Take one giant leap forward on the Sci-Fi becoming reality timeline. Two separate Japanese companies, Mitsubishi Chemical and Sumitomo Chemical, claim to have each invented a way to spray on or paint on OLEDs. This would mean being able to literally buy a "can of TV" and just paint it onto your wall, in theory. On top of that, these OLEDs would actually power themselves buy utilizing the solar panel properties of the chemistry. So, in theory again, no power needed. They also both claim being only 2 years out from a fully functional prototype system...

Ok, i have a stellar plan to end vehicle generated pollution within a few years. Make gasoline free. Yep, thats it. Nothing more complicated than that. Or at least make it silly cheap. WHA! you say? That makes no sense you retort?
