There are no data, so preliminary calculations. Let say ! The Breit–Wheeler process or Breit–Wheeler pair production is a physical process in which a positron–electron pair is created from the collision of two photons. Process 100 % efficiency laser pulse of 6,74.10^18 photons into 500 KeV (Naturally occurring electron-positron annihilation as a result of beta plus decay ) energy from two photons (3,37.10^18) counting 1,69.10^24 eV around 75 W per sample unit. Breit – Wheeler process from light electron-positron pairs, then annihilation and production of electricity preliminary assumption quasi could by up to 2000 % efficiency ( from 3W into 75 W compute of this example illustration above)

From light with the help of vacuum polarization, Breit-Wheeler process RTDG tech algorithms to get electron-positron pairs and from that electricity with an efficiency higher than 200%

Brief review of RTDG technology without technical terminology in English In movies generated using of photorealistic rendering software, animals, cars, buildings about images looks like a photos. With special mirroring of three dimensional glass models generated using of photorealistic rendering software we could see interesting shapes, text assumpions that are not visible in source three dimentional models even texture. I called this phenomenon RTDG technology. A vacuum is not an empty space, but there are various fluctuations. Goal is a portable RTDG tech chamber producing electricity with over two hundred percent efficiency and even more thanks to the additional work extracted from vacuum fluctuations. Twelve laser pulses of red, green, blue wavelengths out of four are assumed directions according to algorithms, also RTDG algorithms tech managed light storm.
