Inventor John Kanzius claims that he has discovered a way to make saltwater burn. This discovery could eventually lead, he suggests, to cars that run on saltwater. This suggestion places Kanzius in a long tradition of inventors (and con artists) who have claimed to have found ways to use water as fuel, reducing his credibility right away. But as always with these things, once is tempted to think that maybe this time the guy is really onto something.
Check out the video about his discovery on YouTube (below). Kanzius explains that he was originally searching for a way to cure cancer. He reasoned that if he injected tiny amounts of metal, such as gold, into cancer patients, that these metal bits would be attracted to the cancer cells, and he could then use radio waves to heat up the metal and destroy the cancer cells.
Fortuitously, Kanzius then discovered that these same radio waves would also heat saltwater and make it burn. He has yet to reveal the exact mechanism of his radio transmitter, but he has demonstrated the process.
Assuming the guy isn't totally lying (which is not necessarily a good assumption), then it would appear on the surface that Kanzius has discovered an interesting new phenomenon. But whether this phenomenon can be used to power vehicles is another question altogether. For instance, how much power is the radio transmitter using to ignite the saltwater? Somehow inventions like this always seem great at first, but they never seem to amount to anything.
