While nanoparticles and nanocrystals have always existed -- they're even found in volcanic ash -- it was only recently that scientists could manipulate things on the nanoscale. What applications might nanotechnology have in fuel efficiency?
Imagine how convenient it would be if two-thirds of the Earth's surface was covered with a readily available, nonpolluting fuel source. With the discoveries being made in regards to salt water fuel, you may not have to imagine much longer. In 2003, John Kanzius serendipitously discovered a way to burn salt water. How would salt water fuel impact the world?
