  If you were paying attention how abpout reviewing a point with me. In Power
Transmissions which Like would have the Least Losses and Why, A 500,000
Volt 60 Hertz System or a 500,000 Volt Direct Current system.
  Back in my fuzzy brain I seem to rembember something about there being less 
losses in a Very High voltage DC system but can't rembember exacticaly why.
