That article was pretty informative but included some disinformation on HAARPS effects on the ionosphere.

here's what they said:

The intensity of the HF signal in the ionosphere is less than 3 microwatts per cm2, tens of thousands of times less than the Sun's natural electromagnetic radiation reaching the earth and hundreds of times less than even the normal random variations in intensity of the Sun's natural ultraviolet (UV) energy which creates the ionosphere.

That is true in one sense, but very misleading.
The effects of all Scalar weapons are not due directly to the HF signal. The signal is just the trigger.

Just as the effects of a nuclear bomb are not caused by the energy of the small explosive charge that sets the bomb off, but by the energy of the resulting nuclear chain reaction,
Likewise,
The effects of Scalar Weapons are not caused by the relatively small amount of pulsed EM energy used to set them off, but by the "Scalar reaction" of non-linear processes that result.

What are "nonlinear" processes? This relates to the idea of a small input of additional energy creating a disproportionally larger output of energy.

A research scientist, Al Zielinski, explains:

Experiment #1
Imagine we had an unlimited amount of dominoes and we lined them up from here to, let's say, Paris. Then we could tip the first domino with 10 grams; it will fall down and cause the second domino to tumble, too, etc. The first action of 10 grams will cause all the dominoes to tumble including the last domino in Paris.

From this experiment we should understand that it is not the 10 gram action that causes all the dominoes to tumble, but the 10 gram action just creates an imbalance of the first domino. It is gravity that causes the dominoes to fall. In other words: only a 10 gram action is required to trigger a gravitational activity of all our dominoes from here to Paris. This would involve hundreds of tons of effect from an initial cause of 10 grams.

Experiment #2
Imagine we had an unlimited amount of special dominoes of which only the first one is of normal size, and all the subsequent dominoes are of continuously increased size. By the time we reached Paris, the last domino block would be 1000 meters high and weigh millions of tons. Again we tip the first domino here with 10 grams, which will fall down causing all the subsequent dominoes to tumble. By the time the gravitational action reaches Paris, the last domino in Paris will smash the Eiffel Tower.

From this experiment we should understand that it is not the 10 gram action here that will smash the Eiffel Tower in Paris, but it is the gravitational energy that is picked up on the way to Paris that smashes the Eiffel Tower.

In other words: only a 10 gram action is required to trigger a non-linear gravitational activity which will cause the destruction of the Eiffel Tower.

With the above examples in mind imagine the nonlinear effects of 1 billion watts of effective radiated power being directed at the ionosphere by the HAARP transmitter. This is the first phase capability of the project. The second phase will increase the effective radiated power levels even further -- to 4.7 billion watts! In our book we point out that energy in certain frequencies when reaching the outermost portions of the ionosphere can be amplified up to 1000 times by natural processes. This phenomena has been recorded by scientists at UCLA who have observed the results of these power amplifications at a fraction of the power level which HAARP will transfer to this region. This is extremely important in considering what may occur with this level of energy. A serious environmental disaster may well be the result.
