oh, I can't rank all these. All I know is that I'd want hydrogen fuel cell technology to be #1, for selfish reasons. But it seems like biodeisel is moving forward pretty fast. |

Most of these suck for one reason or another.
Compressed air, hydrogen, and H2O all require electricity off the grid or some other source. I don't think which one matters all that much. It wouldn't have been as bad if the electricity actually came from solar or wind power. Very confusing survey since these options overlap. Why put electricity as on option if you are going to use electricity to make these other sources.
Ethanol is eating up resources that might be used as fertilizer, thus competing with our food source, not to mention most of our food production is created actually using fossil fuel. In other words, it would still be fossil fuels only in a different form. I guess bio-disesel is ok.
To be honest I don't really care too much about carbon emition and global warming. I am more concerned about all the other crap that comes out of gas refining. |

Something inexpensive.....I know nothing of the alternative fuels. |

Sorry this is a bit too difficult for me. I don't know enough about alternatives fuels apparently. |

I'd put fuel-cell in preference to internal combustion. And for fuels I like bio-diesel first followed by ethanol or butanol. The bio-diesel should be derived from algae, not food crops, or possibly by thermal depolymerization of waste. Likewise, the ethanol or butanol should be made from cellulosic feedstock rather than food.
Electric vehicles with batteries is interesting only if we construct alternative fuel electric power plants. For the moment, this means more nuclear power plants. Large solar thermal plants are a possibility in a few areas and solar power satellites are a possible option in the future.
Diesel/compressed-air hybrids are an interesting idea for certain applications, like what UPS is looking into for their delivery trucks. |

Oh, I forgot coal. Coal liquifaction is a viable alternative for making fuel that we can use now. The story was that it was not competitive with crude oil while crude was below $35/barrel. It's time. Yeah, it's still coal with all the problems therein but it's a lot better than burning coal in an electrical power plant, shipping the electrical energy over power lines with huge losses, and using the result to charge up banks of lead-acid batteries in cars.
I'd like to see large-scale development of bio-diesel from algae, cellulosic ethanol (or butanol if people could figure it out), and coal liquifaction all go forward simultaneously. The expectation would be that coal liquifaction would came online in large scale first (should have finished the plant back in the 80's and it should be online now, shutting down that project was a major mistake), to hold us over while the others are figured out. |

But I'm not opinionated on the subject or anything. |

I have no idea which one is best. I know nothing about vehicles or their fuel. |

I predict hydrogen Fuel-cell, will win this popularity contest, but I'd like to see Alcohol Fuel-cell car technology developed and used by all the most. The one I want to own most though is MDI's compressed-air Family CAT car. I can't wait until it becomes available. |

I don't know I don't pay much attention to that sort of thing. |

Other: I want to see pee-mobiles. I would like to have a car that runs on pee. There would never be a shortage and it's renewable ad infinitum. |

It could actually work in two ways; would you want that as a battery solution or have fractionated to be an internal combustion propellant (using a Pulse Width Modulator in it's electrolysis)? |

Whatever is cheaper and easier.

Something affordable that actually works, uses a renewable resource, and reduces dependency on nonrenewable energy sources. |

I would have to say none of these for me at all and no way, up here in the mountains they would suck
real hard and bad and probably fall apart on the highway |

A car that runs on human waste |

Battery solution is cheaper and easier to set up, urine electrolysis for internal combustion will give you better economy. |

With which? |
| CarolL | | (reply to docgbrown) posted 8-Jun-2007 3:21am |
Cheap and fast. That's how I like my coffee, my men and my fuel! |

| CarolL | | (reply to docgbrown) posted 8-Jun-2007 3:54am |
uh, thanks. What can I say except that I want my coffe, my men and my fuel easily available. I can provide the pee, but I don't know enough to make a choice as presented. I'm going to pull a paris hilton, and say if it works, it's "hot". |

pee just like hydrogen hmm... smelly

The only two I find interesting are the renewable diesel from animal fat and the Ethanol. Most of the others requires mining of the Earth and/or can be dangerous. But I know little about how they are produced. |
