A scientist in the US claims to have found a way to burn saltwater. If true, this would clearly be among the most disruptive technologies ever to be invented/ discovered, leading to a complete recalculation of the energy-economics underpinning oil-based economies.
But of course, we've seen wild claims like this before, with cold fusion coming to mind. Extreme claims need extreme proof. While a number of questions immediately pop into my head (like how efficient the process is, how much energy input is required for a given unit of output, what happens to the leftover stuff in the water, etc.), I'm hopeful this particular wild claim has some basis in truth.
Time will tell.
