Well, HAARP directs RF energy skyward using an array of antennas for research and isn't exactly a secret.
The DESTINY project in the movie was a secret and it sucked energy up from the entire grid and somehow shot it to the center of the planet in an attempt to ...trigger earthquakes?
How they were going to aim DESTINY is lost to plot holes.
Being able to say that the Earth's core stopped just like what happened in the movie makes the earthquake machine theory more plausible or something.
