The Italian CF guys say they are shipping out commercial units in three months. This will be the test.
Will they ship them by deadline?
Will they work as advertised?
Then you will know if this is for real
Disagree with the shipdate. Bad things happen, if the ship date slips - that has no bearing on the practicality or functionality of the device. What matters is does it work as advertized - and is it repeatable. If you built 128 units, and they all work - then I'd say "Yup, it's repeatable".
That's what killed the Cold Fusion from ~10 yrs ago. There were viable theories of what happened - obviously something happened. But, it was not repeatable. Not a scam - just a fluke that was never really understood. It happened only 2-4x out of hundreds of attempts to replicate it.
This system is turned on by a light-switch. It has 'allegedly' been started and stopped thousands of times without incident. You have to be pretty sure to call an international press conference, and flip a switch in front of everyone.
