I have an idea on how to stop the oil leak in the gulf. I will say it and would welcome a response on why it would work or not work. My idea is to cool the contents of the pipe down to the point that it slows down. If it does not freeze thats ok, at least it would slow it down and make the other processes that have been used thus far more viable. My theory is to either pump or sink a tank of liquid nitrogen down to the bottom. If from the surface if you pumped liquid nitrogen through one main tube it might take more of a pump than if you used several small tubes to help overcome the pressure of the 5000 ft. depth. My idea on one side would be to introduce liquid nitrogen up stream in the pipe. Let it flow for a while and hopefully it would freeze the contents of the pipe, if not, since the temp. of the water at that depth is already 42 degrees, you possibly could freeze the water at the end of the pipe. I realize there is quite of bit of pressure at the end of the pipe, but maybe you could shroud a relatively large area at the end and introduce the liquid nitrogen to create a huge ice plug. I also did a small experiment today. It was vegetable oil not crude, however it it got solid enough that i think it would not flow through a pipe.
Thanks!
Just an idea!
