The Antigravity Underground

The fantastic floating device called a lifter has no moving parts, no onboard fuel, and no shortage of wide-eyed admirers. Even inside NASA.

It's time for liftoff, so I pull on my thick, elbow-length rubber gloves and put the fire extinguisher within reach.

Well, the acid test would be to stick the thing into a vacuum chamber and see if the performance is substantially the same.

Vacuum chamber?

Did you say "vacuum chamber?"

From the article:

.... He created two capacitors that are tubular, like tiny jet engines - with the hot wire on one end, a gap, and a metal tube for the ground. Each capacitor is mounted on the end of a rotor, driving it like a pinwheel. Last fall, they tested the contraption in regular air - shooting it with 27,000 volts at 20 microamps. Bingo: It generated 3 millipounds of force, and the rotors spun at 60 rpm.

Then, in December, they finished tweaking their vacuum. They were able to get the pressure inside the bell jar down to the equivalent of low-Earth orbit - 10-7 torrs, to be precise. They put the device inside and hit the juice.

Nothing happened.

It wouldn't budge an inch. They jammed the voltage up to 50,000 volts, and still nothing. They repeated the tests several times but didn't dare use higher voltage. "We had lightning coming out the back of it," says Andy Finchum, Campbell's assistant, pointing to a set of plastic guards he set up after nearly frying himself. "You could start hearing the hiss at those voltages, and that's when you don't want to get close!" He hands me a thick gray pressure gauge. "These are $1,500 apiece, and we toasted one."

To check if it was an equipment error, they brought the bell jar back to sea-level pressure - and the rotor started spinning again. The device itself wasn't malfunctioning.

Campbell folds his arms and declares antigravity dead.

"There's no performance in a vacuum," he concludes. [snip]

OK.

He's got a point. If it only happens in atmosphere...then it's some sort of atmospheric phenomenon, and not antigravity per se.

I need a circuit diagram before I can evaluate or make a comment.

I do one last check of my DC transformer, which I bought online from a guy who specializes in energy systems that are illegal in several states. He put a sticker on this one: DANGER: ANTIGRAVITY IN DRIVER.

A power suppy from an old computer moniter works just as well. I built a lifter last year and it really does work.

I remember reading about this back in the 1960's in either POPULAR MECHANICS or POPULAR SCIENCE. The cover of the magazine showed an anti-gravity "flying machine" monitoring road trafic.

This is not new. Check out this link from 1964

The 1964 explanation sounds correct. What essentially exists is a particle accelerator that produces secondary movement of neutral particles.

It is ionic wind. Once you approach a voltage gradient of about 20,000 volts per inch, air molecules start ionizing. You can put "pin points" on one side of a charged grid. The charged grid has a slightly lower gradient, so it doesn't ionize air molecules. The pin points do ionize the air around them. Once ionized, they are either repelled or attracted to the grid depending upon the charge. This creates a wind, or in rocket terms, a reaction mass. It is just like rocket exhaust. It heads one way and the "craft" moves the other way.

Trouble is, once you get the generator of the 20,000 volts onboard the craft, it won't be able to overcome the weight of the mechanism.

'Lifters' won't be going anywhere, unless they can go beyond the length of umbilical wiring they presently use.

It's nice to see that science and experimentation is still practiced so jubilanyly at the amateur level. And conversely, sad to see NASA acting like the old, wheezy protectorate that we read so much about- in investigations of tragedies.

acid test

Huh? How about not scraping the remains off one of the walls that still moves with earth's rotation?

There are some great instructions on how to build lifters at the site below. I built one last year using an unused CRT as a power source and maybe 5 bucks worth of parts. Lifters are also awesome science fair projects.

Good article, and they were honest about the ion-wind effect too.

Did you have a room to do it in? I would like to make a lifter but I don't have a spare room to use. Suppose I could do it in the yard. Then again I'm a little leary of 20kV.
