The concept of transfering energy without wires is pretty old. You can even have it now, with RFID for example (I even have a mouse that uses no battery, the pad transfer energy to the mouse using RFID; very good mouse BTW).
But Eric Giler presents a nice new concept in wireless electricity (the marketing name is Witricity), because other kind of wireless energy transfer I saw has very little power (to avoid frying your brain ;). This one works using a magnetic field instead of radio waves, which makes possible to transfer bigger amounts of energy without harm.
In the video you can see how it powers a big LCD screen for example. I don't know how efficient this will be. At first sight it looks like it would waste a lot of energy, because the magnetic field generation will be using energy all the time, even when there are no devices using it.
Here is the video:
