The basic idea is simply that when you have a powerful source of negatively charged electrons, they pass that charge on to the air around them, "ionizing" it, at which point it flows away from that source and toward — if you set it up right — a "collector" surface nearby.
|
|
The author of the post also said that, in 2015, a group of more than 200 international scientists sent an "appeal" to the United Nations and the World Health Organization "expressing 'serious concern' about the non-ionizing electromagnetic field (EMF)" that is emitted by Bluetooth devices, such as AirPods.
