I ran across this and thought you might find it interesting. Blasting rust off metal using nothing but light.
Don't see that making it to public use anytime soon....
There would be thousands of one eyed people going to court..
That looks pretty cool, and a lot less mess than a sand blaster. :)
In another video, they show someone putting their hand in front of the beam, and it appears to do nothing at all to skin. So I assume it does not make the metal hot.
I saw a demonstration of the technology. It was amazing! Right now, the equipment is just too expensive for smaller businesses.
While that does look pretty cool - if you were to use that on a truck from the midwest, there'd be nothing left but the tires.
