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.

Same idea

A FAQ suggests that the MAXIMUM spacing between coils is 10mm
? and damage may occur when there is no load so when the coils are
not aligned (maybe even by a small amount) when the gate is moving the
whole system may have to be instantly switched off.

Thats a lot more power than he needs tho.
