Earlier message from Chad: "DC ???? less loss ???? must be super wire. Is the dialectric sheeth measured in feet ???" <br /> <br />I'm no expert on electricity. The issue was raised locally some years back when the State Power Authority wanted to string 782kW towers through our little town. We already have two lines of lower wattage towers! <br /> <br />Further south, they convert to DC, to run through the tonier sections of Westchester County and into NY City. <br /> <br />As I understand it, DC is run using shielded cable, which probably reduces radiation loss substantially. Somewhat like why your cable TV (and Internet) uses shielded cable. <br /> <br />At our town meeting, I suggested they run underground DC all the way from Niagara Falls, and connections to Canadian hydro-power. I thought they could use an existing ROW - the median of the NY State Thruway. Then, maybe at least some of the towers would no longer be needed. Which could return the ROW to private ownership, and reduce that portion of existing costs. <br /> <br />I was simply told, "That can't be done." <br /> <br />Well, then maybe RR ROWs could be used. <br /> <br />It's all economics, and I don't know the cost-benefit numbers. As with everything, it's also "all politics!" <br /> <br />Best... <br />Chris
