Mr Warthog ,you dismiss new technology and ideas without researching them yet you assume that electric powered vehicles will prove our saviour .
I work in the power industry and in N America it is struggling to keep pace with increasing demand.
GW Bush when he was in office gave the green light to ,I believe , over 100 new coal fired power stations ,and they are also building new nuclear stations .
Canada and the US will also be flooding MORE river valleys to produce MORE electricity .
If you factor in a further huge demand because of a switch to electric powered vehicles ,even more power plants will have to be constructed .

Arable land will continue to produce either fuel or food depending on the economics .Poorer countries will continue to go hungry ,the market economy has no heart .There have been several studies done on the likely fuel production one could achieve ,they have been contradictory because some of them have been influenced by the petroleum producers .

The earth's core contains the means for power production if the resources are handled correctly and we develop the technology to exploit it .

Neither of us know what will eventually happen .There is technology out there that could revolutionise transportation but it will probably be stifled by Big Oil or the Car Manufacturers who manipulate governments .Joe public is a pawn and usually thinks what he is conditioned to think .

The next step in technology will have to concern power storage ,because without the means of storing a substantial amount of charge [ie batteries] electric vehicles will always have a limited application.However knowing about the need for better batteries and having them available is another matter maybe technology will advance and maybe it won't .It hasn't advanced much in the last century .

Don't forget the petroleum industry has the world by the nuts and if it can use bacteria to produce useable hydrocarbons ,then it will and you will not see rapid advancements in alternative fuels.

Electricmotor cycles may become viable ,there are several on the market now ,but I hope that petroleum powered bikes will be around for a long time .The soulless whine of an electric motor is no substitute for a barking megaphone .
