   Ah yes.  This machine is called an "electric chair" if applied to
prison inmates, and in that case it is actually legal in some parts of
the US, but no place else in the world.  In keeping with the reversal,
it does not diagnose, but does cure, all diseases.

   If the machine is used *outside* a prison, it is called a "Boob
Machine" (though not to be confused with the women's chest exercisers
sold in the backs of comic books).  It does not supply power, but
rather is used mainly to drain or lower the amount of economic "energy"
or power (Chi), of the applicant.  It cannot treat, but can diagnose
any disease (though none accurately, unfortunately).  Like the machine
in prisons, it can be lethal.  A real doctor always examines the
applicant within minutes after the use of the prison machine, but the
danger with the lower-power device used outside prisons is conversely
that a real doctor might not examine the person at all for quite a
while while the machine is being used (months, years...).  This,
because real doctors are repelled by the special field emitted by such
low-power devices, which causes them to experience acute nausea,
occulogyria, and attacks of sarcasm.

   Hope this is helpful.

The problem is that you can't reliably kill anybody with 20 J of
electricity, so your ratio changes depending on luck or chance.  For
example: your standard electric chair delivers 2000 Volts A.C. for
about 10 sec, followed by 500 V for maybe 120 seconds.  You figure a
body resistance between two patches of moist broken down (fried) skin
of 200 ohms (a realistic figure), and that gives you [(2000^2/200)* 10
sec] + [(500^2/200) * 120 sec] = 350,000 J.  And it doesn't always work
on the first charge, at that.

Yes, probably they could do better in the "chair" with a short shock
through the head to induce unconsciouness (as is done now), followed by
a short shock from front of the chest to back, across the heart, to
induce fibrillation.  But the thing was standardized long ago, and the
judicial system is nothing if not conservative.

If you insist on minimal energies, there are more efficient
applications even than electricity.  How much mechanical work in Joules
does it take to slice into a carotid or femoral artery with a really
good scalpel, or really sharp large bore needle?

    Yep.  The current world record for a healthy person is a seaman
electrocuted standing in saltwater by a 32 volt DC submarine battery.
And of course, it generally takes a lot more voltage than that.   And
AC is more dangerous than DC.  You might be able to do it with AC and
10 volts, but you'd have to have paddles in dirrect contact with the
heart.

    Of course, it's not the voltage that kills, but the current.  The
two are related for the same skin resistance, but there are ways of
minimizing resistance. You can use saltwater contacts.  You CAN also
get much more lethal voltages by abraiding the skin, or simply sliding
a needle under the skin, so that a fair amount of needle is in contact
with subcutaneous tissue.  Not enough to use 1.5 volts, but certainly
enough to use quite low voltages very reliably.  Using that route, with
a current path across the heart from two spinal needles inserted under
the skin across the chest wall outside the ribs, anaesthetized dogs can
be fibrillated with 1 second of 120 V  A.C., nearly every time (it's
now the standard method in dog cardiac arrest models, since it causes
no heart injury).  It's very difficult to do reliably by other methods
(as many live human who has gotten across 120 volts can attest).
Which, of course, is why the electric chair uses thousands of volts in
the initial charge, basically to destroy insulating skin.  Then it goes
down to 500 volts of AC or so, just so as to avoid too much cooking.

   20 microamps across fifty ohms would require 1 volt. For 150, of
course the number is 7.5 volts.  That's not much.  But it would have to
be AC and applied directly to the heart, or though subcutaneous needles
in the chest wall, with a current path through the heart.  None of this
"hold your hands in salt water" stuff.

   Loss of consciousness is apparently instant, as that much juice
through the brain causes instant seizure.  Probably the least painful
of all methods.  But you first.

   How long it takes depends entirely on whether or not the heart
fibrillates during each current cycle (couple of minutes).  It can be
less than 2 minutes.  Or it can take three or more zaps, particularly
with women, who due to more subcutaneous fat are better insulated, and
probably get less current through the heart (Ethel vs Julius
Rosenberg).  One problem is that the chair is poorly constructed, and
lacks a circuit which goes directly rhough the heart.  If this were
activated after a few seconds of current through the head, probably
most people could be killed in 10 seconds.  As it is, a few people
don't die until their brain respiratory centers have been cooked.

   Except there is some doubt that a bullet though the brainstem
extinguishes consciousness instantly.  Unless maybe it hits the locus
ceruleus or some takes out the RAS.  Sure, the person doesn't respond,
but that just means he's "locked in" (to his cortex) for the time it
takes respiratory arrest to induce ciculatory arrest.  I discount
hydraulic shock here, but there are all kinds of war casualties where
people have been shot in the head and survived, so even that isn't
perfect, unless you have a really high powered and messy rifle shot,
ala JFK.  Such a think is somewhat difficult to set up, and the family
tends to object.  Also the prisoner, oddly enough.

   I suspect an electric current extinguishes consciousness far faster
than a bullet to the head.  But the worst part of the average execution
isn't the pain, anyway, but the anticipation.  If you had to chose
between electric chair and firing squad (heart shot(s), which you're
guaranteed to feel), or perhaps gas chamber (where you are also
guaranteed to have a few momments that are no fun), which of all would
YOU take?  Uh-huh.  Thought so.  Me, too.

   Your point about deterence is noted, but applies equally well to
killing innocent people painfully, so long as most people think they're
guilty.  So deterrance by itself is not a good justification.

   The problem with executions is not just the psychological pain of
the convict, but also what it does to the humanity of most of those who
have to carry the sentence out, and those who have to watch.  It would
probably be much better for all if we limited said persons to family
members of the victim who really do honestly want revenge, and will
feel better when they have it.  Folks who really, really want the
murderer dead, and want to see it happen, and will feel better ever
after when they have.  If any such exist.  And if none do, then we
should probably not subject anybody else to this miserable experience.

   No, because resistance of tissues (saltwater soaked, remember?) will
always be less than skin.  Even wet skin.  In the electric chair they
use salt-soaked sea sponge and metal plate, and even then rely on local
burn (skin destruction under electrode) to get really good contact
(resistances of under 200 ohms, head to leg).
