I don't think one could do this in any efficient way.

Doesn’t need to be efficient with that power level.

I'd have thought some kind of simple mating connection would work fine at
a low voltage.

But with your island so soggy, even corrosion might well be tricky.

If you want them on when the gate is open but its only open for a while
then one could use a UPS on the gate with the connection connecting the
charging.

To do power transfer well seems to require HF AC at quite a high current
from what I recall. Looking at the inductive chargers for smart phones
they do seem to have a lot of electronics involved in the detection of the
tuned reception system as well.

But that wouldn’t be necessary when its just a led light.
The solar powered led lights are very simple electronically
and I can't see why the solar cell(s) cant be replaced by
the wireless power source.

The question is, is the use case worth the hassle of building something
big enough.

Yeah, I'd go for a flexible power cable at
the gate hinge end myself. They obviously
work well enough with car doors etc. Tho
that it may be not as convenient to wire up
as at the opening end of the gate for his place.

Another good reason to pay peanuts for a much better server, nin.

I've restored the original list.

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.
