I want to put some LED lights on my sliding gate. I wondered if I could
power them inductively, with a power 'transmitter' fixed to the gatepost
and a power 'receiver' on the gate, positioned so when the gate's shut
they are close together and the LEDs come on. The power requirement of
the lights is 24W at 12VDC. The positional accuracy of the gate is good.

Should work fine. Dunno how buyable it is tho.
