An interesting article about wireless power. Basically these MIT students made one coil of copper wire to transmit "magnetic resonance" (MHz) 7 feet across a room to another "receiving coil" to power a light bulb. This works a lot like an opera singer breaking a wine-glass that is receiving energy from her vocal frequency- except instead of harmonics, it's magnets. The cool part about this is that, unlike current electro-magnetic power-transfer, the power of this "magnetically coupled resonator" travels great distances and doesn't RADIATE and get lost in space creating RADIATION that can harm [human] organisms. Instead the power that isn't gathered by the receiving unit remains localized with the sending-unit.
http://www.gizmag.com/go/7418/What does this mean to you? how about never having to plug in your "feather-light/paper-thin" laptop that doesn't even need a [heavy] battery or cord! Cell Phones are pretty thin now, but you could literally have a Zoo-lander-sized phone here.
Pretty awesome stuff!One of my school projects was Starbuck's furniture that had a fold-out table for your laptop and the table-top transfered power to your computer. Great idea, but this technology will quell whole "fear-of-cancer" thing that comes with current inductive power-transfer.
