Of course it sounds silly now.

It is difficult to describe that there are more dimensions to light from the sun.
Like, how do you say, that this "solar panel" works better with moist ground and leafy growing shrubs under it? It makes no sense to our Modern Materialistic Science. But, if you live long enough, you will hear these words.

Anyway, you have seen experiments with light polarization? Well, imagine that you could get to 100% efficiency in each direction. Just getting more than half, would get you over 100% in today's vernacular.
