## Emergence
**Emerges from:** [metal](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-metal.element), [piece](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-piece.portion), [carrying](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-carrying.transporting), [current](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-current.fluid), [use](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-use.application)

**Through:** The metal portion carries the flow of current through controlled movement.

**Novel properties:**
- controlled conduction path
- directed energy transfer
- continuous contact medium

## Examples
- The aluminum-conductor steel-reinforced cable of the 1974 Itaipu Dam power transmission line carried 6.3 gigawatts across 800 kilometers. *(engineering)*
- The copper cable in a 2017 MacBook Pro delivered 100 watts to charge the battery at up to 20 volts and 5 amps. *(computing)*
- The High-Z submarine power cable linking Norway to the UK, completed in 2021, conducts 1.4 gigawatts of alternating current through the North Sea. *(economics)*
