This is referring to BIG power distribution; Megawatts up to 800kV extended over thousands of km. Besides that, the cost of distributing 50kHz power over twisted pair shielded wire would be cost prohibitive. HVDC can (and is) also be buried on land or on sea beds. China and India all have projects in the works to implement HVDC distribution over their vast continents. Once again, the US could be saddled with obsolete, legacy technology - he who has the best tools wins!

Nice idea but 50KHz would increase skin and proximity effect losses to unacceptable levels. Plus all rectifying would then have to employ ultra-fast rectifiers, meaning that most input rectifier stages presnetly in existence would then be unusable
