In today’s world convenience and portability rule. Our appetite for wireless devices is rapidly growing, and with it the need to power these wireless devices… wirelessly. As I began to prepare for this post, I started to think about all the batteries I use on a daily basis. In my car is not only the lead-acid car battery, but also a battery in the key fob to unlock the doors, and probably a few others for the car’s computer that I’m not aware of. Then there is my cell phone, my laptop, my broadband card, and alas… even the tablet I’m writing this on right now!
