What is it about?
With simple non-reciprocity consideration of a loop (nano)antenna the mystical functions of a bacteria light harvester are unlocked. Non-reciprocity is a fundamental requirement in antenna theory otherwise there is no net gain of power received or emitted.

Why is it important?
For centuries people working the photosynthesis are chemists. They are unfamiliar with nanoantenna developed since 2000 by physicists and engineers. For decades people called the light harvesters antenna, but no one ever considered them as antenna seriously. Furthermore, chemists do not even believe a dielectric can be used as an antenna, which is not even dielectric. Most people doing "biophysics" are actually doing biochemistry. There is no physics in their research. Our antenna acquire their properties through geometry. There are real physics inside. Presently people doing biomimetic solar energy harvesters are considering only examples from animals. Photosynthetic light harvesters are examples from the plants and bacteria.
