Hydrogen fuel, etc...

Due to recent japanese patented inventions - in 2018 cars with plain water- or gas- based hydrogen fuel cells will be mostly in use, i think. So on - gas stations ad's must picture not gasoline prices, but water and hydrogen instead... after that - the fighterplanes already can be unmanned bots, as many other things like city public transport... then USA can be already merged with both Canada and Mexica, forming the USONA - United States Of North America... with the money name of "amero" for example...
