Found! Power Spots are confirmed!

[Faulce]

Chronopolis and the Dragonians originated the system, and El Nido is bound to the success of the heroes of time. They wouldn't have existed in Chrono Trigger.

Yes, but if the elements were formed naturally, Crono's success wouldnt matter - the elements would be found in and around power spots.  
Where are the power spots on the Zenan Continent? Not sure, but there has to be at least one.  The few places I can think of are the Heckran Cave, Fiona's Forest, Volcanic area around Tyrano Fort, Sun Keep.

The gigantic elements of each color found towards the top of Terra Tower are probably akin to a large-scale model of the everyday elements.
Also the Chrono Cross is definately fully recognizeable when you get it.

Just contain it and go for simplicity. There is no mention of elements or power spots in Chrono Trigger; the only things of this kind are the Rainbow Shell and Sun Stone, artifacts imbued with planetary energy (no color or anything). Chronopolis devised the Element system by dividing up the Dragon God according to colors; it was arbitrary. It then terraformed El Nido, meaning it was responsible for the placement of Power Spots (solidifying the case that they aren't natural (in the sense that they arose out of normal geo...something) and were part of El Nido's paradise). Chronopolis also apparently engineered the concept of the Element Grid for use by non-intelligent species and humans alike, and made everything compatible. The Dragonians then forged and developed them over the years. It is thought that one of the reasons Porre takes so much interest in the little archipelago of El Nido is because of Elements and their easy activation. (In other words, Chronopolis/Dragonians created Elements, engineered El Nido to support their development, and made them in El Nido for years undisturbed.)

But the Chrono Cross is a special case. It's a mix of all the other elements, and one can't necessarily determine what the ingredients look like from looking at the final product. Example-- table salt: you can't just look at table salt, and figure out what Sodium and Chlorine--the components it's made out of--look like.

Just as the Dragon God is sort of a generic, all-encompassing planetary power. Though the Chrono Cross too is a blend of the Elements, it also has root in ancient, singular artifacts.

Ah, but what if the Dragonians brough this technology/technique to the Chronopolitans? We can't really say that it wasn't the Dragonians that influenced Chronopolis rather than the other way around, now can we?

[razor's edge]

Even if the Dragonians were the ones who originally had the elements, Chronopolis defeated them and then incorparated the Elements and Dragonians into El Nido.

I already thought that it was the Dragonians' technology first, anyway.

Electricity as we use it is NOT a natural occurance. It's generated.
DC is naturally occuring, AC is manmade.

Lightning is DC.

We don't "generate" energy, we simpley take one kind of energy and turn it into something else. Like Jane from "Speaker for the Dead" said: "That's why I love you, you can do anything as long as I organize the circumstances for you." (Or something to that effect).

Technically We still "generate" electricity in the same way we "create" plastics. It may require using one thing to make another because you are right energy can not be created or destroyed only changed or transfered.. but the energy was not electricity until we got a hold of it.. meaning we generated it.((sorry for the post in a dead topic..))
