Well, it is difficult to choose which turtle! This is all a little bit difuse for sure.

Why the focus on electricity and magnetism?

An alternative is pendulum clocks that can be powered by gravity and initiated by the user moving the pendulum to one side. A key part of the mechanism is an "escapement".

Or the turbines in a hydroelectric dam that are ultimately powered by hydrogen fusion and initiated by the user turning a valve in a penstock.

Er what?

Oh, you mean ultimately ultimately!

Thanks for everyone's replies, gained a much better understanding, and I'll watch the videos on the way to work tonight.

Sorry for what appears to be an 'flaming' post.
Transient response of system is a broad field on its own, with either discrete lumped elements or with a continuum medium.

The great R P Feynman gave this some thought. The first part of this interview is wonderful, in my opinion.
Please give it your attention.

Great video! A physicist who realizes the value of imagination and visualizing the currently unviewable parts of physics.

Thinking something people would really enjoy is a 'Feynman forums' where physics people can team up with visual artists to 'explain like they're Feynman'.

Visuals for the travel of energy from the net motions of electrons into fields could've been such a benefit to his explanation, and the types of visuals today are really advanced and so much more available to everyday people.

Seems totally reasonable, not flaming at all.
