i’ve seen the other wave energy extraction devices and they don’t much impress me, i’ve seen a couple examples on GizMag. considering the vast amount of energy that the oceans possess the existant ones only scratch the surface of useable energy, if i could even call it scratching. This idea would not only capture wave energy, but also tidal energy. One problem i see right off the bat is it would restrict the surface module to one place, and in a storm, you would have to disconnect from the device so as not to break it. There are probably other issues too but this should be discussed more. it’s out there it seems but so is this whole friggin idea of seasteading, and that’s what’s so cool about it.
Essentially desalination is just turning seawater to steam, separating water vapors from salt, then letting the vapor cool into a separate place sounds simple… wouldn’t it be cheaper to just build something ourselves?
