Why not use DC and put the lines underground?

When using pulsed DC for fishing, the pulse rate and the intensity of the electric field strongly influence the size and nature of the catch.

Using DC fast charging, the battery pack can be charged to 80% capacity in about 30 minutes.

The 2N series, which were introduced later when 3N sales went down, used DC with negative current on one rail and positive on the other.

Ordinary cars use nominal 12 V DC and may need to convert this to drive equipment.

The Edison system used direct current, or DC.

The earliest systems used DC as AC was not well understood and insulation material for high voltage lines was not available.

Some cities continued to use DC well into the 20th century.

Electronic circuits use DC to provide power for the transistors and other components in electronic systems.

Early electrification systems used low-voltage DC.
