Bonjour,
Nous vous avions déjà contacté l'année dernière lorsque nous
avions réussi à faire voler nos premiers lifters. Nous sommes
deux étudiants en Physique-Chimie à Bordeaux et le lifter est
un sujet d'étude passionnant. Nous essayons actuellement de
réaliser des mesures de tensions, intensité et de forces. Nous
serions d'ailleurs intéressé de discuter avec vous des
recherches que vous avez déjà menées. Voici quelques photos
datant de nos premiers essais.

Dear Jean Louis,
Thank you for your help on my lifter project and thank you for a
very helpful,interesting website. After 2 weeks of experimenting
I have finally achieved lift-off. :-) It took a total of 4
lifters and 8 computer monitors. I have since learned the newer
monitors (95 to present) will not furnish the power I need
unless plugged into a computer. The lifter is not as stable as I
would like it to be but it does fly. This has been a wonderful
project for my daughter and I. We will continue to overcome all
obstacles and improve our lifters.I have enclosed a picture of
our best one.
You have done a lot of research in this area ,
Please keep up the good work!
Thanks Again!!

Hi Jean Louis,
Thank you for your help on my science fair project. I found that I needed to make lighter lifters to get them to work. The most successful one weighted 2.46 grams and was about 11.5cm long on each cell of the triangle. I found that the best tether height was between 4 and 5 inches (10 to 12cm), otherwise it got all wacky. At that height it was able to lift a payload of .24 grams (a small piece of origami). I would like to be registered on you lifter experimenters page. I have copied some pictures below and also have attached them.
Thank you, Chris Capasso

Dear Jean-Louis,
I just had to take a
break from my H2O cracking experiments to try a
"lifter". As part of my expertise is Electronics, I
thought, "this will only take an hour or two",,,
well, several hours later, with an old "parted"
monitor board, (crt HV ckt), and, a modified design, I got
one to fly. It was quite exiting ! . I did receive a few HV
shocks, but not being grounded, they didn't really hurt me.(we
live in a "strawbale"house with wooden floors). The
original design was too heavy, (I wonder if the aluminum foil
we get here might be heavier) , so I built one with less Balsa,
(The minimum to hold the shape). As you can see in the pics,
the wire levers against the support balsa spokes to
keep the foil tight. The fold on top of the foil, I also
eliminated, for weight reduction.
I tried to anchor the corners with fishing line, but it
wanted to fly all over the place, (this is when I received the
shocks !) , So, I drilled a small hole in the center of the
spokes, and ran a small thread to the ceiling, with a small
weight on the bottom. Now, When I apply power it simply rises to
the top, with the thread as a climbing guide. I have not made
the pwr supply "variable" yet, so I put a small thread
from the center with a few small elastic bands to the ceiling, to
prevent the spokes from breaking when I shut the power off. It
has impressed and bewildered many people.
Following this (as another expertise I have is
Aeronautical Engineering), I wondered how to adapt this principle
to "rotation" , so I took a flat piece of balsa,
16"x 2" and ran a wire down the leading edge of each
side of the "propeller", and a small strip of foil down
the trailing edge, The two wires I put under a small washer that
that held the propeller to a small 1/8" brass rod, the rod
was connected to one of the HV wires. The foil on the propeller
is not connected to anything. Further, I put a "printing
sheet" (.008") aluminum foil under the propeller and
around the brass support rod.
I was working on the capacative
inductance theory, thinking the foils on the propeller would
induct voltage from the aluminum printing sheet beneath.The
propeller rotates at about 250 R.P.M., with a spacing, (between
the propeller and ground sheet of 3 "), . The closer the
spacing, the higher the rpm. Assuming the force would apply
from the wire in the direction of the foil, it should turn
counterclockwise, However, to my surprise, it did the opposite
! . The propeller turned backwards, and when I reversed the
polarity, it did not reverse the direction of rotation !!.It
still turns clockwise, looking down from the top. I have not had
time to analys it yet.
It is however a very easy and inexpensive experiment that
someone may be able to improve upon.
Here are the pics, (re: mail of 02/06/04)
I sent the propeller ones too.

Greetings Jean-Louis:
Finally got around to putting some stuff together to mail. I have
been playing around with lifters since about MAY of 2003 ever
since running across your webpage. Thank you so much for your
commitment to this great source of scientific discovery and
sharing. I hope you will be able to share all the enclosed with
the lifter community.

Hope some find this stuff helpful and
inspiring. Thanks to all those with the innovative designs (I
enjoy studying each one) and to Jean-Louis for making this all
possible.

Bonjour Mr Naudin.
Je vous ai envoyé le message suivant il y a quelques semaines.En
voici une copie, accompagnée de modestes photos que j'ai prises,
en attendant mieux. Actuellement, je me suis lancé dans la
confection d'un second lifter, dirigeable latéralement, afin de
vérifier que des applications à la construction d'aéronefs
sont envisageables.
Etudiant en classe de mathématiques spéciales à Chambéry,
j'ai choisi de travailler sur le Lifter dans le cadre du TIPE
(travail de recherche à mener en équipe pour l'oral des
concours).
Avec mes camarades, après d'infructueuses tentatives de
fabrication d'une alim THT, nous nous sommes rabattus sur la
solution de l'alimentation via un moniteur d'ordinateur, et c'est
ainsi qu'aujourd'hui, 19 décembre 2003, un basic lifter a
décollé dans les laboratoires du Lycée Vaugelas.
Nous allons donc continuer à travailler sur le sujet, et vous
feront part de nos éventuelles avancées.
Merci de votre attention et bravo pour la masse d'informations
que vous publiez sur votre site web.

hey! ici deux jeunes du Québec(st-basile le grand), Jonathan Goyette et Nicolas Lupien, qui aimerais vous faire part de leur toute dernière réussite, nous venons tout juste de reussir a faire volé notre lifter apres 3 jours de travail intensif. Notre vol na pas été entièrement stable car nous avons rencontré plusieur problème. Nous avons tout D'abord eu un probleme avec notre fils de cuivre qui etait pas assé resistant , nous avons mit un fils 1/10 mm cela a tout reglé. Notre premier lifter etait en goujon.. il ne volait pas.. le balsa a tout reglé!
merci a vous de nous avoir aidé a reussir!..dsl de la tres mauvaise qualité d'image!..

Hello Jean-Louis
My name is David Gealt, I'm 24 from Queensbury, New York, USA. I
have just completed my first successful test flight of the
lifter.
This was my fifth attempt at the recreation of an electrokinetic
lifter.
The first 2 were made out of a heavier wood than balsa and did
not achieve lift.
The third and fourth used styrofoam instead of wood but I believe
I used too much. I had a little bit of excitement with the third
in that the superglue I used reacted with the styrofoam, creating
what I think was similar to a home made napalm base. The positive
electrode wire was coiled around the styrofoam with this material
between it, when it was powered it caught fire. It was not
dangerous, it was a small fire, about the size of a candle
flame... but it was very entertaining. :)
But try number five... I found some balsa wood, and it all worked
just fine. It flew on the first try.
It is powered by an very old AT&T color terminal monitor
(model: CRT 318/T) that was donated by Vincent Spero who's son
Sean (a good friend of mine) has helped me with my experiments.
Most of the tests have been recorded using a high-quality digital
video camera, and the clips will soon be available from my
personal website
http://jove.prohosting.com/narcos/
I definitely plan on expanding my experiments, and have a number
of good ideas I can't wait to try out.
I am also studying the Searl Effect and the Law of Squares,
however this seemed like a more easily achieved experiment, less
expensive as well.

Dear Jean-Louis,
My dad helped me to build and test a lifter for my science fair project. We tested the lifter with a piece of cardboard on a stick inserted between the top wire and the aluminum foil. The lifter flew great. I am sending 3 photos showing the tests we did. I am in 6th grade and my name is Sophia Rex. I live in Brigham City, Utah USA and am 11 years old.
Sincerely,
Sophia Rex

Jean Louis Naudin,
C'est avec plaisir que j'ecris ces quelques mots : Merci beaucoup pour m'avoir permis de faire voler mon second lifter. En effet, mon premier lifter à brulé à cause d'une grosse etincelle, mais le second est un succés. C'est un lifter de modèle 1, dont les branches verticales sont un peu plus grande. Le vol est assez instable, mais en raccourcissant les fils de nylon, ça devrait aller mieux. Ci joint une petite video du vol, certes très peu stationnaire, de mon lifter, et une photo. Encore merci, et à bientôt pour un autre vol.
Alexandre Franguiadakis.

Nous vous avions déja contacté, au début de
l'année scolaire (Benjamin Le Guenic et Tristan Massot), dans le
cadre de nos TPE, pour vous demander quelques renseignements qui
se sont avérés très utiles, ainsi que des adresses.
Nous avons donc tenté notre premier vole de lifter v1.0 avec
succès le 28 novembre 2003. A chaque fois que nous l'alimentons,
nous gardons toujours le même étonnement. Effet garantis
auprès de nos professeurs et camarades ! Nous sommes très
content de faire partie des personnes qui ont fabriqué un
lifter, même si notre expèrience reste très modeste.
voici les caractéristiques de notre lifter :
Triangle de 20 cm de coté (celui de votre site)
Masse à vide : 1,9 grammes
Masse total en charge maximum : 3,4 grammes
alimentation : moniteur couleur 30 kV
Nous vous remercions encore une fois pour votre site si complet.
Nos expériences ne vont pas s'arrêter en si bon chemin, et nous
vous tiendrons informé de notre prochaine fabrication.

Bonjour Jean Louis
Apès etre tombé par hazard sur votre site je me suis lancé dans la construction d'un lifter basic. Je l'ais terminé cette après midi et apres quelques petits réglages il vole. Son vol est pas très stable il est plutot nerveu. J'utilise comme alimentation un vieil écran d'ordinateur (d'un ancien comodor) qui me délivre du 25kV. Je vais bientot me lancer dans le montage d'un lifter v2.0 et surement par apres d'un Hexa lifter. La qualité de la photo n'est pas une des meilleures mais d'autres vont suivres surement.

Dear Mr. Naudin
Our hexalifter reached the biggest distance from the base on 30
November 2003 in Pilsen, Czech republic. It was 116 cm.See the
other photos on my web www.mici.cz. Greetings for you and your
friend. In the New Year 2004 higher, better and cheerfully with
the hexalifter!

Hi,
I finally achieved a successful flight of a lifter. I used a 35KV
power supply with a 1.5mA rating. The lifter flew at 28-30KV. I
used 50 gauge corona wire for the positive pole. It took me three
weeks to achieve a good design. I had to experiment with the size
of the foil and purchase corona wire. I have included a photo of
the flight. Pardon my messy garage!
