Yes, but with enough juice for a light bulb ...

Isn't a light bulb basically all that a lighthouse needs?


Not a very powerful light bulb, though, according to the figures on WP.
Even allowing for it flashing on and off, so it's not powered all the
time, you are looking at a couple of hundred watts, maximum.

in most light houses, 'flashing' is created by a revolving lens assembly.
That revolving would need a motor - more power.

True, indeed. So, I don't see how one of these generators could produce
anything like enough power? They seem to be in the range 10-100 watts.

Solar power makes more sense nowadays, even with redundancy built in to
allow for degradation due to dust build up.


Solar power makes no sense at all. Its completely unsustainable
