There is an auto industry consortium sponsored Hydrogen fuel cell development center on the Sacramento side of the Yolo causeway between Davis, CA and Sacramento, CA.
The other day I found myself following a Mercedes Hydrogen Fuel Cell powered vehicle, a B-class I think.
I noticed something that got me thinking.
The exhaust pipe looked like a kettle of boiling water was in the boot of the car. Lot's of steam and a steady trail of water coming out of the tailpipe. Enough that it left a streak on the ground behind the car at 75mph.
What would a freeway full of these things do to the microclimate of the road? Enough water to keep it slick? Horrible ground fog when ever the pavement was cool enough? Oppressive humidity near any freeway?
Just my imagination? Or can someone with a periodic table and a slide rule riddle me this....
How much more water per mile is dumped out of the tailpipe of an H2 burner (at the industry quoted 15 pounds of H2 per 300 miles) versus a good old-fashioned C8H18 burner?
Nothing but pure, clean, drinkable water out the tailpipe? Yeah, well water rusts steel, drowns people and ruins picnics. The vapor could encircle the globe and -GASP- cause a greenhouse effect.
Not to mention the nukes required to generate the stuff. LOL.
I am waiting until the cost of H2 vehicles dips down below $300,000 before I will think of picking one up.
