Re: salt water instead of gas?
[ QUOTE ]
the way i interpreted it is it uses a little energy to get the initial burn but then can get a [censored] load of energy from the salt water. Kind of like how to start a fire you strike a match or use a lighter but still get a ton of energy from whatever you're burning.

Ok, we disagree. How can we ever settle such a disagreement? I'm willing to bet $1,000 against $100 that your interpretation is wrong. Do you want to put your money where your mouth is, even given 10:1 odds? I thought not.
This isn't the first story on using an external energy source to split water to get hydrogen and oxygen, which can then burn to produce water. The reporters cut the "uninteresting" statements by the engineers about how you don't get more energy out than what you put in.
The reason this isn't completely uninteresting is that you don't have to have the energy source at the same location as the receiver. You can have a transmitter some distance away. On a good day, maybe you can get 50% efficient transmission, but that's going to be tough in a car, and you would still have to deal with a heavy, inefficient internal combustion engine afterwards.
