The problem with hydrogen-fuled cars

[bhouncy]

I used to be a major proponent on hydrogen-fuel techologies, and I kinda sorta still am. Hydrogen is an immensely powerful fuel source, it doesn't waste other essential resources like food (as with bio-fuel), and there's been some ingenious methods that have arrived lately, allowing us to extract the hydrogen energy at a considerably lower cost/energy output.


Here's the problem though: hydrogen fuel proponents brag that the only emmisions are water coming out the tailpipe. The way I see it, that's going to be majorly problematic in cold areas of the world (IE my homeland, Canada). Imagine a bunch of cars all lined up in rush-hour traffic. It's 10 below, the cars are inching alone the road for half an hour or so, all dripping out water from their exhausts. That water is going to fall all over the road and create black ice, rendering the whole road slippery and undriveable. Am I wrong?

Sounds like you might be right.

I don't know how much water is produced but maybe it could be used to add to the water that is used for cleaning the windscreen. But then you would need more anti freeze so maybe some contraption to add both?

Or maybe add anti freeze to the exhaust. But I guess that would cause more pollution.
