Free energy researcher Ruslan Kulabuhov aka TOP RUSLAN sold his BTG generator to some secret persons in U.S.A. This is smallest version of all of his overunity generators and have 40 Wt output power. Leaked video is from states. Very probably intentionally leaked to public.
This BTG is Ruslan copy of Edward Lee Dally BTG with 450 wt output where he used nanosec generator instead Tesla or Katcher
and this one is 2kwt with electronic controlled Tesla transformer.
Last 2 BTG still have not sold.
P.S. Kulabuhov last year also sold his 3 kwt BTG to some unknown Russian guy Sergey and bought yourself new BMW cabrio.
