    E = 0.5 C V^2.
    E = 100 kJ
    C = 75 mF
    V = 45 kV
    These numbers on the LPPFusion slide @10:38 do not compute.


    Good catch–it is two typos–The font is wrong on the capacitance–should be symbol “mu” for micro farad, not “m” for millifarad. Also, the capacitance is for 8-capacitor configuration, while the energy is for 12-capacitor. For 12 capacitors, the correct C is 113 microfarads–then the formula looks right. (We rounded 114 kJ to 100 kJ)

    Funny you were the first to notice it 9 months later. It is in the video, so I guess the only way to correct it is in the caption for the video.


    Being an Oxford alumnus myself, I felt it was my duty 🙂
