DC transmission is VERY inefficient. Just Thomas Edison.
PS The war has cost us ~600B. When GB took office we were 4.5Trillon in debt. Now we're ~10Trillon in debt! I here people complaining about the cost of the war all the time & I must say I'm sick of it. We can debate whether the war is good or bad, just or unjust, but the cost of war is irrelevant. If we are in a just war(I don't think Iraq is, not since we stopped LOOKING for the WMD's) if that just war(ie. WWI, WWII) costs us 15T if our way of life is under attack the the cost is irrelevant. What I want to know is where did the other 4.9Trillon go?
