What's wrong with it?

  Maybe he thinks it should be 'kiloWatts'. CamelCase impairment?

  I can't see the problem either. I don't think it's a capitalisation problem; when using 'Watt' as a name, e.g. James Watt, you need to capitalise. But the unit is 'watt', with a lower-case 'w'. The symbol is an uppercase W. Reference: Table 3, in "NIST Special Publication 330: The international System of Units (SI)", Taylor et al (2008). Nor do I think there's a problem with confusing energy and power, as there currently is in the original title. So, what's the problem? Jaquesm's "And you still got it wrong" comment is unhelpful because it doesn't identify a specific problem. Maybe he feels that the sound doesn't actually come from the cable. Or maybe the cable isn't carrying 50 kW. I don't know. Maybe there is an obvious problem I'm missing.

  I believe it's actually the arc producing the sound, otherwise the cable would make the noise regardless of the presence of the arc. Whether that's what jacquesm is referring to or not, idk.

    Yes. The arc is what causes the AM modulation to be translated to moving air at the same frequency as the modulation because the intensity of the arc changes rapidly. Since this is AM you end up with intelligable sound (for an FM station this trick wouldn't work).
