.
The temperature of the Earth's core is about the same as the temperature of the Sun's surface: a mere few thousand Kelvin. Not much hotter than the tungsten filament in an incandescent light bulb. The Sun's core is some 30000 times hotter, and the plasma in a Tokamak type fusion reactor about ten times hotter still.
