Comment; For those of us with sensitivity to electromagnetic fields, the expanding “Internet of Things” (IoT) will require electricity to power all of the myriad devices attached. These devices will not only communicate with the world wide web (www) wirelessly, but will also receive electrical charges electrically–by manipulating magnetic fields. Oh joy! I see a LOT of folks being harmed in our future–yet safety studies of implentation are sadly lacking!
