Yesterday, I was thinking, what if we invent wireless electricity, where you don't to plug any power chords. You just come to the vicinity of a wireless electricity source, and all the devices you are carrying get charged. We won't need any power sockets in the home or office, and we won't need to plug in our phones, computers or PSPs. We won't even need to replace the batteries on the remotes or wall clocks! I say to myself: I don't believe this hasn't been done yet. Nice Dreaming.
Well, voilà! About an hour later, my RSS reader gives me this: MIT Wirelessly Powers a Lightbulb, and my dream comes true. What a coincidence!
They call it WiTricity. "The MIT researchers successfully demonstrated the ability to power a 60 watt light bulb from a power source that was about 2 meters away. The setup powered the bulb on even when the coils were not in line of sight. The researchers plan to miniaturize the setup enough for commercial use in three to five years." I'll wait.
