It's not as simple as all of that... These things take time... Not because of technology, but because of economy.
Lets say we start using all electric cars tomorrow. What about the guys who work at the oil refineries, and their families? What about the gas
station owners? And the numerous other industries supported? What do you do when they are all unemployed and looking for work? There are MANY
implications here, and a simple answer won't do...sadly.


If you can imagine it, tell people, and it will come true. There
are solutions out there, the problem is the person that came up with them, thinks nothing of them. See "A Beautiful Mind " starring Russel Crowe.
