the gravity lamp works with an ass weight. It is the passenger of this boat who will have to do the mechanical work E = mgh, to then produce the electricity that will be produced thanks to the small accumulated mechanical energy, that is to say not much.

So mount the gadget at the top of the mast or "band" a spring with a crank ... even "work".
As for the living room or church clocks, there was either the spring band or the weight to go up ...
For very very low power, no problem. The miracle in history is the LED!
But when I think of all those who ride on flat bicycles, raise masses, etc ... There, the powers are of another order of magnitude 10 000 times more!): On a bike, qu'elqu one of a bit sporty rides on 300 W (a trained heart can do 150!). There is some recovery to do !!!!
