Peaceful Applications
A 1998 patent describes a device that can scare off birds from wind turbines, aircraft, and other sensitive installations by way of microwave energy pulses. Using frequencies from 1 GHz to about 40 GHz, the warning system generates pulses of milliseconds duration, which are claimed to be sensed by the birds' auditory systems. It is believed this may cause them to veer away from the protected object.

Famous quotes containing the word peaceful:
“A new world is not made simply by trying to forget the old. A new world is made with a new spirit, with new values. Our world may have begun that way, but today it is caricatural. Our world is a world of things.... What we dread most, in the face of the impending débâcle, is that we shall be obliged to give up our gewgaws, our gadgets, all the little comforts that have made us so uncomfortable.... We are not peaceful souls; we are smug, timid, queasy and quakey.”
—Henry Miller (1891–1980)
