How to build your own AntiGravity floater - With videos

That's cool stuff. My younger brother made a lifter for his science fair project a couple years ago and used an opened computer monitor to power it. These lifters operate at < 30 kiloVolts.

If you build or buy a power supply > 100 kV then you can tap into the biefeld-brown effect and get real antigravity. There's debate about whether lifters really employ antigravity or something closer to ion wind or nitrogen ion drift. I wrote a commentary on this here.

The biefeld-brown effect shows that high voltage capacitors, paralle plate or asymmetric, acclerate towards the positive pole when charged between 100kV and 250kV. Lifters, on the other hand, move towards the thin wire electrode regardless whether it is positive or negative, therefore it is more likely some ion drift phenomenon than the biefeld-brown effect due to it not depending on polarity. The biefeld-brown effect should be present in a small amount, but at 30kV it would be miniscule.

One example demonstrating something close to the real deal:

Hi Whywhywhy,

(glad to see you back) -  From what I understand, the lifters have a thin wire running around the top, and a flat aluminum foil fin tracing the same path an inch or so below. The top wire is charged positive or negative, and the bottom is grounded or given the opposite charge.  So a cross section looks like this:

a
i               *   wire cross section  (+)
r
                ||    foil cross section    (-)
|               |
|               |
|               |
V              |   
                |
                |
                ||

Basically, air gets charged up at the wire and attracted downwards to the foil, then upon reaching the foil gets neutralized and then (if the foil is charged and not just grounded) gets repelled again. The entire process flows from top to bottom, therefore the lifters rise in the direction of the wire. By the time the air gets neutralized and recharged oppositely by the foil, it's already moving downwards...so the extra repelling push it receives (in addition to the attractive pull right after it leaves the area of the wire) is also directed downwards somewhat.

A lifter placed on its side will move sideways. Or if held still, it popels air.  I tried this with my brother's lifter... you can definitely feel cool air blowing away from the bottom. Hmm, I wonder if it would make a nice solid state cooling device...

You can buy a pre-built power supply here:

Or go cheap and get an old working computer monitor, open it up, and connect that suction cup thingy that goes into the CRT to the wire of the lifter, and the foil to the computer metal chassis. Don't fry yourself if you do this, look up info on the web for directions and safety tips if necessary. I let my brother plug the monitor into my variac to vary the voltage, but otherwise just turning the monitor on made the lifter fly. It had to be tethered down by strings taped to the table. Was pretty cool...

I'm planning on building a 100kV supply eventually, maybe higher, to do some real antigravity stuff. In high school I borrowed the Van de Graaf generator to do some biefeld-brown experiments, but discovered its current output wasn't high enough to overcome leakage in the capacitor. I made the capacitor from stacks of photo lamination sheets interleaved with aluminum foil. It was suspended perpendicular to the floor and expected to swing a little towards the positive pole, but movement was very slight due to charge not building up enough.

There are other ways to make it work better... a parallel plate capacitor is symmetric all the way through. If instead an asymmetric capacitor is used, like at that link I posted (bmiklos2000) then even at 100kV it works... the asymmetry boosts the effect due to nonlinearity in the electric field. The Lifter also is an asymmetric capacitor, with a wire at the top and foil fin at the bottom, except I think the asymmetry helps with the ion drift there as well.

I bet that if a lifter is placed in a good vacuum and given a 100kV or greater potential, it would move solely due to antigravity effects.  That means a craft like this would work both in the atmosphere and outer space. That's awesome.
