No, what you really need is an understanding of wireless power transmission and non-ionizing radiation. Hint: There's a reason this requires METAMATERIALS to work over any reasonable distance.

Non-ionizing radiation will change the temperature of water (or your body) if it's in the way. And testes need to be closely temperature-regulated, so this could be a real issue.

  Microwaves yes. But inductive coupling? No - it won't even interact, which is what this article is about.

    Would be a problem for metals. You really can't win when you're talking about high energy radiation.

    Excuse me. Inductive coupling means a couple of inductances interact with each other. This is the reason it is called "coupling". And yes, this interaction means photons, depending of the frequency of the resonator of higher or lower frequency. They use a medium, a channel, the most efficient one is ferrite, but it could be the air, that usually it is very inefficient because the electromagnetic radiation escapes and is absorbed by other elements or just dissipated. You could improve efficiency making it use resonance, that is you trick your design so in normal circumstances you reuse the electromagnetic energy that is reflected by the geometry of the space. The problem (of all open systems instead of closed circuits)is what happens when your body acts as a lower impedance for this radiation than the medium. It could in fact absorb a big amount of energy on a very small amount of time. Geometry of the body is very complex, small parts of your body could resonate with some frequencies, and when there is noise like in transitories you add lots of frequencies.

      FWIU, inductive coupling uses magnetic fields to transmit power. We use magnets all the time and I don't recall anything harmful coming of it. Can you point us in a direction that would challenge that statement?

"No, what you really need is an understanding of wireless power transmission and non-ionizing radiation." Like you do? Do you understand non ionizing radiation? Some people are so ignorant, that they don't even know what they don't know. I can kill a rat with non ionizing radiation. I could introduce it on a microwave or put it under a laser, or in the oven(IR). With enough energy density, I could create devastating effects on any living organism. Nature protects against natural sources of radiation, like the light of the sun, but does not protects about artificial ones, it is very simple to blind someone with a IR laser she does not see. You can use non ionizing radiation to make resonate the electric nervous systems like the US army is testing, with enough energy it kills you(we need electric operated muscles like the heart and lungs to operate to live), and lots of other funny things.
