10 technologies that refuse to die

I was thinking **lightning**
and the inherent relative resilience that vacuum tubes have to it
(and to EMP, as was mentioned in the article),
but feel free not to RTFA and to not make the connection.

BTW, the big runup in amplifier power ratings after the introduction
of transistors was due to a feedback between speaker and amplifier
design. Cheap audio power allowed speaker designers to pay less
attention to efficiency, so the next generation of speakers required a
new round of bigger amps. Fortunately, the law of diminishing returns
kicked in before we had to start ordering three-phase power service
for our audio systems (and for the extra air conditioning to get rid
of all that heat).

Well, there ARE still people who get dedicated 3-phase power service
for their audio equipment... *shakes head*

Indeed I DID read the article, but EMP is bogus, any device that
generates sufficient EMP at a distance to destroy solid state
also blows it to hell in the process at that same distance!!
This comes out of energy densities and classical radiation
exchange by black bodies.

Nothing wrong with tubes, except thinking they are linear/sound good!
As an easily fabricated medieval switching device they're fine.

They work well on live Bass guitar rigs.

Not much else.

Oh... they work well in transmitters. We are doing a 25kW RF
project soon.

I got a good laugh the last time I picked up a copy of "Stereo Review"

pretentious twits claimed that they could hear the difference between
oxygen-free high-conductivity copper and silver-plated OFHC, or
twisted-pair and coax cable, or plain stranded and litz cable, ad

The silly thing is that even if some of this stuff DID do wonders for
the purity of sound, from a technical aspect, we won't know it till
we design ourselves some new bodies and brains with a decent set of
ears, so that we can hear worth a damn!!

Even now, our technology is pouring pearls out before our swine-like
pitifully evolved senses.

I worked at a place that used all stainless for medical equipment
and environmental chambers.

They used ROC made zinc plated 1/4" - 20 x 3/4" cap screws that were
SUPPOSED to be grade 6.

They twisted off like taffy, and I was persecuted for bringing it to
their attention.

Who's toes did I step on? Quality sucks because some "trained"
folk don't recognize what it *IS*.

I got a retard in one group telling me that an inductive current
probe is more accurate than a simple current shunt resistor and a
voltmeter. Imagine that.

Actually we use them for high power only because they're cheap when
compared to the cost of silicon alternatives to klystrons.

They STILL need the shit compensated out of them for lousy response
above low audio!!

Funny how they're ALWAYS "in development" and have BEEN so for more
than 30 YEARS! Sort of like other Tesla-fanatic inventions. The simple
fact is that you can focus a shitload of RF at something with a dish,
but it falls off faster than 1/r^2 because it's subject to HUGE f-stop
aperture considerations unless the dish is enormous, requires a LOT
MORE energy than merely blowing the hell out of it with a shell or
missile, or even a huge blast-in-range, and can be deflected with 30
cents worth of Aluminum foil or Aluminum paint inside cheap plastic.

Otherwise you're talking solely about ranges of a few feet because
you want specifically to target electronics, instead than merely
blowing out the tires.

Even a maser is subject to reflection, and really BIG EMP weapons
are merely explosives which are better used ballistically.

25kW even through Eimacs is not cheap. Doing it with silicon is not
only not cost effective, but it would take up more cabinet as well.

Thermal abatement issues are more of a problem as well.

We were recently contacted by a contractor for a unit similar to cap
chargers we make.

They are not even allowed to give us details. This project is
actually showing promise. Not a true EMP, it is more like a directed
mw beam or such.

You can bet they are serious about it. Being able to electronically
disable an enemy does far more than cripple them from movement. It
cripples their ability to call in for help as well.

An army with such devices could easily cut off groups of enemies
from their support lines. This is a good thing.

They made far more progress punching dents into missile shells with
eximer lasers from great distances. Pretty wild shit, but not
portable at all.

No. You are not hip because you jump into forums with no regard for

Ever heard that top posting is a bad thing. Well, in Usenet, it is.

Bone up on usenet.

Yeah. On their POS $300.00 receivers.

It takes a $25k audio front end to even be able to *SEE* the
difference on a scope, much less *hear* it on the monitors.

Came up fine on mine after 4 blank page "done" no shows like that
which you describe.

Go to msn directly yourself, then click the link while your page has
already accessed their ssl sockets.

I have Firebird.

My seti page won't pop up directly from a link sometimes either. I
have to click up the home page, then click my link. Only happens on
their ssl server links. For me. It's probably Bill's fault, and not
something that msn differentiates based on your browser as I have
encountered it at other than MS sites.

I have to agree, the worst thing about it is that as soon as you hire your
car you are really thrown in at the deep end and it's frantic until you get
out the other end of the Sumner tunnel where they extract money off you for
the privalege of being stressed.
