  1. If you did boost DC up to feed the transmission lines, it would be a mess and a great expense to step it back down. That was why AC won out all those years ago between Tesla (AC) and Edison (DC).

  2. @painlord2k Oh, you can do it, but it's not easy to step it back down, and it would be more expensive than simply using a transformer. Plus, it would waste a lot of energy, IMO, to do it. That energy is dissipated in heat. It would have to be regulated with large solid-state devices or even large vacuum tubes. In other words, it's a big, complicated mess.

  3. @ No, about the same amount of time. Voltage goes down and current goes up for equivalent wattage. 100 watts = 100 watts regardless, and the time to heat will act the same between two different voltages.

  5.  @randacnam7321  What would your guess be for the highest voltage that one could run a large DC motor at? One could create a large M-G set, where a large DC motor would turn an AC generator, and convert it back that way, though it would not be efficient. One place I worked at had large, open frame, synchronous motors that run on either 2300 or 4160 VAC, but required 250 VDC on the slip rings. We used M-G sets to obtain the DC.

  6. They'll start toppling the traffic and streetlights to steal the copper wire out of the poles to sell before long.

  7.  @randacnam7321  Yea, most large DC motor manufacturers only give a maximum of 1 kV.
