Would this work

    I thought of this before but have just decided to ask the question if it would work after seeing some similar question asked.

    Its way of using water and gravity to get "free" energy.

    So basically you put a massive pipe down into the sea or any big hole with water in it. The pressure is greater the further down you go and the water in the pipe would also take some force to push up. But, if the pipe was wider at the bottom there would be more force coming up to the top so pushing more water up.

    There would be a number of ways to tap into that energy from placing an old fashioned water wheel to catch the falling water or putting some sort of turbine in the pipe that the moving water moves.

    Its probably already been thought of but I'm still curious about hearing if it would/has work. Cheers.

    No, it won't work. The forces exactly cancel out. Simply stick an inverted funnel in water. You'll see water doesn't come cascading out the top.

    Water + Gravity = HydroElectric power.

    Ah But,what if you seal the top and then pull it up out of the water, wont atmospheric pressure shove the water up to about 9-10 M giving you your required height for hydro electric

    I'll just have to work on my anti gravity device so! :D

    Yea guy, the width of the pipe has no bearing on the hydrostatic pressure.

    That is calculated using P = Rgh

    R (Rho) is the water density
    g is gravity
    h is the height of the column of water (i.e. depth)

    Oh I'm Very Anti Gravity meself

    No time for it at all

    Always bringin me down
