Just what you've been waiting for: another confusing acronym to add to the jargon of LENR and CF.
HSS is HyperSonicSound. Even the NYT has picked up on it, meaning that it is far from new and bordering on hip - Right Woody (Norris, not Harrelson or Boyd)? http://www.woodynorris.com/Articles/NewYorkTimesMagazine.htm HSS works by putting sound on a carrier wave, much as radio does, but the carrier is ultrasound. In the transmitter, audio frequencies are riding on ultrasonic frequencies as a composite frequency that is inaudible to the human ear unless that ear is a certain distance away. The sound "hitches a ride on the ultrasonic frequency," the inventor says, which travels in a laserlike beam in whatever direction it is pointed. "And here's the beauty part," he says. "The air molecules themselves convert this ultrasonic frequency back down to a frequency that can be heard." So unlike sound that travels on radio waves and has to be converted by your stereo's receiver, you simply need to be standing in the path of an HSS beam in order to hear the sound. Heck, Murphy's dad (Candice, not Law) knew about this kind of sound thing a long time ago, right Charlie (McCarthy, not Brown)? The basic idea may be a gimmick, but what I like about the more general concept is how it relates to Dardik's superwaves, which have a strong relevance to LENR. http://www.lenr-canr.org/acrobat/DardikIintensific.pdf One wonders if HSS has relevance to sonofusion? IOW - Wonder if you would get more neutrons from a sonofusion reactor where the HSS overlay was music, and if so - what type? Classical? Heavy Metal? How about 'The Ride of the Valkyries' (Act III of Die Walküre by Richard Wagner) which is my personal favorite for maximizing payback. As Kilgore sez (Bobby D, not Trout): "I love the smell of napalm in the morning" ...
