This is a philosophical approach and is based on the idea that all
parties are interested in TRUTH above all.

That all parties are honest at all times
and that there is no hidden agenda.
and tat science presides over superstition.

In the 1950's there was a push on airframe technology and it came to
be realized that the 'lifting body' concept, the idea that the
fuselage itself contributed to lift, was a better idea than the hot-
dog with wings air frames.

A Pentagon report classified anything remotely like a lifting body is
inherently dangerous and it took over 30 years for actual engineering
AND lots and lots of proven results before the military would even
consider such an airframe. Now, it is hard to find a military jet
WITHOUT lifting body technology.

The possibility, however remote that both Tesla and Einstein were
completely wrong in this one area is probably more silly than the
idea of a ship that can be hidden from radar.

After the fall of the USSR, the US was able to take possession of a
ship that had been crisscrossed with massive coils. Depending on the
orientation of the ship to the earth's core, and the charge in the
coils, the ship was able to have a zero net effect on the magnetic
fields around the ship. This would offer a zero profile to detecting
the magnetic mass of the ship.


The idea that one can take a 'thing' and make it out of phase with
it's environment and render it invisible in the visible light
spectrum is no more ridiculous than one being able to make it
invisible on the infrared or even on radar or magnetism.

The technology may not exist, but how certain can one be that it will
never exist ? or that some group did not cross that threshold at one
time ?

I'm not saying it did or did not happen. But I am saying that the
possibility of it EVER happening, either in the past or the future
would tend to lead to the possibility of such an occurrence.

Review the laughable idea that the Earth was round, or that the sun
did not revolve around the earth, or that the Earth is the only
planet in all the Galaxies.

I don't mind hearing people's opnions when stated as such, but to
have no persoanl research and formal experiance in an area and then
proclaiming something as either impossible or rediculous is a
disservice to those who have the power of creative thought and
scientific imagination.

In other words, those that believe something cannot be done should
get out of the way of those doing them.

Personally, I loathe the current superstitions that claim to be based
in sciences.

I am working on a high-gain current-to-voltage amplifier. I need to
convert a very low pulsed current signal (100 microsec, <nanoamp)
into a voltage signal (>10 mV) that I can read from the scope. I
tried the amplifier using a low-gain (0.2 V/microamp) setting, and it
works ok. When I tried it with a higher gain (2 V/microamp),
oscillations (~10 microsec, regular amplitude) showed up on the scope
display. I'd like to fix that, but don't know how. I need some help,
if you know how to fix it and what is the cause of that, please let
me know. Thanks!

I would say if there was something done it is gone wrong i expect.
You can't make money with something not working (and possibly being dangerous).
They wouldn't tell us i reckon.

I really see not much positive use for this technology, we shouldn't need
to hide things, should we?

As others have said, you probably mean the so-called Philadelphia
Experiment. It really was just a secret wartime project to try and
counter enemy radar. What better way to hide the project from the
enemy than to add ridiculous details?

I have some genuine Penn and Teller Magic Healing Crystals if you

I think you are talking about the Philadelphia Experiment.

The story goes that Nicolas Tesla and Albert Einstein had worked
together to help 'cloak' a ship. The test subject was the USS
Eldridge, a destroyer escort of the Cannon Class, was to be tested to
see if they could make it so radar would not detect it. The test
based in the Philadelphia Naval Yard, but was conducted out at sea.

With the world in war, there were projects that were revolutionary,
the Manhattan Project was to create a Nuk-u-ler bomb.

The stories around the Philadelphia Experiment include things like
the test was successful in making the ship invisible to radar, but
also invisible to observers, thus proving Einsteins theories about
space and time. The supposed magnetic field curved space and time to
such a degree that some really odd things were added to the stories.

One is that the metal of the ship altered structure and became
transparent, not only to remote observers, but also the people on the
ship.

Another is that in the bending of space and time, another ship, a
flying saucer if you will, was seen by the people on the Eldridge.
Oddly a town was also seen by the people. Some people guess that
this odd occurrence may be due to a similar experiment in a town and
also on one a space ship. It is guessed that if all three were doing
a similar experiment that somehow they may have been connected by the
gravity and frequency of the generated fields.

Whatever really happened is something few will ever know. Due to
military secrecy at the time, there was little reported outside of
the normal channels and that only helps the stories.

And IF they really did create such a device, the thing was not
controlled and not useable and would have been filed away as top
secret.

But, if you find out more than the average websites, and by that, I
mean real hard data on how to make the stuff, let us know.

Mike, what I was saying (not very well) is that the English system is a
better way to go. It's not possible to stop people doing their own work,
no matter how much legislation or licensing is specified, so another way
needs to be found.
To me the obvious way is to let people do their own work, owner-builder
if you like, but insist they have it inspected cheaply before its
passed.

This will save lives, including those of future electricians who may
have to work on it later.

It wont make less work for any licensed electricians, as these
owner-builder types will do their own anyway, so lets encourage them to
get it inspected so no-one gets hurt.

Of course, sorry i was unclear.
Your drawing is a 100% correct, what i showed is the first sine approximation.
According to Furier Analysis you can composite any periodic signal from a number
of sine signals (generally indefinitely many). the first sine signal (having
the fundamental frequency of the signal itself) has normally the highest amplitude.

I showed that the 1st sine approximation, which is a indicator fot the "bulk" of the
signal, has phase offset.

I still do not believe there is reactive power.
(I think the therm "reactive" demands that there is energy delivered back to the source
at some point)

But we were told if there is phase offset there is reactive power so you see i don't understand.
This is bothering em some 4 years now.

I toyed with a design not too long ago that would have generated a
logarithmic sweep voltage and swept the MAX038 while applying horizontal
drive to an oscilloscope, and thereby produce 2-D frequency response graphs.
I don't know if that is practical or not, but it sounded cool.

i do not think you can actually get usable numbers out of it.

i only did it once in a school lab this way, was a nice summer day and
we wanted to go home early. amazing what you can do with a digital scope...
well, we did go home early after all...
But i used a professional generator then, no max038.
