Chargers are an inevitable result of ubiquitous consumer electronics. There are phone chargers, tablet chargers, iPod chargers, laptop chargers, and the extension cables required to support them all. At one stage, it became so complicated that the EU stepped in, passing legislation to make all phone chargers identical. But despite this move, we need a lot of wires to keep our devices blazing away.
Yet wireless power transfer has been around in one form or another since the late 1800s, when individuals like Nikola Tesla began experimenting with the technology and demonstrating its feasibility. Since then, the technology has continued to evolve although never truly becoming a widespread feature of consumer electronics. However, all that might be about to change due to a confluence of events necessitating new approaches to old problems.
