The Marcus
Device
Marcus
Hollingshead claims to have invented a uniquely powerful
Antigravity device based on an interaction of rotating magnetic
fields. American Antigravity has interview Hollingshead
about the device and collected a wealth of information on
its construction and design.

Marcus
Hollingshead
In
November of 2002, Marcus Hollingshead began posting messages
on the BBC chat-board asking about where he could find information
about gravitational research. He indicated that he had been
independently researching gravitational effects, but he
wasn't ready to release data about his experiments at that
time.
After
some initial discussions with the BBC message-board group
members, Marcus ended up joining the Antigravity newsgroup
at Yahoo groups. This newsgroup specializes in discussing
potential antigravity and field-effect propulsion technologies,
with an in-depth focus on electromagnetic and electrogravitational
technologies.
Marcus
had initially indicated that the research underlying his
designs came initially from Earth-Sciences based study into
GeoMagnetism and Telluric
Dec
24th: "We have been working on a device for the
last 9 years that has just reached its 162nd iteration.
To date we have a 160Kg vehicle with a lift ceiling well
in excess of 700Kg at a power requirement of approx 1.2Kva's.
We have demonstrated vtol and horizontal drive."
Jan
9th: "Jan Current tests on 161 at Cambridge have
shown a lift capacity of 2040 Kilos for an overall input
power of 4.152 Kva. Or approx 5.6 Horsepower. Overall weight
inclusive of 161 was 2162 Kilos therefore overall gross
efficiency was 520 Kilo/Kva approx 470 Kilos/Hp. We hope
to have completed 162 and filed the Patent pre - end of
Jan 2003.."

Quotes
from Marcus about the Device:
Shield
Effect : "The shield effect is a slowly expanded
spherical field that is produced by an altered rp and slower
increased power and spin changes. This is complete enough
a field to form a vacuum and strong enough to be hit with
a rubber mallet and chair."
Tractor
Effect : "It's possible to produce a 'pull' field
effect as well as a 'push'. So far I've been able to focus
it for a short period of time on a 5 inch cube of wood 1.8
metres away and then drag the wood back towards the device
by 30cm or so, by decreasing the focus range but keeping
the power stable."
Temp
Effect:
"There are some things that you have to keep an eye
out for, such as icing up of the rp - but I hope to correct
that by heating the outer shell as per a suggestion by Colin."
Vacuum
Effect:
"Vacuum is a deliberate effect of a slowly increased
spherical shield, not normally present in moving variants."
(ie: having all of the coils actuated at once --Tim)
Grav
Effect: "The device acts to produce a regular gravitational
field - the field strength is increased until there is equivalence
with earths gravitational influence. Power beyond that is
'lensed' to produce movement the lensing is caused by increasing
power above G threshold in one or more of the coils (providing
they are not opposites)."
Areas
of Interest:
"1.
Lift and drive capability".
"2.
Rapid temperature reduction around the rp - -Approx 100Kelvin
when in motion".
"3.
Loss of reflected light from the rp. Increasing amounts
of power (in balance - ie no movement) leads to a gradual
darkening around the rp - eventually to the point where
the rp is no longer distinguishable".
"4.
Inertialess movement - instant change of direction for the
device and anything contained directly in the field - not
true for carried objects that are too large to be so contained".
"5.
Fixed device (prevented from moving) is capable of exerting
a force on unattached objects - pushing them away".
"6.
Field is capable of being broadened and weakened or narrowed
and amplified - termed gravitational lensing".
"7.
The field is capable of producing an air tight 2.2m diameter
spherical vacuum."
