It sounds too good to be true, and there are certainly reasons to be skeptical. There's a working prototype (needed by the US patent office), but we've yet to see a practical demonstration -- we've asked for one and will let you know if we get it. Also, Radient is planning to license the concept to device makers, rather than designing physical components it can sell. It's easy to promise a revolutionary product if you're not the one who has to mass-manufacture millions of units. If the reality comes anywhere close to the hype, though, the invention will either extend the battery life of phones or allow for smaller batteries without taking a hit to longevity.
