HAARP is an acronym that stands for High-frequency Active Auroral Research Program. Its official purpose is to study the ionosphere and its main installations are in Alaska, though other facilities are involved, too.
Most researchers agree that the official programme is just a cover for a wide range of other experiments. Experts point out that the technology that is being used in the HAARP project can also be used as a weather manipulation device, or as a ground based "star wars" weapon (SDI), based on Nikola Tesla's Death Ray. The technology is also well suited for mind control experiments - more specifically, the production of intercranial audio phenomena (i.e. hearing voices inside one's head) - as well as for the manipulation of space and time.
As outlandish as some of these claims may seem, there actually is a lot of material to corroborate them.
