We're getting off-topic from British vs. American English here guys; so I'm changing the subject line. If I recall correctly ... High Voltage (hundreds of thousands of volts) DC transmission is possible, but it generally requires AC transformers to get the voltage up, then rectifiers to convert the high voltage AC to high voltage DC. An alternator is used at the other end to convert the high voltage DC to high voltage AC, then an AC transformer is used to step the voltage down. So, long distance DC transmission is still not feasible without AC on both ends. DC generators do not generate DC voltages anywhere near high enough for practical long distance transmission, and practical transmission voltages are impractical utilization voltages. Hitching his wagon to DC was Edison's biggest mistake. DC cannot be easily transformed from low to high voltage or vise versa the way AC can. -- .''`.
