A while ago a co-worker told me someone had harnessed nuclear fusion to make a welding machine that ran off water. I didn't believe him, of course, but the technology he was talking about was pretty freakin' cool nonetheless. Denny Klein worked on a process to turn water into a combustible gas, which I thought couldn't happen. I was wrong.
Hydrogen Technology Applications has a working welder that was showcased in this news clip. Take a look and let your jaw drop. It's ok. Here's the patent too.
We'll also have to see how well the water-powered Hummer goes over for the government. Hopefully this technology will help alleviate even a little dependence on oil. Wouldn't that be swell?
