Funny enough after posting the above commnet I read that Stabucks is implementing a pilot program in Boston of 17 locations offering wireless mats...so I am wrong and behind ;-)...but what devices have that wireless charging capability implemented?
Perhaps...but using your example of Starbucks with a charging mat: is this going to be one mat per cafe? that might create lineup to use it...many mats?...what if the mat doesn't work? (outlets usually do work)...what if people start spilling coffee over it? who owns the mat, does the cleaning? what happens if it gets stolen? there are many operation issues...as far as health is concerned what if kids start sticking their fingers between the mat and the device to be charged? who is liable if something happens? Starbucks? again, many, many safety and regulatory issues to be resolved...Kris
@kris- thanks for your comments/questions. I think the idea is--still admittedly a long way off--you don't need to carry the charging pad, because just about anywhere you would go where you might expect to plug in, there will be a charging pad(s) there for you to set your device on to recharge. If you go to Starbucks, you can slap your phone down on the pad (same if you go to your buddy's house, etc.) In your house, you will have several to choose from. This of course requires some standardization effort which is still looming.
As for health risks, I can't speak to that. I believe that is an issue if you are going to be broadcasting over distance. But if the device is in close proximity, I don't think this is a problem.
thank you Dylan, but this is not as simple...you don't need to carry the charger but you need to carry the charging mat, is that really that different?...and the charging process is less efficient than by wires so you are losing the energy, this is not green, not so cool...what about health risks? you are broadcasting lots of RF power, much more than for RF communication, is that a problem? Kris
No need to carry the charger, no need to look for the charger, no need to untangle the charger, no need to get mixed up on which charger to use. Plus, with one pad supporting all of your devices, you don't need to tie up 10 electrical outlets. It's clear to me this is the way forward. In addition to the convenience, think about the reduction in expense and materials use associated with making far few single-purpose charging cords. Bring it on, I say.
"proponents believe 2013 could be a big year for the technology." - wasn't 2010 supposed to be the big year of wireless power? and 2011? and 2012?
I even remember being in an Intel Developer Forum keynote in 2009 and hearing Rattner talk about how we were on the cusp of wireless technology.
Hell, Tesla thought we were on the cusp of it almost 100 years ago....
Wireless power needs to step it up already...
