HAARP (spell the acronym correctly) uses microwaves to
heat the ionosphere. Your foaming at the mouth about its uses has
only the vaguest connection to reality. It has nothing to do with
efficient transmission of power by low frequency waves (indeed,
any ELF it produces by heating of the ionosphere will be nine orders
of magnitude weaker than earth's background ELF.) It cannot modify
or control the weather; it can barely affect a limited region of the
ionosphere (with effects much weaker than natural variability there.)
