You are correct, it was late and counld't see. However, you're still not providing any data here, you spewing numbers with nothing to back them up. Math please! Plus, the major point I'm trying to make is that any disruption in the gulf stream could cuase far worse problems then we have now. Not friction, but temp differences could completely change how the gulf stream flows, or if it flows as all.

You also say that these fix the problem caused by global warming. This one thing is going fix all of global warming? There is a lot of stuff contributing to global warming, if it is even true. This only changes the temps of the water, there are still greenhouse gases from fossil fuels and other carbon emmisions, you think these pipes can rewind all that?
