| abbr., mil. | High-Frequency Active Auroral Research Program | HAARP (На Аляске по программе ХАРП в 1995 г. была построена специальная станция. На площади в 15 га возведено 48 антенн высотой 24 м каждая.С их помощью сконцентрированным пучком волн и разогревается участок ионосферы. В результате образуется плазмоид. А с помощью управляемого плазмоида можно влиять на погоду - вызывать тропические ливни, будить ураганы, землетрясения, поднимать цунами; ХАРП ВВладимир) |
