I apologize if this is in the wrong place or so stupid that it shouldn’t be posted, but the idea will distract me for weeks if I don’t get input on it.
I’ve been working on a concept to combat two problems: rising sea levels and increased average air temperatures. Basically it revolves around that ridiculous episode of Futurama where it’s shown that they combat global warming by dropping a gigantic ice cube in the ocean periodically. This got me thinking, why not?
So the expensive foundations of this system would be plentiful renewable energy sources (solar, tidal, and wind primarily), a desalinization facility, and a series of huge refrigeration units.
The sun shines, the tide goes up and down, and the wind blows. This energy is then used to distill salt water into relatively clean fresh water (because salt water freezes at a lower temperature). Then the fresh water is frozen by large compression refrigeration units. The heat removed in the ice making process could be recaptured in the desalinization process to make it more efficient. The end result would be giant ice cubes floating away into the ocean as well as a large amount of salt removed from the water (which could be sold to help pay operating expenses).
Obviously it would be cost prohibitive but I see it as a possible alternative to losing large amounts of coastal land to rising oceans.
Am I a crack pot or is this a workable solution?
