4 The concept of transfering energy without wires is pretty old. You can even
5 have it now, with RFID_ for example (I even have a mouse__ that uses no battery,
6 the pad transfer energy to the mouse using RFID_; very good mouse BTW).

10 But `Eric Giler`__ presents a nice new concept in wireless electricity (the
11 marketing name is *Witricity*), because other kind of wireless energy transfer
12 I saw has very little power (to avoid frying your brain ;). This one works
13 using a magnetic field instead of radio waves, which makes possible to transfer
14 bigger amounts of energy without harm.

18 In the video you can see how it powers a big LCD screen for example. I don't
19 know how efficient this will be. At first sight it looks like it would waste
20 a lot of energy, because the magnetic field generation will be using energy all
21 the time, even when there are no devices using it.
