The problem with hydrogen-fuled cars

[Coelho]

I should have known some physicist would come along and save the day! :jointsmile: Much thanks for the help Coelho.

Youre welcome! :thumbsup:

EDIT: BTW, isn't Brazil the country that's converted 85% of it's car fuel to sugar-cane bio-diesel? How's that working out?

Yeah they burn 85% ethanol for 30 years. They don't have to import a single drop of oil. But it takes a shit load of sugar cane to power the country.

Well... i think 85% is a bit too much... but surely a large percentage of our cars are indeed fueled only by ethanol (alcohol), and the new cars, called "flex", can be fueled with either gasoline or alcohol.
Its have been working fine, as the alcohol is cheaper than gasoline (about US$ 3.80 / gal), and less poluent. Unfortunately, it indeed takes a lot of sugar cane... but at least its a thing that grows from the land and can never end, unlike the oil...
The research of alcohol fueled cars started at the 70s or 80s during one of the oil crisis, when the government needed an way to decrease the countries oil needs... and its nice to know that our technology, that is very sucesfull, could be exported to other countries.
