  Dr Rossi,
  At the global presentation of the Ecat, will you make public also the certification of efficiency made by a third independent party ?

  I am not an expert of Heat Pumps and I am not able to answer: I think that the last comment of Paul Dodgshun of 2026/10/29 is intelligent,

  Dear Andrea Rossi,

  For the NGU non-SSM 100W units:
  1. Must the input power be tied to a ground: Grid, others?
  2. Will the unit function correctly with Grid 120VAC applied power?
  3. Will the unit function correctly with Grid 240VAC applied power?
  4. Will the unit function correctly with 12VDC applied power?
