Lifter device testing in a vacuum

I believe TEN had mentioned that these things wouldn't work in a vacuum due to ionized air flow. Well here's a lab who did sucessful testing in a vacuum. I'm sure there's a reason this cannot be harnessed, but maybe someone would fill in the blanks for me? Is it a matter of directionality or something else I'm not thinking of?

Here's the paper that was published on it- it's in PDF format.

No comments so far? I would recommend reading the paper on this subject, so it becomes clearer

Zantra: I would recommend you read it (the 2nd site you referenced). Then tell me why you think it has anything to do with the first one about dielectric thrusters (lifters).[?]

It doesn't? OK my mistake. It was the paper referenced by the same site. Unfortunately I had some difficulty understanding the paper to the fullest extent.

Someone clear this up for me?

Do you know the LEVITRON ?

Maybe the LIFTERs works on a similar principle, but electrostatic, and needing no spin to maintain the equilibrium of forces.

I've cross referenced this, and as far as I can tell, it's a haox. Only two experiments of this type were properly documented, of which one was peer-reviewed. Both were negative. The latests one even detected a relationship between the pressure of the gas around the lifter drive and it's thrust, suggesting strongly it was an ion wind effect. The other experiments that do confirm it could not be reproduced, and hence were probably due to the use of an inadequate vacuum.
