The E.H.D. Flying Saucer v1.0

The ElectroHydroDynamics ( E.H.D.) may open new ways in advanced propulsion. An EHD device uses a direct conversion of electrical energy into kinetic energy. A specially shaped electrostatic field creates an hydrostatic pressure (or motion) in dielectric media. If the media is a fluid like air (or aether), a flow is produced and this produces a motion of the device. A powered flow of medium (like air or aether) within a shaped electrostatic field adds energy to the system which is picked up (as potential difference) by electrodes and thus produces energy.
This has been fully used and tested by Biefeld, T.T.Brown and A.H. Bahnson in 1958. This has been fully detailled and documented in the book "L'effet Biefeld-Brown" by Alexandre Szames - (ASZ editions ISBN 2-913377-00-9 - EAN 9782913377004)
You will find below a very
simple device which shows that an EHD ship can work really. This
device is built with a thin aluminum cupola ( the shaped
electrode 250mm diameter) and positively charged at 25kV. Above
this shaped electrode there is an annular electrode ( 80mm
diameter, negatively charged or grounded ). This annular
electrode produces a non-uniform field and thus generates an
hydrostatic pressure above the arcuate electrode (the cupola).
The differential pressure in the medium between the upper surface
and the inner surface creates a mechanical force which propels
the device in one direction like the Coanda effect in a
The most interesting thing to notice is that there is a direct conversion of electrostatic energy into kinetic energy with no moving parts. The motion of the medium around the ship can be used for producing electrical energy and self-sustaining the primary effect. In vacuum space the surrounding plasma and the aether flow can be maintained in a closed path with some special shaped electrode, so it is possible to use an enhanced EHD ship as a space ship.
The picture above shows
the experimental setup :
The EHD-Flying Saucer v1.0 has been tethered with a nylon thread on a plastic arm used as a simple balance hanged on the lab ceiling. The annular electrode has been connected through a thin copper wire on the negative pole (grounded). This thin wire follows the nylon thread then was connected on a wooden pole (on the right). The inner surface of the aluminum cupola has been connected through a thin copper wire (fixed in the middle of the cuppola) to the positive pole of the High Voltage generator (+25kV). I have used the HV power supply from an old computer color monitor (IBM 8512002) (at the bottom-right of the picture).
New : The EHD-FS works also very well with my new 30kVDC-Power supply (see the diagram and pictures)
When the HV is switched on, a NET THRUST UPWARD is applied on the EHD-FS (see the video below). I have also noticed that the EHD-FS keep its final level as long as the HV is sent and very often translates to the right as shown in the video. When the HV is switched off the EHD-FS lands...
The motion of the EHD-Flying Saucer v1.0 is undeniable and fast, this proves that the effect is real and can be used for building advanced spacecrafts with this kind of technology.
The weight reduction measured was about 14% at 25kV

Notes from Jean-Louis Naudin : WARNING !! this experiment uses High Voltages (25kV), use EXTREME CAUTION, always discharge and disconnect the power supply before touch it.
