I read this article about a year ago. its really really cool. I'm glad you posted it here. There is plenty of salt water... the oceans are getting saltier and saltier because of all the minerals sliding in from the rivers. I remember people telling me that the salt levels in our body was the salt level of the ocean when animals began crawling onto land. Sodium is so abundant... we just have to wait for them to figure out how to fit a device that does it into cars in great numbers.
All artists are obssesive compulsive... its what keeps us going!
The science inspires the dream, the dream creates the art...the art fuels the dream and continues to inspire the science!
