Any high school science teacher is familiar with a
battery science project. Two different types of metal in
saline electrolyte and what do you get... electricity. Oh,
and of course ah... saline metal hydride sludge and
chlorine gas. The gas can be harvested and sold for
use. The sludge, depending on the type of
metal used can undergo further chemical reactions
(possibly generating more electricity) to be turned into
other commercially viable chemicals and drinking water.
Since we have a nearly limitless supply of salt water (ok
they said that about oil and coal and trees and ...) in the
ocean plop a few thousand of these plants along the
coastline. TaDa! Cheap electricity and water supply for
generations to come... but not the generations after
||Isn't the metal eaten away?
||Where does the limitless supply of metal come from?
||damn science teachers need to do their jobs better.
||If you're looking for scientifically sound ideas aren't you on
the wrong website? It seems that most of the highest voted
ideas on this site were voted up for their absurdity rather
than their plausibilty.
