Ok, but if you insist on having minds blown by it, then consider this:
Wifi is a way of sending power (watts) over a given distance through the air, right? And this power is transmitted in the form of microwaves.
Let’s look at a hypothetical. Let’s say you wanted to power your microwave oven wirelessly. Let’s say you have a wireless sending unit for the power that’s needed on the counter on one side of your kitchen and your microwave oven is on the other side of the room. Only, the thing is, transmitting the needed power across the room will consume about 50% more energy than the device needs to operate. Sending power through the air is a very inefficient way to move electrical power, air is normally considered an insulator. IOW, your 1000w microwave oven will require that 1500w be sent through the air to run it. So let’s put that into motion. Your oven will indeed work, but, tell me - how safe does anyone think they will be standing in a room in which food on the countertop begins to heat up and metal objects in the room begin to arc...now that you’ve just turned your kitchen into a 1500w microwave oven.
Obviously wireless technology is going to have to be limited to very low levels of power in order to remain safe. But, the question is then two-fold: 1) How do we determine what a "safe" level of microwave exposure is, and 2) Who are we going to fully trust with setting that limit - the wireless industry that can make far money the higher that limit is, or the government that is lobbied hard by that industry?
