Why don't we just pipe our water all the way out to the sun and pipe the steam back to earth.
I'm curious if it would even be thermodynamically possible. If we could magically run a pipe that far, would the heat from the water radiate into space before it reached earth to do anything useful?
Someone get XKCD to do a video short on this.
i imagine filling any decent sized pipes (! plural because heat exchange has to loop) to 1au would use most of the water on earth.
