A study showed a scientist found a way to have salt water (very abundant!) turn into a source to make energy. Currently they are trying to get financial fundings from the government to try to see if they can make enough energy enough to power a big rig. If they can get that big rig up and moving at regular speed, we might have found of alternate source for gas!! That is, if some company/organization doesn't interrupt and try to out buy the secret or something.. But wouldn't it be nice to run on something cheaper AND better for the environment?!
