Tensor, for your response (and I thank you for being candid in your opinion), you should be aware that Bryan Belrad is entirely self-taught in matters of advanced physics. One of the reasons he's always eager to answer questions, at least in my experience, is that he learns from his mistakes.
Also, I believe there may be a misunderstanding with the properties of the light wave. Belrad isn't proposing that the E and M planes are at right angles, he's proposing that the courses of field flux are offset. Notice on the graphic that the Magnetic line is at a value of 0 when the electric is at a peak.
This is important for two reasons. First, it implies that a wave maintains a constant energy value (as opposed to pulsing plus, minus, plus, etc.). Second, it is a planar representation of Belrad's deeper idea that the e-m properties do not exist on 'planes' per se, but are actually two (semi)particles in a charge-locked orbit, a quarter rotation offset. To get deeper than that, you'll have to ask him directly.
