Another Alternative - Propane

I wrote a blog not too long ago about Biodiesel, now it's propane's turn.

Normally when you think of propane, you think of gas grills and stoves, correct? Well, apparantly it can, and has been used as an alternative fuel source for cars. Of course, like any other alternative fuel source, it requires some serious, and sometimes pricey modifications to an engine.

When compared to normal gasoline, propane burns cleaner, as it gives off 18 percent less CO2, 20 percent less NOx, and up to 60 percent less CO.

However what is somewhat interesting is that you can expect about a 13 percent decrease in fuel economy. Meaning you have to use more propane (by volume) to get you the same distance that gasoline does. Despite that, it still expels less hydrocarbons by volume than your typical gasoline car.
