Japan has developed a water-powered test car!! 
It can sustain 80 km/h for an hour on 1 liter of freakin’ water!!! How come we don’t have that already?! I will tell you why… it’s because of those money and life sucking oil companies!! That’s why!! 
All those oil companies better get on the right gear ’cause I’m not paying freakin’ $5/gallon!!
Also, the Japanese are super-smart and efficient. Americans? Blaaaahhhh…
Yes… but they also tend to be a bit…. too anal about things. Efficiency isn’t everything…
Almost all ways of creating energy that I know of consists of breaking more unstable chemical bond that results in a more stable chemical bond and released energy….
I dont know…I would not be surprised if this is some hoax to get some funding – the report was very sparse in the science behind it:

anyway, oil companies are not your enemies.
note: around when did gas prices start spiking from about mid to low 2 dollars a gallon to 4 dollars plus?
Viktor Schauberger did a lot with “water devices” in the 1940′s that would run without ceasing, after an initial start. It looks like most of his designs were based on generating a vortex that would develop a vacuum somewhere in the device. And the vacuum would keep it running. Also he pulled power from the vortex to turn a small gear that would be used to run a generator (for electricity).
I do not know who that Viktor guy is, but just by what you stated, if that vortex was truly a closed system (ie, no other external sources of energy kept the vortex going), then it sounds like a perpetual motion machine and thus violates the law of conservation of energy – ie, it generates more energy than it consumes.
In other words, I am skeptical of it.
