Not sure I believe much of what Jerry E. Smith writes about HAARP...
He is a poet and author--not an engineer or physicist.
He, appears, to also misplace 3 zeros in his article. Early in the article he talks about 960 kWatts for the initial tests, and 3.6 million watts (3,600 kWatts) for the final output. And 3.6 billion watts!!!!!!!!
He also talks about ERP (Effective Radiated Power)... You can get "more power" out of an antenna array compared to an "ideal" spherical radiator by directing the power one direction. For example, an FM Radio station may have 50-100,000 watts of ERP, but only use a 10-20,000 transmitter to generate this power (radio station has no need to broadcast any power straight up into space or deep under ground--few people to receive those signals).
I am not sure quite sure that he is very consistent in use of terms and units.
HAARP give the antenna gain as ~20-30 db gain (100 to 1,000x power gain by focusing upwards)--so, that is probably were he is getting the 3.6 Billion Watts ERP (3.6 MW x 1,000 = 3.6 GW ERP or 3.6 billion watts ERP).
3.6 MW is only the equivalent of ~5,000 horsepower (they actually use 10 MW worth of diesel generators to make up for linear amplifier transmitter's losses).
As an example, a 747 can generate about 85,000 horsepower of thrust at cruise altitude--but because it only uses about 1/4 thrust at cruise, it is ticking along on about 20,000 hp. Or, 1 plane is stirring/heating the upper atmosphere for the equivalent of 4 HAARP installations (of course, HAARP is affecting the atmosphere much closer to space).
The HAARP FAQs are here:

I see "black helicopters" written all over this (not to say that there are not military uses for HAARP)--but I don't see any catastrophic issues happening from HAARP. Natural effects by Sun/Earth interactions are going to swamp any effects of HAARP (IMHO). The FAQ also states this too (they have to wait for "quite periods" in the upper atmosphere to even run tests)...
