We have wireless communication everywhere, and will one form of wireless power transmission soon also become common?
Doing everything "wireless" has been a long-standing dream for over a hundred years, and some of that dream is reality. I see three categories of doing things wireless:
Communication: now fully realized, via radio, TV, Wi-Fi, and satellites; the list of ways we communicate without a physical connection is pretty long;
Power transmission over distance, envisioned by Tesla: not here, may never be, despite some impressive demonstrations, as the laws of physics which work against it are pretty fierce (see MIT's "Toward more efficient wireless power delivery";
Short-distance power transmission: the jury is still out, but lots is happening.
Let's explore that last one more closely, in the context of three developments:
You can get accessories for your cell phone, smart phone, and similar devices which implement wireless recharging in conjunction with a special flat, inductive pad.
I'm don't know of any credible evidence that cell phone radiation causes any harm. If you know of any studies that have passed credible peer review that do show a link, I'd love to know.
As for Inductive charging though, remember that EM fields fall off at 1/r^2 (pretty fast), whereas magnetic fields fall off at roughly 1/r^3 (super fast). That's why refrigerator magnets hardly do anything once you get them 1-2 mm away from the fridge.
As further evidence for the lack of danger are MRI machines. There, you're sitting in the middle of one of the strongest magnetic fields on the planet, and again, nobody seems to be harmed by them (except by the stray piece of iron that flys into the machine)
Of course, we need to keep vigilant for dangers, but a few charging pads around the house hardly seem like they'd pose a threat to anything, especially if they are only on when they sense a unit to charge.
cell/smart phones, laptops/tablets, MP3 players...
Yes a winner
Everyone hates lugging and plugging in chargers.
All others like TV's...
A universal one that my cell phone, laptop or whatever can be thrown on to a desktop/dashboard... and get recharded will be a winner.
I do not want 17 different inductive chargers all over my house, office and car.
This would not be much better, only saves the hassle of plugging in
Wireless charging is always been an interesting topic. However whenever I hear about wireless charging I got worried about its impact on human. There is already a known impact high energy cellphone signal impact on human body. The energy out of cell phone is much smaller than wireless charging energy we are talking about.
