Solar Hydro Electric Dam

Run a tube from the ocean to a low lying desert, tap the hydro power resulting from the flowing water.
  [vote for,

Death Valley is 280 feet below sea level. You could run a tube several hundred miles from the ocean and tap the energy as the water dropped to the lower level. It would then be evaporated from the artificial lake by the temperatures that rise up to 120 degrees or more. It's also very dry there as well so the water would have no problem gassing out.

Not sure how much volume you could get replacing that evaporated water but it seems plausible.

       Hmmmm, collect energy from the moving water by all means, but could the water not be turned to steam before exiting the pipe? The expansion is where the real torque would be.   

       Hey, the faster you can get rid of the water the better, whatever works.   

       You could also use the resultant inland sea for recreation. Nothing much would be able to live in it due to the ever increasing salinity but you might be able to do something with it for fun.

       What do you do with the salt ?   

       "every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts "   

       35 kilos of salt per cubic metre of water.

       Yea, that's a lot of salt. Harvest it I guess. Put all the salt evaporators and salt mines out of business.   

       Worth it? Ahdunno.

       There was/is a serious plan to do something like this at the Dead Sea in Israel. See Two Seas link.

       I don't know, looks like they proposed using the energy to run a desalination plant and make a fresh water lake.   

       Mine's a little less ambitious, just move the water, tap it's power and evaporate it.
