No worries, then! quote:Also a Hydroelectric dam on the strait of gebraltar would give yurope massive amounts of energy. So you somehow think you will get more energy out of a hydroelectric dam at the Strait of Gibraltar than you would spend pumping water out? Even ignoring the amount of energy and resources you'd need to put in just to install a dam over there, your idea violates conservation of energy. With luck you'd break even, except 2nd Law says you can't even do that.

LeoMarr posted:so draining the water a few hundred feet, then controlling the flow of water into the mediterranean from the ocean would somehow break the laws of physics? How much energy at a minimum do you think it would take to get the initial height differential? Answer: at least as much as the resulting height differential. The process loses you energy. You might as well just put that energy in a battery to use it later. quote:Even if we didnt slowly drain it a Dam that large would produce a massive amount of energy. Where is this energy coming from? quote:Aswell as the land up for sale and usage after we drain it. Thats a lot of fertile land up for usage and sale. How sure are you about that fertility? We're talking intense salinity to start with, and that's bad for most crops.

Venusian Weasel posted:You wouldn't even need to pump. The basin's dry enough that it loses more water through evaporation than rainfall fills it. The connection to the Atlantic through the Strait of Gibraltar is the only thing keeping it filled, and the entire basin has dried up almost completely several times in relatively recent geological history. The idea was in the original German plan was to dam the Strait of Gibraltar and Straits of Messina, then let evaporation do its work to lower the sea level. Once it dropped far enough, you'd be able to let enough water through turbines to fulfill energy needs without worrying about pumping it out again, since the basin is so large. The big problem with that is that it would take decades for the sub-basins to drain enough to actually do that. That seems to make a bit more sense, but honestly, if you're in effect trying to get at solar power, you're really much better off getting it through solar panels rather than cycles of evaporation and hydroelectric. quote:The bigger problems are managing the giant dust storms that will result from uncovering giant swaths of seabed, and then rehabilitating land and aquifers that have been saturated in saltwater for centuries. But I guess if you have the resources in place to build a 15km wide, 900 m tall dam, then that shouldn't be too big of a deal! It's not really worth the effort, because the amount of manpower put into it would be better used on other infrastructure projects. I feel like it might make sense to try and do some height control of the Med through dams or something at both Gibraltar and Suez because of rising sea-levels due to global warming, but you also have to take into account that you need to make sure that ships can travel through as well, further complicating things. Adding hydroelectric into the situation sounds like it would make things even more ridiculous.

President Kucinich posted:Where we're going we don't need oceanographers. Once all water has been dammed and displaced, you will be first into the salt mines. More like salt gathering. It's going to be on the surface of the erstwhile seabed, isn't it?
