I found a cool article on using the chemical differences between water with lots of ions in it (salt/seawater) and water with fewer ions (freshwater) to produce electricity over at the New Scientist. I’m not sure that this so called “blue power” is going to be a long-term solution to our energy needs, but it’s just really cool that scientists are doing such a good job of exploring new venues and creating new technology to make renewable energy a reality (in our future, at least). Every step along the way is incredibly valuable, even if its not the final or most efficient step. I do have complete confidence that we’ll be able to develop non-fossil fuel based energy in this generation, and that will be a huge boon to the environment, to American prosperity, and to global security.
