    After taking my kids to the playground, watching them play on the merry go round whilst holding a bottle of water and spilling it, and seeing the arc of the water as it released from the bottle, I started to consider if it would be possible to utilise the earth's rotation to pipe water from Antarctica. Not being a mathematician or a physicist I thought I would post here on this forum a mind experiment.


    Considering the sheer amount of energy contained within the earth's rotation, I am wondering could this be theoretically possible, If two things that make sense from the standpoint of the everyday i.e. Centrifugal force and thermal wicking, would be applicable in a macro project of this size.


    As stated, I really don't know the maths that should be applied, but have considered some hurdles that possibly may affect or completely stop this from working.


    Physical


    1, friction in the pipe.
    2, gravity variations along the line of arc.
    3, thermal bottlenecks.


    Economic


    4, excessive infrastructure maintenance.
    5, excessive cost.


    Geopolitical


    6, international jealousy.
    7, resource wars.


    Ecological


    8, environmental damage at melt point.
    9, change in hydrological patterns at evaporation point.


    I would be very interested to see your point of view, or a mathematical argument that either supports or debunks this theory.

    Ah you're sharing some thinking with Isaac Newton. What you might not know is the Earth is oblong, specifically because of the effect you're talking about.

    Have you noticed any net flow of water in the ocean from Antarctica toward the equator? If it's not flowing in the ocean, why would it flow in a pipe?

    Yes I'm aware of that. If taken to the extreme the earth would be saucer shaped.

    I was under the impression that both the atmosphere and the oceans displayed similar patterns with regard to the Coriolis effect. Wouldn't a containment of (or redirection) of that energy cause a flow from a high energy state to one lower? Also, It's a bit late for me ATM, so don't have time to find a reference, but I'm fairly sure there are significant currents coming off the Antarctic.Whether those currents are related to the rotation of the earth or density and temperature changes only I don't know. I'll come back to this in the morning. But as I said in my OP, it's only a mind experiment.
