I think this gravity machine was on Vortex earlier, but in the last few
days, more photos have been published that show the final configuration,
together with the claim that it works. Clearly RARenergia think that it
does and have spent a lot of money on it.
What is an interesting question is what would it take to prove the
machine really does work. Obviously videos would not be enough.
