Answer:
HAARP, High Frequency Active Auroral Research Program, does exist. It is a basic research project of the USA (other countries have similar facilities), and conducts fundamental research on the physical and electrical properties of the ionosphere.
The power that HAARP can apply to its transmissions is large. The largest legal AM radio antenna in North America is 50 kilowatts. HARRP operates in the HF (High Frequency) range and its power capability is about 72 times that, at approximately 3,600 kilowatts.
*From time to time the Alaska facility holds Open House events that anyone may attend.
