If you want to go to technicalities, it gives out water which is a greenhouse gas as it absorbs photons in the infrared part of the electromagnetic spectrum. Nevermind the fact that hydrogen has to be produced from energy, at least in part, produced from fossil fuels. |

@ the news:
This just over-hyped non-sense. Until these things are being sold at dealerships, Honda isn't offering or producing squat. The cars themselves are being leased, and the price tag is apparently well over $200,000 though again, they aren't being sold so it's a moot point. These cars are only being leased in 2-3 cities near Honda-approved hydrogen stations. Wake me when there's a hydrogen economy for these things. ![]() |

No it isn't and yes it is, in that order. Hell, you can use home solar panels or wind generators to make your own hydrogen gas to fuel your non-existent hydrogen fuel-cell car right now. There's even a group claiming to have made a simple aluminum-based generator just recently, but it is vaporware until demonstrated otherwise. On the storage side, there have been improvements that don't require super-chilled solutions, but nothing is particularly ready for primetime in vehicles. If Honda and others are serious about offering hydrogen cars in the next decade or so, they'll get on the asses of the oil companies about fitting their gas station with hydrogen pumps nation-wide in preparation, none of this namby-pamby photo-op hubris or this "free market will decide" bullsh*t. The stations are already there, plenty of them can be remodeled to offer one pump for hydrogen gas and the others remain petrol. It will take years, but such preparations should be done and ready in many markets by the time hydrogen cars are available for purchase, instead of just select, meaningless markets that no one cares about. I mean really, they couldn't even go fully into LA, but rather an outlying area? Yeah, TOTALLY ready for primetime.

Yes, it emits water, but I somehow don't think that water is going to contaminate the atmosphere. It's my experience that water vapor condenses into clouds and falls down once there's a certain amount up there (one of the little secrets of life on Earth). I suppose it might make our cities unbearably muggy, but that's it. Of course it just passes on the pollution to whatever factory is manufacturing the hydrogen, unless we have a LOT of green power plants running. That was my point with the "tidal plants" remark (no, Snoopy, I'm not that clever). And I don't take anywhere near six seconds to read that short sentence in your sig. So ![]() ![]() ![]() |

Yes, but if the air can't hold infinite amounts of moisture, it's going to condense on its own on every nearby surface, right? Then it will evaporate, join the clouds, come down again, and so forth. No? I'm not entirely sure what you're asking. Normally, the idea is that a hydrogen fuel-cell car would emit water vapor as exhaust. Whatever happens to the water later doesn't really matter; it has emissions. I claimed that if you just store the water vapor until it condenses, [then presumably dispose of the liquid water in some controlled fashion, or reuse it in the cell], you won't have any emissions. Neither case really matters, because the real issue is that the problematic emissions (pollution, CO2) have been moved to the power plant, which probably burns coal. |

BHecause the last thing I want is more frigging rain thatyouverymuch. |
