This is unconfirmed news, but it seems there will be a Defkalion GT demo in Milan, Italy on July 22nd which will be live streamed on the internet and during ICCF18. Some skeptics, scientists and journalists from the international press have been invited to this demo. More details will be made available in due time.
I will try to find out more about this and update this thread if I can learn anything more.
