It's a hoax. As many have pointed out, it would be quite easy to prove that the thing works. Instead, there's only a single news media reporting about it, namely
www.baytoday.ca. Nobody else, except for the sites linking to it...
Not to mention that someone at MIT would have published something about it by now.
The inventor is even concerned about the money-making possibilities of "god light", the angel light, next generation thingy, and is thinking about selling it at eBay...
Yeah, right.
