Replying to Licuid nitrogen+SNOW=HEAVEN

I saw a video of them setting up icer and they had a put down something before hand i thought. Now i started thinking and drafting out what would be a system to release Liquid Nitrogen (N). Liquid N is less desne than water, or snow.

IIf I lay out a pipe with fifteen valves for a 15 foot track of snow, On elevated land. And we put borders up. Fill that up with water and put Liquid N as a feed in the pipes. Wait for the pipes to freeze then put ice on top of the water. Let the ice warm up, then break it up then. Release more Liquid N as need to keep it cooled. You need the pipes to be frozen other wise it will explode. Nitrogen will expand when warmed. The density of Nitrogen Changes from liquid to gas. The frozen pipes forces Liquid N to flow in one direction and it will be controled with out any harm to our selves. We could harness energy this way too. Think of it We compress the Nitrogen as it goes to gas then make turbines and blow it out.

So mayn posibilites and i know for sure i lost all of you.
