Electrostatic lifter experiment replicated.
David Sinclair
I am an electrical engineer from New Zealand,
After finding the http://jnaudin.free.fr/html/lifters.htm lifter web
site in the weekend I replicated the lifter1 experiment and got stable
tethered flight.
Details are as follows.
Construction:
Construction as per the instructions, except each side 150 mm long.
Cross bars were 2mm round spruce and all wires were 0.088 mm nichrome
as I had a spool (it's very thin and very strong). Used std kitchen
foil. Weight was 2g. Power was from an unmodified 14" colour TV.
(normally around 23Kv)
Results:
Lifted first time, hovered in stable teathered flight. My first
impression was surprise at the large amount of air being pumped by the
device. I was standing 1 meter away and could immediately feel the
draft as it hit the table and washed out sideways.
Experiment:
I conducted the following test to see if the air was responsible for
the lift. I placed a set of digital scales under the lifter covering
the whole lifter area. I teathered the lifter to the table so when
floating no part of ther lifter or teathers where touching the scale,
but all the downwash was pushing on the scale surface.
1) With power off I manually lifted the lifter off the scales and
zeroed them.
2) Placed the lifter back on the scales and read 2 grams.
3) Powered the lifter up, checked nothing was touching the scales,
reading was 2 grams.
4) Powered off the lifter, it sat on scales again, weight 2 grams.
5) Lifted the lifter off the scales by hand, weight 0 grams.
The scale readings were stable and showed no sign of interference from
the voltage.
Conclusion:
I can only conclude that all the lift is derived from downwash of air.
If the "effect" somehow produced a directional force through space
then this would not be pressing down on the scales, however it all the
force is by pushing on the air then you would expect the result
obtained. I know you have placed a plastic bag around the device and
still noticed a force. I suspect it is because the bag is becoming
charged and the effect is transfering to the outside of the bag. The
best way for you to determine this is to fly the lifter in a large
earthed metalic cage on the scales (use balsa and foil is OK). The
lifter will still fly if the cage is big enough, but no change in the
weight of the cage and lifter will be noticed as the air is
recirculated inside. (You must earth cage to stop effect just
transfering to cage)
Very interesting experiment regardless, sorry I can't give you better
news.

Naudin fails my "looks like a duck, quacks like a duck" test. See

Electrostatic energy density is quite low. Inherently so, because of its
intrinsically high source impedance.
Which is why there are very few electrostatic devices above the one watt
level.

Is there a practical application for lifting a few ounces of foil a few
inches off a table? Maybe I'm just too hard to impress in my old age.

But just imagine, Don, if it were able to generate thousands of pounds of
lift and imagine if it could do this without being plugged into a power
station and if it were controllable and compact and... Just imagine - like
we do with nuclear fusion!! <g>

NASA is reinventing a "wheel" 75 years later.

Had a long talk/dinner with a NASA engineering type.
They purposely check out woo-woo stuff and actually have a low level
"just in case" budget for it.
They put quite a bit into the Finnish weight loss program a few years
back.
