Maybe we have a future with no charging cords and just being at home and your phone is automatically charging from your “Wireless Charging Router”.
Sorry if this sounds stupid lol. I like to imagine weird ways we can use technology.
I believe you would end up inducing currents in any metal surface in the house. Causing them to heat up, or if they are un-shielded electronics, zapping them.
Pah. Make your whole house out of plastic and rubber. Checkmate big cable
Rubber is also used in cables
Just move to the forest bro, wood is nature’s plastic
@Randomgal @Quadhammer what forest is available and free to move to
I would seriously doubt it, not because it’s impossible, but because it’s massively impractical.
It turns out that wireless charging is shockingly inefficient. The antennas you would need are way bigger than you could carry practically, and the amount of power you receive is very tiny compared to the amount of voltage you’re pushing through.
A YouTuber I like actually built a setup like this in a recent video.
Not for a full house, but there are per-room solutions on the market today.
The problem is the rule of squares… for the field to be strong enough to charge devices at the edge of its range in a house, it would have to be strong enough to scramble all electronics and possibly cook your food at the emitter.
But one per moderately sized room? Yeah; very energy inefficient, but you can get it installed today.
Ok, blue-skying a bit here…
There’s this YouTube channel I check out occasionally. The YouTuber built a “wireless desk” where everything from the lamp to the mouse, keyboard, and even a coffee warmer were wirelessly powered.
The core of it was a large induction loop built into the desk’s perimeter, paired with some surprisingly compact receiver dongles. Some parts required deeper DIY, like opening up the mouse and inserting a small receiver, but overall it was cool
Scaling that concept up for an entire house is a wild thought… but kind of exciting!
Biggest problem with this is the inverse square law.
Notice: The numbers from the example are pulled out of my ass, but the concept is there.
Basically, if you double the distance (x2) from source and receiver, available power will be 25% (x0.25). If you triple the original distance (x3) then available power will be 10% (x0.10) (Not the real math, but it’s along the line)
If you can pump out enough EM to cover all areas you’ll need, but not so much that it’ll fry devices closer to the source, I don’t see why you couldn’t get this to work in theory. I just wouldn’t want to pay the power bill required to overcome the EM field drop-off.
Biggest problem with this is the inverse square law.
unless we did it with fricken lasers!
That’s actually a thing. I saw a video reporting on some trade show and they were able to do something with a laser to energize a small device. Something a bit more intensive than a led but not by much.
Sure just go ahead and stick a toothpick in the latch to your microwave and hit go.
Real answer right here though: https://www.youtube.com/watch?v=n42nWBy3lWI

Not stupid at all. I think I read that Disney has something like that for charging communications equipment at the parks. (I could be remembering wrong, I am internet brain-addled.) You know the crazies would hate it, though. Smart money says that there’s an entirely port-free iPhone in the next five years.
It’s reasonable to be skeptical of any truly high powered EM source directly in your living space. High powered EM interactions with random objects can cause unpredictable rectification and remodulation as complex as any fluid dynamics problem. You cannot model what would happen in such an environment. I wouldn’t call people who balk at it crazy.
I don’t think it sounds stupid at all! I looked up some info on this and it appears the technology already exists in that RF and Infrared chargers can charge a device across the distance of a room already. I would worry about the safety aspects of the average consumer having access to some kind of wireless charging “router” though. With wifi if someone sets something up incorrectly the worst that could happen is that they just don’t have good wifi, or they inadvertently give all the houses around them access to it, or someone hacks into it and steals their data. What would happen if someone manages to set up a charging router incorrectly? You could have overheating issues that could lead to battery degradation or even injuries. If some nefarious person gained access to it they could tell when Aunt Sally is using her rechargeable dildo, or they could make someone’s TV remote blow up in their hand, or set someone’s phone on fire in their pocket possibly?
I’ll be honest I’m no expert on such things so this is all speculation on my part. I’m just very paranoid about this kind of thing. I suppose such a router could be restricted to only emmit a safe level of charging power but wouldn’t that mean some items charge quickly while larger items take hours or even days to get a full charge?
Basically, yes, depending on how much electricity/energy you’re talking about
Yes, but it’s incredibly slow, wasteful and, unsafe. Companies have tried making hardware that does this at a room level, but have largely failed because it’s so wasteful and slow.
Eevblog has a bunch of videos debunking these things https://youtu.be/2rSQnRV5ztI
The energy in a wave is inversely proportional to distance squared. In other words if you double the distance you get one quarter of the power.
For information transfer like wifi this does not matter as long as it’s enough to be detected.
For power transfer this becomes a huge problem quickly because it’s the energy itself that is being transferred.
There’s a video about somebody hooking their barbed wire fence running under some transmission lines up to a load. And yeah, it works.
Can people feel in a strong electromagnetic field? Is it safe?
