Can you imagine if this engine is actually rolled out to the general public. How many countries wouldn't need to look to the middle east anymore for fuel? How poor would the Emirate states suddenly become when no one needs their oil anymore? In fact you can include the Yanks in that.
I give you, a water based engine. It is only 7 and a bit minutes long but, well worth the view.
