Free energy ? Is it possible ?

   Surfing on the web, I came across some informations, published by a serbian academician called Veljko Milkovic.
   His invention is a two stage mechanical oscillator, which he claims to produce more power that is required to keep it functioning. Perpetuum mobile ... overunit device ? hart to tell.
   The inventor released a series of films on youtube, that must clarify that his devices really produce more that they consume.

 

   For those interested here is the inventors website.
