Thanks to Bob Greenyer for posting the following comment and video showing the lab of Anatoly Klimov in Moscow, Russia.
Anatoly Klimov’s device which uses Tesla coil and said to reach COP10 is looking more stable in recent tests.
This is one of the labs I am invited to visit, and Klimov has said we can conduct any test we like.
He says that he only sees SR [strange radiation] in the exhaust gap and only then over short range. This is to be expected as the device is a continuous flow type and so less time to build quanta.
