good explanation bruce !

one of the reasons TNT became the product of choice over other
explosives such as nitro. Easy to transport and very stable

http://mooni.fccj.org/~ethall/explode/explode.htm

Trinitrotoluene is a high explosive that is
unaffected by ordinary shocks and
therefore must be set off by a detonator. TNT
is often mixed with other
explosives such as ammonium nitrate to form
amatol. Because it is insensitive to
shock and must be exploded with a detonator,
it is the most favored explosive
used in munitions and construction.
Why do nitro groups (NO2) lead to unstable
compounds?
Nitrogen has charge of +1 and nitro group have
a strong tendency to withdraw
(pull) electrons from other parts of the
compound. Attaching three nitro groups to
a compound leads to an extremely unstable
situation.

Eventually, they might be combusted, but not as part of
the detonation. So, their combustion energy contribution
isn't counted as part of the explosion.

The above is just plain NONSENSE. When TNT Detonates, it is the
detonation wave front that causes the cyclic ring of tolulene to
break and release the bonding energy of the molecule. The detonation
wave front is traveling faster than the the molecules can move on their
own, so they don't move, they just get slammed by the detonation wave.
There is a GIANT difference between combustion and detonation. TNT
does NOT combust when it decomposes in a detonation.

I share this skepticism. Burning TNT probably would produce 10x more

When you detonate it, what happens to the 90% lost energy?
Fails to actually detonate?

First, tell me how one "burns TNT". It is a high explosive. I
think its "burn rate" would be pretty fast, and not manageable.

That guy's empty skull cavity has a lot of free space in it.

Why do you feel it necessary to abuse everyone with whom you disagree?
especially as the half-dozen or so posts below clearly indicate that you are
WRONG.

If one arranged the TNT into a fuse, how fast would it burn?

Depends on whether you ignite it (Zippo, etc.) -moderate speed for a fuse-
or detonate it (initiator, blasting cap, etc.) -very fast... think

Unil the terrorists get nukes, then there will be no Jerusalem.
It is as predictable as a TTL timer, only one outcome possible.
It is probably far to late for Israel to change that outcome.

Jerusalem is probably the only city in the region that _isn't_ a potential
nuke target. Too many sites sacred to both sides.

a dirty nuke wouldn't physically damage any sacred sites. just contaminate the
area for thousands of years so no one could live there.

But everyone knows that if Jerusalem goes, Mecca, Medina, Teheran,

When I look at hthis statement closer, you see that now we have

pushing Iran, the currwent CIA operations in Siria, everytime the balance
for a Israeli targets for a 'strike back' decreases.
Lowwer threshold.
People who have nothing to lose do NOT go by any rules.
IMO Bush Jr want, before he leaves offcide, a worldwide fire started.
This to help his weaopon producing friends.
Same as Vietnam was for no reason at all....
So he may light middle east, China Taiwan, or both, or something else.
Here is a mirror for the US.
Its ugly.
But on the other hand, humanity has always been that way.
The beauty in it is it makes the species strong, PROVIDED there are

But it would be more beautiful if people could live in peace.
We do have, as humans, a brain that alows us to view the world from

Their lives are still important to most of them, the number who become
suicidal over political causes is actually rather small. If we simply
blew the **** out of whatever family home and neighborhood that the
latest suicide bomber came from, these attacks would stop. Most of
the allure to brainwashing kids to carry bombs is lost when their folks
contemplate retaliation directly upon their own head. The Russians
have learned how to deal with Arabs, ask them! Promising and then
carrying out the napalming of errant neighborhoods without any
apology whatsoever would end this in nothing flat. There's absolutely
nothing whatsoever wrong with genocide if it is not intended as such,
as with the Nazi's, but incidental to the purpose, as with Eisenhower.
Always make it strictly conditional, if you do this, we will do more
of that, and we will always escalate ten-fold and upon civilians!!!
A people is utterly responsible for those who lead and represent them
and how they do so, even down to their very children!

Agreed, Bush at alia, but there are many others who know better,
which was how Vietnam stopped. On the other hand, we need weapons,
we simply need to use them a bit differently.

Nawh, I don't buy it, our nature depends far more on culture now
than genetics. It doesn't matter whether a suicide bomber is
a congenital idiot.

It requires, firstly, that we either do away with, or terrify any
who would breach the peace of the world. That requires an ugly but
actually very civilized demeanor, one that will not tolerate disorder
and will not bother apologizing to anyone.

People are not perfected by appealing to them, they are perfected by
their neighbors not tolerating their deviant abusive bull**** anymore.

When they finally always get it worse than they give, they ****ing
stop, and not until!

Ships around the turn of the 20th century transmitted morse code by
spark, I think.

The Lusitania, Mauritania, Titanic, and Olypic all ran on coal. No
gasoline in sight. Later vessels ran on bunker C fuel oil, which is
more like tar than gasoline. I don't think one has to worry about
sparks on such a vessel unless it's finely devided coal dust, which
finished off the Lusitania in a secondary explosion after the torpedo.

Interesting idea. I would have thought that a tube would require
more V than a neon lamp to get started. I'll try it if I can
find a lamp.

Neon lamp needs about 60 volts to light and 40 volts to stay lit. The
4 watt flourescent tube wants at least 90 volts to start, and I think
(i.e. guess) about 50 volts to stay lit.

What you seem to be suggesting is that I simply connect the
lamp to the 1/4 wave receiving antenna, right? Why introduce
my hand? For ground on the other lamp contact?

Yep. You're the ground. You should be fine with a 5 watt CB and a 1/4
wave whip. The high voltage point is near the tip. However, don't
try it with an illegal CB linear. You'll get an RF burn for your
troubles.

Incidentally, there are cell phone antennas with lights in them.
http://cellphones-accessories.com/12stobligcel.html
They're LED's which require much less power to light than a 4 watt
flourescent bulb. Still, it's kinda interesting.

I don't see the point of attaching a long
wire to the CB, because they don't come with long bare wires.
Clearly, I could get a good spark by attaching a wire to the
CB batteries, and avoid all the RF stuff!

Exactly. Same with an open relay contact or toggle switch. However,
don't foget that you need containment to create an explosion.
Sparking the DC inside the trunk is the mostly likely location.

22 V is a lot more than I could get with a 1 m monopole: I only
got 100 mV peak to peak.

The 22 volts peak is at the RF connector. I'm assuming that if there
is a spark gap, it will be in the coax cable or associated antenna
connectors.
...

I finally got hold of a 4 W fluorescent lamp (Coleman 12V lantern
replacement; H-F4T5D(3)). I attached a 2.7 m bare copper
wire to one end of it and tried holding the other end
in my hand while keying on Channel 40. No obvious effect.
