Bonjour Mr Naudin  

Je me permet de vous prendre un peu de votre temps dans le but de vous montrer mes experiences de Lifter chez moi.  

j'ai réalisé un lifter v1 qui vole tres bien et un lifter v2 qui s'envole avec tellement de force que les scotch qui retiennent le lifter ont ete arrachés ! hélas il ne reste pas droit et part violemment vers le coté opposé au fil positif.    

voici donc deux videos tres courtes (format quicktime) et une photo que j'espere voir sur votre site. Si il est possible de mettre une photo de mon lifter v2 sur votre site aussi je vous l'enverrai.      

Voila je voulais vous remercier de m'avoir donne cette passion des lifters et j'y consacre beaucoup de temps.    

au revoir
Michael

Hello!

I am Paul from Timisoara, Romania.

The Biefeld-Brown effect is really amazing.
I made yesterday this lifter in only 1/2 hour, from juice tubes, aluminum foil and copper wires. It is 20 centimeters wide.

The power supply is from an old monitor.

A+ !
Paul.

Bonjour j’ai fait ce lifter avec un ami dans le cadre d’une uv de réalisation à l’utt (université de technologie de Troyes)

Merci pour tout et merci pour ce site très intéressant !

Vous trouverez vidéos et photos ici : http://fotosupone.free.fr/photos/lifter/

Bonjour cher monsieur Naudin, nous sommes étudiants à Paris (Mérouane et Romain) et on a reproduit un lifter, le modèle de base tout simple uniquement pour l’instant.

L’originalité vient du fait qu’on a utilisé des pailles pour le construire, c’est plus léger que le balsa et le montage est bien plus simple puisqu’il suffit de les emboîter. On a utilisé du bois pour les pieds et pour fixer le fil.

Il nous a bien fallu 6 ou 7 prototypes ratés avant d’aboutir et de trouver le coup des pailles.

Ceci étant dit je tiens à vous féliciter pour votre site et pour tout le travail d’expérimentations que vous avez entrepris avec succès.

En attendant de vos nouvelles, je vous remercie et vous salue.

Mérouane.

Mr. Naudin

     First I would like to compliment you for a wonderful website.  I was able to recreate the lifter experiment only needing the resources contained within your site.

     I did not realize how difficult it would be getting a lifter to fly successfully.  I went through a few lifter design changes, but eventually got a modified version of your Lifter1 to function.  Mine is a bit smaller in dimensions, and the corona wire sits much higher due to my power source. (My power source was a 17" computer monitor.)

     I also trimmed the collector and bottom basla wood supports for less weight.  Finally though, I acheived stable flight.

     Here is a link to the video of the lifter in action.  (Would attach but cannot due to size limits.)  Also here is a link to a .jpg screen capture from the video.

Picture:  http://www.neuralimpulse.com/mikeslifter.jpg

     Please let me know if you have trouble downloading these files.  The .avi is a Divx file and requires the latest version of Divx, may not work with anything before v5.2

     This fight was completed by myself, Mike O'Konski, as well as the assistance of my sister, Laura O'Konski who helped with the project. Looks like we may be #283.  :)

     Looking forward to more successful replications, and new flights with new desgins.

Thanks again!
Mike O'Konski

PS.  I have documented my first flight on a web page. http://www.neuralimpulse.com/lifter.html

J'ai réussi à faire voler un lifter. Comme promis je vous envoie une photo. Malheureusement, mon appareil numérique n'étant pas de très bonne qualité et l'eclairage étant imparfait, ces photos ne sont pas extremement explicites. Lors d'une autre tentative, j'essaierai d'en faire des plus réussies  

Je vous remercie pour toute l'aide que vous m'avez apporté pour effectuer cette experience.  

Au revoir

Merci pour votre aide qui a été de la construction du lifter par votre précieux site à vos informations que vous nous avez envoyez par mail sur certaines questions qu'on se posait.

Notre tpe est maintenant presque fini et tout est au point. Nous avons étonné les professeurs qui pour la plupart ne connaissaient pas, juste quelques-uns qui avaient vu une fois à la télé réunionaise. Les professeurs de physique ont même été passionnés par notre projet et voulaienttous le voir voler! Je vous remercie encore une fois

Dear Mr. Naudin!

I think this Lifter Project fantastic. This is one of my first lifters, similar to Lifter1.0 but it's lighter. The first succesfull flight was on 2005.01.30.

I used 25kV.

Cher Monsieur Naudin,

Après 1 an, 2 mois, 2 semaines, 1 jour, 1 heure, 15 minutes et 27 seconde, soit exactement 38279727 secondes depuis la première fois où j'ai commencé à envisager la construction d'un prototype à Antigravité, de type Lifter, un nombre colossal d'heures de travail, pratique et théorique, d'essais infructueux, mon prototype vole !
Je vous envoie donc les photos comme Pierre-Louis vous l'avait promis. Cela fait en effet quelques semaines que nous travaillons ensemble sur ce Projet, et voir enfin ce modèle voler fut pour nous une véritable consécration ! Pour l'alimentation, nous avons construit une alimentation THT branchée sur le secteur réalisée par Flavien, le troisième homme de notre petit groupe, qui s'est averrée fonctionner à merveille pour cet usage.

Nous avons également testé un Générateur de Plasma Froid, comme vous pourrez le voir sur la photo ci-jointe... Nous comptons en effet maintenant nous atteler à la construction d'un autre prototype d'engin volant utilisant un Plasma Froid, je vous donnerai plus d'informations dès qu'il fonctionnera !

Encore Merci pour votre site toujours aussi passionant et qui nous a permis de réaliser un vieux rêve !

Cordialement,

Philippe Castera

I made it in one hour. I did not make anything with a measureing tool so I don't know the dimensions. I just did what 'felt' right  =)

I  used:

tiny straws
aluminum foil
hot glue gun with standard hot glue
some steel or silver wire from stripping stranded wire of its
insulation (I just know it isn't copper).

Power supply is a old monitor I found that had been discarded.

Flys tons better than previous ones I measured very carefully with.

Hello Jean-Louis,

I am pleased to report that I have made my first successful flight of a lifter today.

I used an old monitor as the power supply and followed the instructions provided by Timothy Ventura for the lifter.

bonjour jean;
chris gupta from south florida

This was very time consuming work, many cells very difficult job.
i left this on my work table and one day my lamp loosened fell on it and crushed it.

bonjour jean

chris gupta from south florida
to build the round lifters properly some important equiptment is necessary.
a steam machine,a hot air gun and a large diameter gasket cutting tool, and i also use aluminum tape with conductive adhesive.
my emitter is aluminum wire 32gage.i have made from 6" dia to 30"dia.

Voila donc notre deuxième hexalifter qui décolle avec une alimentation de 26kV . Nous avons pour cela, comme vous nous l'aviez conseillé, refait le lifter avec moins de plis sur l'armature en aluminium pour obtenir plus de stabilité que notre première version. Le résultat est tout à fait satisfaisant. Nous avons donc réussi deux hexalifters consécutifs, ce que nous devons à vos explications irréprochables. Nous vous remercions donc, moi et mon collègue de votre aide pour la réalisation de notre lifter.

Hexalifter de 40 cm de large
Alimentation: 26kV (écran couleur)

We've included a small video, as you can see it doesn't fly very stable. If you or anyone knows how to make it fly a bit more stable, please respond.

Bonjour nous revoilà gael et seb,

comme vous nous l'aviez demandé voici quelques photos de notre lifter...
merci d'avoir répondu à notre dernier mail et merci encore pour toutes vos explications.

Nous vous enverrons les résultats de notre tpe ,
En attendant merci et bonne route...

Cordialement , gael et seb ...

I have just to say that this is a very lightweighlifter.Made only of metal and plastic, without bars at the sides of triangle.The monitor give me a 24kv dc and the ion wind is able to extinguish a little flame.

My high regard to Townsend Brown.

I have finally completed and installed my lifter in the Gravity Discovery Centre in Australia.
Some considerations for this public display were:
  HV protection is provided by an acrylic surround (the most expensive part at over AUD$1000).
  Interactivity provided by firstly a "Soft landing" rotary control to control the pulse width modulated 24V to the HV supply. Secondly with a "Crash landing" button (red, of course) in which there is a loud spark as the 30kV supply is short-circuited and the lifter drops 18 inches suddenly. The supply doesn't like being shorted so there is a 17K dropping resistor and a 570pF 40kV doorknob that provides the energy for the spark. Kids love this button.
  Colour is provided by the argon tubes which are the HV supports and alter brightness as the current draw changes. There are three spot lights of red, green and purple to give reflections of the foil of the lifter. These were made from arrays of 8 x 5000 MCD LEDs each.
  Educational information is provided by an accompanying poster or by the tour guides.
  Reliability.  Light toy kite string was used instead of thread at a small weight penalty.  A lot of care was taken with the hot gluing (and 2 spare lifters were made). The impact point at the feet was also reinforced with hot glue. On earlier lifters I needed to put some tape on the HV feed wires to prevent them getting agitated. On this one, I left the enamel coating on the feed wires and the problem was much better so hopefully wire fatigue will be delayed.
  RF interference is a potential problem.  Particularly since there is a multidetector cosmic ray recorder on the other side of the rear brick wall.  Leaving the enamel on the feed wires seems to have reduced the RF and I also have about 10 turns of inductance on the feedwires wound around the argon tubes.
  Ozone will be produced and there is a 6 inch gap between the roof of the enclosure and the wall where this will escape. The mildly darkened theater that it is in is large with perhaps a 40 ft ceiling and is air conditioned. 
  Mains safety. I have an external switchbox which has a fuse and a microwave oven mains RF filter.

I know of only one other lifter on public display in a "Robot museum" if I recall.  I would be interested to know of any others.

Hi Jean-Louis,

Quite some time ago I emailed you about my first successful lifter here in New Zealand. Although I have not done much work with lifters since then, I have come up with what I think is a new way of building lifters. I do not know if anyone has done this before, but here is what I have done:

I created lifters with much less balsa wood than previous lifters by using the aluminium foil as the horizontal beams. Instead of covering a balsa frame with aluminium, I rolled up the aluminium into a tube about 6mm diameter. Once rolled up the aluminium becomes quite strong so it can be used as structural component. I used sticky tape to hold the foil as a tube by running the tape along the length of the tube after the tube was rolled.
The lifter in the picture was constructed from a 30cm by 5cm section of foil which was rolled up to a 6mm tube. The tube was then folded twice to form a triangle and balsa uprights were added to each corner to support the copper wire. The resulting lifter is an equilateral triangle with side length 10cm. An old computer monitor was used to power the lifter.

I am not sure how much lift was generated compared to other lifter designs, but I do think there is potential in eliminating most of the balsa wood from the lifter design since the balsa does not generate any lift. I would like to share this idea so that someone who has more time may be able to experiment with this concept.

Thanks,

Andrew Murphy

Bonjour Jean Louis,

My name is David Snyder and I live in Vanceboro North Carolina USA. After many attempts I have built my first functional lifter and I am looking forward to many more. The power supply is a GRAHV35 from amazing1.com. I do not know the weight of the lifter (have not found a scale yet) but I have calculated it to be about 10 grams, less the positive and negative leads. Attached is a MOV. More pics and info later.

Dave Snyder

I have worked on a few diff. lifters and here are some pics, they are actually about a year old, but better late than never right?

I also have a hypothesis that states that the faster the lifter moves the more efficient it will become. If you have a lifter that is having a hard time achieving lift put a fan over it blowing directly on it and it will now fly becoming more efficient. Wich would also summarize that once the lifter is in movement, the faster it goes the less power coefficient it will take to propell it! Or i also feel that by keeping power relative you could eventually reach light speed, given that the structure could withstand the forces at hand!

I would also like any info possible on building a higher (200kv-300kv) variable output supply.

THANKS & GOOD LUCK TOO ALL

Dear mr Naudin,

My name is Scott, I am an engineering Patternmaker from Melbourne Australia. Here is a picture of the tubular lifter my son and I have built. It is powered by an old monitor.  

We would like to thank you for the information on your site, and wish you the best for all your work.   

Dear Jean-Louis Naudin,

Thanks for the great docs on your web site!

We have succeeded making the lifter work.
At first there was a small problem - probably the lifter was too heavy. We cut about 1cm from the bottom of the whole construction and it started flying.

The power supply is from 14 inch display, the lifter is built according to the instructions on your site ("How to build your own lifter"), but the bottom 1cm has been cut.

We also noticed some (strange?) behaviour: we sticked extra balsa wood sticks as weights on the sides of the lifter. The strange thing was that the lifter seemed to actually lift itself more from the side with the extra balsa wood stick (although that side was heavier than the other sides).
We're not sure if this is some kind of debalancing, and also not sure that our observations are correct: more observations are needed in order to clarify.

We also noticed that if you loose the top wires they are starting to vibrate.

Your work is really great!

Best Regards,
Nikola Mihaylov, Tihomir Tihomirov - Bulgaria

Merci M Naudin

Grâce à vous j ai pu avec mon fils réussir à fabriquer et faire voler mon 2eme lifter

Ce moment inoubliable n’est ^pas près de quitter notre mémoire !!!

Notre 1er essaie a été un échec mais le résultat du second était infiniment plus satisfaisant

Et nous ne comptons pas nous arrêter là !

Merci encore

Claude et Thibaud .

Dear Mr. Naudin,  

I have successfully reproduced your hexa lifter in Czech Republic at nuclear power plant Dukovany. I take high voltage from old 15¨ monitor.
