This is a fractal tuning fork, 3d printed so that its vibrating behavior is optimized. The material, shape and size all could be varied adaptively to maximize its vibratory energy storing cspability. So it would start as a hard round blob at one end and gradually become an infinty of springy branches at the other end. If not a battery at least it would make a cool bouncing tree statue.

Actually maybe this should be the inside out version of this -- a hard sphere with adaptive springy branches that go toward its center, attached to another hard sphere at the center - so an adaptive gyroscope.

I read this as Turing Fork Battery, which is a series of magnets and coils secreted in the handles of cutlery of your local maths faculty...but you could do the knives and spoons as well.

Best part of the idea. ^
