I dated a guy about 6 or 7 years ago whose dad was a scientist & had developed a car that ran on water. He won all sorts of awards. I was so surprised, like yay, now there will be an alternative car! My then boyfriend said it wasn't such a big deal; similar technology had been available for years. He said that it's widely known in those circles that inventions like his dad's will never actually hit production, due to the government & its heavy involvement in oil. Sad.
