How do we know this for certain? We have the USA border security, Homeland Security and NSA to thank for that - because the stone that was neatly tucked away in my bag on the plane, crashed the NSA security scanning system as we were leaving for the USA. The energy fields get generated by inputting sound frequency into the hole at the centre of the stone which results in large energy fields being emitted by the stone.
I look forward to feedback from Nassim and his team regarding any findings in this area. I personally believe that we can replicate these stones and create infinite amount of free-energy from simple technology we learnt from ancient civilisations.
