That's why your definition is insufficient. OU is relative to the system that you are considering. So here is what I propose to add: We consider an apparently closed system and we apply your formula to it: delta energy = sum(energy outputs) - sum(energy inputs) + final stored energy - initial stored energy If delta energy >1, we have OU for this system as defined above.
OU can be due to:
- 1 energy out of nothing (perpetual motion of type 1)
- 2 energy from ambiant source that can be replenished by the used energy: typically heat (perpetual motion of type 2)
- 3 energy from an unknown source crossing the boundary of the apparently closed system. When the source is identified and we see that it is depleted proportionally to the apparent extra-energy, the device becomes conventional and without OU if the system is defined with the source included.
Imho type 1 is unlikely. Type 2 is the more interesting because the most part of our useful energy finally ends in heat (light, TV, PC, cars...) and so, the process is looped by the return of the used energy to the ambient source. Type 3 is pseudo-OU. Nevertheless it's interesting if the source is not extinguishable at a human scale, for example the sun. Type 3 is not distinguishable from type 1 while the source remains unknown.
There is a very real type 4. which you missed out, that is chemical change or electro chemical change. This is very real, the first part "chemical change" may not be possible to loop back!! but the second part, electro chemical change most definitely can. We are only just touching on the possibilities with this, and it is OU which can be used. We are still learning about electrons and their smaller parts, electrinos, which have a very high energy state once triggered and can be triggered with less energy than they can give and be harvested. Type 2. has just been done by MIT with their cooling LED, though I think they are not the inventors though they like to think they are the only inventors . We have the same old arguements, if we spent the time doing rather than arguing, then we just might see a lot lot more of what is deemed to be impossible Mike
