I merely raise the correct questions.

=20

As I said, I've had trouble with this demo and the Faculty I work with
don't understand it.

=20

That is all I mean to say.

=20

I certainly don't think Dick's demo is bogus. No.

=20

But therefore, I do sing you a song...

=20

=20

Whenever life get you down, Mrs. Brown,

And things seem hard or tough.

And people are stupid, obnoxious or daft,

And you feel that you've had quite enu-hu-hu-huuuuff!

=20

Just - re-member that you're standing on a planet that's evolving

and revolving at 900 miles an hour,

It's orbiting at 19 miles a second, so it's reckoned,

the sun that is the source of all our power.

The Sun and you and me, and all the stars that we can see,

are moving at a million miles a day,

In the outer spiral arm, at 40,000 miles an hour,

of the Galaxy we call the Milky Way.

=20

Our Galaxy itself contains 100 billion stars,

it's 100,000 light-years side-to-side,

It bulges in the middle, 16,000 light-years thick,

but out by us it's just 3000 light-years wide.

We're 30,000 light-years from galactic central point,

we go round every 200 million years,

=20

And our galaxy is only one of millions of billions

in this amazing and expanding universe.

The universe itself keeps on expanding and expanding,

in all of the directions it can whizz,

As fast as it can go, at the speed of light you know,

twelve million miles a minute, and that's the fastest speed there is.

=20

So remember, when you're feeling very small and insecure,

how amazingly unlikely is your birth,

And pray that there's intelligent life somewhere up in space,

because there's bugger all down here on Earth.

=20

That's all,

=20

so you are saying that Dick's straightforward with clear results is
bogus??

=20

Why would a toroidal iron core be needed?

=20

If Dick's demo had faraday shielding around the plates - would it still
show results? - would it be more satisfactory to the ney-sayers?

=20

More discussion on this would be appreciated (i.e. I'm too lazy to do
the research)

I've never had luck with this demo for two reasons. It is tricky to do
correctly. And when I do get it working the Faculty are not
theoretically convinced that the signal is any different from an RF
antenna signal.

=20

1.) To do it the pick-up coil must be a many turns iron core Toriod.

=20

2.) The AC signal on the cap plates should be of high frequency. One
handy, free way to get a very high frequency signal is to get an old VCR
player, play a video tape and take the RF signal output out the back.
RF modulators with a 4 MHz bandwidth are commonly found built into old
VCRs
