After reading DePalma's review on this book it reminded so much about
typical armchair critics (one who has lots to say but little or no interest
in actually doing the experiment) I thought I should check out at the
library instead of wasting money on it.
See the following link for DePalma's view on this book at:

Many thx for all the info you sent Bill. I found this very informative. The
Japanese links were very interesting one of your links needs to be updated
from:
http://www.depalma.org.nz/ to http://depalma.pair.com/
I am still going through all the info in the links at the moment.

With such low voltages I think there is no option but to use liquid contacts.
Where can I get indium-bases solder I have never heard of it? This is
fantastic its about half the temp of boiling water. Hope you don't mean C
instead of F?
Although in a totally sealed environment Mercury may still be an option.

Think its really worth looking again at DePalma's patent application at:

DESCRIPTION OF INVENTION
According to the present invention there is provided a single piece
homopolar generator which has one moving
part, the rotor and in which the desired electrical potential is produced
without the mutual interaction of a second member (stator). This generator
includes an electrically
conductive member such as a cylindrical tube having two magnets therein
which) when the generator is in
operation, rotate with the tube. The cylindrical version of this generator,
known as a QUADRAPOLE, is not an
immediately apparent development of the original Faraday 'one-piece'
axially rotated magnet experiment since
the vector directions of the (radial) magnetic flux lines and axially
flowing electrical current are interchanged in their respective directions
in comparison to the previously described Faraday Disc experiment.
[snip]
Besides the above configuration he discusses a number of other variations
and limitations eg:
Without the provision of external pole pieces and a closed magnetic flux
path, the attainable magnetic
field strength within such a machine would be so low as to render the
machine not suitable for commercial
application. Rare earth high strength permanent magnets make it possible to
obtain high strength and useful
radially directed magnetic flux lines without closed magnetic flux paths.
The radially directed flux arises
from mutual repulsion of homopolar flux fields. [snip]

>If the N-machine's massive output circuit is built from radially

Here is another quote from the said patent that somewhat address the above:
Due to the high currents generated by the generator, super conducting
materials are particularly suitable to be incorporated in or used with
cylindrical tube.
A generator of the type herein before described can produce very high
output currents (multiples of kilo amperes) at low voltages. The withdrawal
of high electrical currents from the generator results in a magnetic field
consisting of circular flux tines enclosing the central zone of the
cylindrical tube. A method of cancelling or at least minimizing these
effects will now be described with reference to figure 7 of the drawings.
Referring to figure 7 there is shown a schematic representation of a
generator similar to that depicted in
figure 1 including magnetic compensation means. In the embodiment shown a
conductive compensation tube is positioned about and spaced apart from, the
central zone of cylindrical tube. One end of compensation tube is
electrically connected to contact by conductor . The opposite end of
compensation tube is connected to outward terminal of the generator by
conductive connection. Compensation tube remains stationary while
cylindrical body rotates relative thereto. Compensation tube produces
compensatory circular magnetic flux which cancels the field generated by
withdrawal of current. This works in the same manner as a coaxial cable;
whereby equal currents flow in opposite directions thus the magnetic fields
thereby produced cancel each other. The cancellation of the magnetic fields
due to the high currents in the generator is important, since the field
distortion (armature reaction) produced by these currents when
uncompensated can limit the power output of the machine by altering the
perpendicularity of the flux lines to the rotating cylindrical tube.
According to the RealAudio Link to "Sightings" Broadcast of 28 August 1997,
BP says that about 2 hrs in the interview says that N-Machine is being used
in the US navy subs? Anyone able to confirm this?

BTW what happened to DePalma? Is he still around thought he passed away if
so how?
Thanks
