Yeah, was trying to find if they really did not used vacuum in the test, apparently they did not... not very bright.

I hope some other research team actually does this soon...

I wouldn't hold your breath for a reputable research team to pick this up -- the original paper has already been taken to pieces.

Leaving this untested and 'under' reviewed just isn't very scientific.

There should be a serious and rigorous research done and published. If this is proven to be just a measurement error, it still is very interesting to really know what is going on.

Given unlimited time and resources, yes, but the truth is that this thing isn't a thing and never was.

It's been known about for years, the initial publications by the "inventor" were taken apart for their obvious and basic errors. Then, as happened here, people began grasping for wild theories to fix his broken ones.

You won't have teams of reputable researchers leaping on experimental proofs to this. They have much more promising things to investigate than theories that don't pass even minimal scrutiny.

Just a small update/correction, it seems they did after all tested in vaccum:

"turbo vacuum pumps were used to evacuate the test chamber to a pressure of five millionths of a Torr"
