Any reason something that is designed to wirelessly charge LiIon batteried phones, couldn't be adapted to wirelessly charge sabers? I'm imagining is the rechargeable toothbrush style, where a plastic indent in the pommel is the site of the induction coils. You'd need to make both the charger and the receiver (with something like this, stepped down to 3.7V).

Anybody know if you can take the above linked coils and resize them (wrap them in a smaller loop to fit inside a saber?)?

I'm guessing the main problem people would have with this setup would be the low speed of recharge. 500mA at 3mm isn't going to recharge a saber in an hour, but maybe over (a couple) night(s)?

Has it been done? Could it be done?
