After doing a bit of research it looks like it is do-able. It relies on the inductors on the Tx and Rx sides being resonant. Certainly for the 1 to 1.5 cm spacing involved the efficiency should be quite high. Here in Spain PP9s are not readily available so I have to order them from RS along with some high power MOSFETs to try out the idea. The ideal solution once these batteries go down would be to replace the internals with 6 x AAs and fit the base of the batteries with an inductor and other internal circuitry to enable charging and/or radio operation. This would require a base panel into which the turntable slots with 2 inductors in the base. A sensor would measure the output current in order to ascertain the charge status.
Once I get the MOSFETs I'll do some experimenting. More to follow, maybe a new thread would be an idea.
