I actually don't think this is an effective way to drive cars, but it actually depends on the amount of energy which that wave generator requires, and how much energy it is produced by burning that salt water. In other words, some data about the efficiency of the whole apparatus, should be mentioned!

Here's a classic example of what can happen when an airplane tries to refuel in the air. Pretty dangerous stuff!
