This is going around AGAIN? I was hoping it was debunked the first time but I guess I hope for too much. The problem is this part.
The discovery has scientists excited by the prospect of using salt water, the most abundant resource on earth, as a fuel.

A large amount of electrical energy is used to electrolyze water. That's not fuel, it's a naff form of energy conversion. Better off using old fashioned electrolysis.

What we really have is a form of electrolysis without electrodes. Might work as part of a treatment for cancer. Neat.

Don't these journalists know anyone who stayed awake during chemistry classes?
