RE: Air Force Turns 747 Into Holster for Giant Laser (washingtonp ost.com)
by Trei, Peter 23 Jul '01

23 Jul '01

With high-powered lasers, one of the important destructive mechanisms is blast - the outer layer of the illuminated object vaporizes, and flies away from the rest of the target. The reactive force of this gives the target a hell of a kick. Kicking off strict alignment with it's flight path, or putting a big dent (or even better a hole) in the side of a missile under several G's of stress traveling at a high Mach number is not healthy for the missile. Laser's have problems though - as they heat the air the refractive index changes, leading to 'blooming' or beam expansion. At too high a power density they can also ionize the air, which makes it effectively opaque. Dust, haze, and clouds are also problems. Using *very* short pulses eliminates many of these problems.

Re: NetCurrents: Echelon for the Private Sector,

About the "no expectation of privacy in a public place" angle: do you really think two people talking solely to each other on IRC expect their throwaway comments to be monitored, logged, and made part of some lame marketing presentation? Once people know the technical capacity is there for that to happen, that's one thing. But otherwise it hardly seems right. > On Sun, Jul 22, 2001 at 05:15:53PM -0400, Faustine wrote: > > Did you know that NetCurrents, which bills itself as "the Internet's > > Premiere Intelligence Agency", conducts real-time monitoring of message > > boards, chatrooms, and IRC channels, logging and producing reports on all > > occurences of particluar keywords for their clients? > > > > Echelon for the private sector, pure and simple.

Of course you're right, no one can expect to be handed privacy on a platter. How do you feel about web bugs and cookies--if it's part of the private sector, anything goes? I don't think legislation is the answer--educating people so they can take care of themselves makes sense to me. Hence my two cents about Private- sector Echelon. ~Faustine.

The reactive force of this You're orders of magnitude away from such fluxes. You're trying to hit a moving, rapidly accelerating (possibly flying random evasion maneuvres) high-albedo vehicle -- through the Mach cone, through the 100 km of atmosphere filled with clouds, haze, random fluctuations, etc. Once it's past boost phase, it's essentially invulnerable. Chemical lasers have a limited numbers of shots, every energy leaving the vehicle must pass through it's optics aperture (which must be damn transparent). The vehicle is very complicated and delicate, and expensive. Given that you have to make many kills during few 100 s window, it doesn't appear cost-effective. If it's in LEO, I just launch a bucket of tungsten or depleted uranium birdshot in countersense orbit. Given a few iterations, I can keep surprising amounts of orbital space clean of any operable machinery. > gives the target a hell of a kick.
