    Europe consists of a bunch of peninsulas surrounded by ocean.

    Water volume: 21,700 km³ (1.76×1010 acre⋅ft)

    https://en.wikipedia.org/wiki/Mediterranean_Ocean

    Water volume: 3,750,000 km³ (900,000 cu mi)

    https://en.wikipedia.org/wiki/Atlantic_Ocean

    Water volume: 310,410,900 km³ (74,471,500 cu mi)

    EDIT: For bonus points, if one is going to expend the waste heat on evaporating seawater anyway:

      The temperatures needed to boil water are not the temperatures at which to run datacenters.

        You don’t need to hit boiling levels to evaporate water.

          Any increase in temperature, which benefits evaporation, decreases the efficiency of running the data center.

          This is the vapor pressure curve for water. Under constant pressure and saturation of the air, the evaporation rate as a function of temperature is proportional to the vapor pressure curve. As you can see it is an exponential relationship.

          Now you have to offset that with the energy it takes to pump the water around, the increased costs for equipment that can deal with salt water, the increased costs to deal with flooding risks…

          You know what you could do instead?

          All it takes is a flat basin and a dam with a gate to let in water and then block it away. The sun will do the rest.
