This is one of those little SF technologies, like the flying car, that has long been dreamed of but has never happened. It’s easy to understand why the flying car hasn’t — safety concerns, security concerns, and price. But the only reason I can come up with against short-range wireless power is the chicken-and-egg problem: no one is going to create electronics to take advantage of one of these sheets until the sheets themselves are ubiquitous, and no one is going to start mass-producing the sheets until there’s a large and demonstrable demand for them — which won’t happen until there’s a large number of things that use them.

As nice as this kind of thing would be, it’s not going to happen until someone comes up with a cheap transitional technology, or some extremely popular piece of electronics incorporates it. Such as… the iPod? Oh, Mr. Jobs…
