"With its concentric broadband antenna rings, it harvests the energy of electromagnetic noise from Wi-Fi, and similar signals and this way also reduces the level of e-smog pollution in your environment."
This is nonsense.
- a8da6b0c91d 11y agoWe hope it's nonsense. This idea that constant exposure to EM is without consequence is unproven. If your immediate response is something about "non-ionizing" then you know nothing about the many animal experiments that demonstrate behavior and biological effects from magnetic fields and EM exposure.
- gubby 11y agoMy immediate response is that putting some tiny rings of metal on a window somewhere in a room will not somehow absorb and decrease the amount of EM in a room by any measurable amount, harmful or otherwise. Additionally, the amount of energy that could be harvested this way is a few orders of magnitude less than what would be required to oscillate a window with enough force to cancel sound.
