New Rechargeable Battery Uses Water 179
fergus07 writes "Scientists at Stanford have developed a battery that uses nanotechnology to create electricity from the difference in salt content between fresh water and sea water. The researchers hope to use the technology to create power plants where fresh-water rivers flow into the ocean. The new 'mixing entropy' battery alternately immerses its electrodes in river water and sea water to produce the electrical power."

Wow, two fallacies in one!
A sweeping generalization AND a stunning ignorance of the hydrologic cycle.
Well done good sir, well done *slow clap*

After the battery is discharged, the salt water is drained and fresh water is added to begin the cycle again.
This is awesome, we can use up all our fresh water and would have an unlimited supply of salt water!

You do know that there is an amazingly simple way to separate the salt from the water, right? It is called evaporation.
The concepts of desalination are certainly quite simple, its the economics that are complicated.
