This device is overunity during acceleration – not while cruising. During cruising, it's merely 1ppm efficient wasting most of the energy acquired during acceleration! Overunity is a vague term describing a behaviorial characteristic. A more precise term is unidirectional DC impulses. These are longitudinal magneto-dielectric waves wasting no energy in their propagation at π ÷ 2 × C. In other words, at 57% faster than the speed of light! {Java CircMod}
