Yes, this is exactly the situation we’ll show in the EV test of October,
Warm Regards,
A.R.
Rossi has implied as much before, but as far as I can recall, this is the first time he has confirmed this publicly. Also, I don’t think that the October demonstration would have been announced if there was any doubt in Rossi’s mind that he could pull off a 12 hour demonstration.
