The Cost of Energy, Free and Otherwise
Popular Mechanics has an article comparing alternative fuels this month. They did a real, hands-on test driving cars coast to coast on gasoline, ethanol, methanol, biodiesal, compressed natural gas, electricity, and hydrogen fuel cell. Gasoline did better than you may think — it hovered in the middle of the pack at 33 mpg while electricity blew away the competition at 202 mpg.
It’s not a perfect comparison since they had to use different cars for each fuel, but it’s about as close you can get to seeing how these alternatives fare in the real world.
Surprisingly, PM didn’t test a car run on water, which I actually saw in the news a few weeks ago. Guess what station? They report, you decide whether they’re lying or confused (I’m guessing the latter in this case, since it’s an affiliate and not the evil empire’s home base.)
Once you’re finished laughing at the above linked video, head on over to see what James Randi has to say about that load of crap.
