    This is really interesting because if this technology was implemented everywhere then gadgets would simply operate like they were permanently plugged in and batteries would be like auxiliary units that would only come into use when in nature. If it's powerful enough maybe they could lay the technology down on the streets and electric city cars could operate without the current autonomy limitations of fuel cells/batteries, and even lose the weight of those batteries entirely.

    Does it have any effect on animals, like frying your brain or anything?

    At the power intensity needed to do more than slowly charge a phone, probably.

    Not sure where people get this idea, wireless power doesn't send electrical current through the air. Maybe they should have called it electromagnetic power as that is what most wireless power uses, an electromagnetic field cause the coil in the receiving device to generate voltage.

    At worst you may find your keys or other metallic things sticking to the charging unit.

    But the electromagnetic field is what fries your brain, just like a microwave oven.

    electromagnetic field is just a magnetic field produced by a few electrons moving through a wire, it is no different than a magnetic field produced by a magnet other than it moves. a much larger magnetic field is produced by the earths metal core.

    as for the microwave, that works by radiation which vibrates water molecules to heat things. this radiation is produced by a magnetron

    You don't get you brain fried when you go in a MRI and that uses a much more powerful magnetic field, you seem to be confusing magnetic fields with radio waves.

    But can you catch it from toilet seats?

    No, but it does heat things up, especially any metal implants

    Like i said a MRI is much more powerful, around 5,000 to 30,000 gauss.
    If we get to the stage of needing LN2 to cool the electromagnets in an inductive charging loop we will have more to worry about than heating up metal implants.

    Such as batteries exploding like a miniature nuke from being overcharged by unheard of proportions?
