I was going to suggest a series of

How about if I mount a magnetron on a big satellite dish and point it
at a sealed container of water bolted onto the gate? The water boils,
powers a little Mamod steam engine that turns a dynamo which charges
the battery. Simples.
Why not take one of Harry's solar panels, silver your satellite dish to
reflect and focus a floodlight onto Harry's panel on the gate?
Yes, that would work. Design and build a tracking device so it follows
the sun!
