> You have plastic insulator around your electricity wires to prevent you getting electric shock. Is that a fix or a workaround? Because a fix would be to actually have continuous current at max 12V as power lines. But that's not economically viable.
Your examples are wanting.
Wires are also insulated to stop them from touching each other, not just to prevent electrocution. A 12V wire touching another can definitely result in sparks and fire. It can even amputate your finger if you bridge with your wedding ring.
In virtually all situations wire needs insulation - it's a feature not a workaround.
- unnouinceput 6y agoDid you know that when they first implemented electricity they just buried them pinned with nails on wood, no insulation? Back then insulating wires was more expensive than just eating energy losses via running current. Like I said, it all comes down to economics.
- mikewarot 6y agoI'd really like to see evidence of this... if you bury wires directly, the voltage will speed corrosion to the point you won't have wires after a few weeks at best.
- MagnumOpus 6y agoBuried them behind drywall and ceilings, not in dirt. Look up https://en.wikipedia.org/wiki/Knob-and-tube_wiring https://en.wikipedia.org/wiki/Knob-and-tube_wiring that is in some cases operational even after a century.
