How reliable are alternative fuel cars?
methanol is undergoing a reconsideration by many as an effective means of producing other alternative fuels2 . it plays a significant role in the production of biodiesel, an emerging alternative fuel that has been generating a lot of excitement. Furthermore, current research suggests it may be effective as a fuel source for hydrogen in fuel cell vehicles, and methanol derived from natural gas is used to manufacture Dimethyl either (DME), another emerging alternative fuel. http://www.futurecars.com/futurefuels/methanol.
Depends what you mean by alternative fuels or otherwise known as clean fuel. The most reliable and perhaps better than gasoline powered is electric. There is also hydrogen fuel cell cars and air cars. Here is a good clean fuel resource: http://www.futurecars.com/articles/clean-fuel.
