The idea is to be able to have on demand power for small devices dispute power outages and what not hence why mechanical energy is my approach

Thats the general idea I'm going for- stored mechanical energy converted to electric, the problem is something like your mouse trap example would provide energy for just a brief moment where i would need constant power output for about an hour :/

A spring or coil can be rewound over and over again whiteout the need for external electricity. Batteries only have one use or require existing electricity to recharge them. And if i wanted to store it for a day the design could easily be changed to store it for a few months or even a year...

lets say i wanted to store it for a day. I wouldn't mind being able to go longer, but a day would be pretty ideal.

If I'm storing it in a spring or a weight i should be able to store it for a very long time, especially if i change the design to use a falling weight, then i could store it indefinitely.

I don't need to store all that much energy, only about 5v. Its a really small amount but it needs to be a constant power output for slightly more than an hour. I could modify the rest of the design for half the time but I would really rather not. I figure releasing mechanical energy from a...

The elastic rod idea is interesting but I feel as if the constant stretching and relaxing of the relaxing of the elastic would eat up more energy and eventually warp the elastic. I hadn't thought of a governor though, that would be a pretty good idea. I want to create a mechanical battery of...

But a watch releases the energy in spurts, the second hand for example repeatedly moves forward and pauses. I'm looking for a more constant motion

Is there a way to wind up a spring or coil to store mechanical energy and then release that energy slowly over a longer period of time instead of allowing the spring to release rapidly all at once?

Would this slow the approach to equilibrium or, if done correctly, avoid it? and couple how? im assumeing by "thermodynamically favorable" you mean exothermic?

entropy is when you convert the energy into mechanical work right? I am not doing that though. Then again I'm not sure what entropy is completely to begin with haha What kind of work would need to be performed on the system? Are you saying that with this "work" the system can be moved away from...

im sorry i meant to say "way" not "was" is the energy lost in another way other than heat energy; and also if this energy loss could be compensated would the system then avoid equilibrium

Ok fine last question: if the energy lost as heat was re added into the system with another source, would it work or is it energy lost another was as well?

I won't be converting the heat energy into any form of mechanical work so entropy shouldn't be a problem. lets say the first reaction is exothermic, while the second and third are endothermic A+B->C+D C+E->F+A D+F->E+B then take the entire system container and magnetically suspend it in a...

Second thought: Or does it depend on the situation?
