[QUOTE="2cvbloke, post: 451541, member: 199791"] Induction, that's what it is... :D Basically, if you take a transformer like what you use for a charger for your mobile, you have 2 windings around a ferrite (I think) core, 240v in and say 12v out, if you split the two so they can be seperated, then you get "wireless" electricity, you don't need electrical contact in order for the devices to be powered, therefore wireless electricity isn't that difficult... :) OralB have already done it with their electric toothbrushes, keeping the base and the brush electrically seperate in order to prevent any splashes of water shorting the charger out... :) [/QUOTE]
