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% Preliminary quasi-calculations 100% efficient laser pulses RTDG tech algorithm by 6.74.10^18 photons conv
