There are a lot of interesting stories around at the moment concerning power/electricity.
For example this story about Google getting involved in devices to monitor power usage in homes. or this demo of WiTricity, wireless electricity in its infancy, or this story about wind power in the middle of the oceans.
I have mentioned before on this blog some of the issues we face with regards to power consumption, but it's nice to see some major moves in this area.
Perhaps my comment about 'GooglePower' wasn't so far-fetched after all??
WiTricity, in particular interests me a lot, as it was talking about specific resonance, which made me wonder if the 'user' of the pad could have a specific resonance and the pad would respond to a range of resonances, i.e. you could identify who was consuming energy (the device). If you then stuck a mediation device on the pad you could allow people to automatically recharge and have it billed to their account. Actually might be a lot easier to do it with RFID, if the Near-field communication is not disrupted by the magnets.
Either way, there would be a fairly big market in restaurants/coffee shops etc for people to recharge their devices while they eat/drink/get transported from A to B.
