There used to be a series of sayings.. "You know you're getting old when....." followed by something like ".....you bend down to tie your laces and wonder what else you can usefully do while you're down there"
Today I realized how quickly one can get left behind by the pace of modern technology - blink and you've missed it! Earlier, I casually picked up an electric toothbrush belonging to a friend. It was seated onto a small plastic pedestal which was wired into the mains, and obviously contained a charger. The connection between the brush body and the charger was by means of a solid plastic spigot on the charger being entered into a socket in the base of the plastic body, there was no metal to metal connection of any sort.
I assume the body contains a rechargeable battery. How is the current passed into the brush body to recharge the battery - by induction? Do any other products work this way? How much current can be transmitted? How long has this technology been available?
Sigh......I have absolutely no idea how this thing works, what else have I missed? Will the horseless carriage catch on? Answers on a postcard, please...... :}
