The real biofuel story: grass and algae good, corn bad

Big props to the person who pointed me to the How Green Are Biofuels? Comparison Chart

The chart was created jointly by faculty members from University of Washington and The Nature Conservancy and published in the Seattle P-I (see the article Bio-debatable: Food vs. fuel).

Most interesting is not just how horrible the rating of corn-based solutions, but also the fact that wood residue is listed whereas oil waste is not. I have a really hard time understanding why waste oil (e.g. cooking oil from all the restaurants) is never factored into these discussions, especially since a vast majority of biodiesel production systems in place today use exactly that source.

Anyway, here’s the full chart in all it’s beauty.

I am starting to dislike corn more and more every day. How in the world did America get so dominated by the corn industry? There must be a book on this somewhere.

Coke in every other country in the world has sugar, but not in America…here we have to imbibe the disgusting corn syrup. So perhaps fuel will go the same way? While the rest of the world will develop sensible and safe ingredients for power (engines and bodies), the US corn industry will continue to monopolize and distort the discussion at home.

Real biofuel sources are not a trade-off with food. End of story.

Diesel is cool; too cool to be hot

A story called Diesel misconceptions is deceptively extolling the virtues of diesel. Negative marketing?

Consider the following analysis, for example:

Diesel engines power half the passenger vehicles sold in Europe but almost none here. Stricter U.S. clean air regulations have meant that – until recently – they were simply too dirty to be sold in the most populous U.S. states, including California, New York and New Jersey. This virtual shut-out means that American drivers have little experience with modern diesel engines.

First of all, nearly all heavy machinery and trucks on the road today are diesel. Experience with modern diesel engines? I think they could break down the numbers a bit more transparently. Many people in America have experience with diesel engines, but what they don’t have is any sexy marketing or CNN articles telling them diesel is one of the top ten choices they should be making.

Second, the reason they have been “dirty” is because unlike the gasoline counterparts that were heavily regulated and forced to clean up their act in the 1980s, diesel technology was ignored. This makes the “until recently” comment ironic. There was no regulation until recently that classified diesel emissions as too dirty for the most populous states. And, back to my first point, it should be obvious why the populous states led this controversial campaign.

This article does what it can to pretend to explain the current status and facts of diesel, but I think there is a more obvious reason that Americans do not think about diesel as their next technology of choice. Consider the following two articles on the same CNN site:

Six cars to survive the fuel crisis: These days, you no longer have to choose between saving gas money and getting the ultimate in car safety. more

The 8 most fuel-efficient cars These cars will squeeze the most miles out of your fuel dollar. more

Neither story includes a single diesel vehicle.

Lame.

Why is that? The diesel cars qualify easily. And I am not even talking about the next generation of technology about to reach the US. I’m talking about diesel engines from 2005.

Page one of the second story has a Honda that gets “28 miles per gallon-equivalent of compressed natural gas”. Who would want that instead of a diesel that easily gets more than 30mpg. Strange, eh?

And then there is the Chevy Tahoe example in the first story: “What’s a full-sized SUV doing here? For starters, it’s a full-sized SUV that gets the same city fuel economy as a four-cylinder Toyota Camry.”

Yeah, 21mpg is a pig no matter how you slice it and it does not belong in the line-up. What’s the excuse?

But there are things the Tahoe can do that a mid-sized sedan just can’t. Besides being just plain bigger and roomier than a car, the Tahoe retains the full towing capacity of the non-hybrid version.

Let’s see the numbers, shall we? If mpg is an issue, combined with towing power, than diesel options make all the more sense to include.

Apparently CNN marketing/editors hate diesel. Strange.

The good news is that, if the Internet is any guide, the more dynamic market option (diesel) may prevail over the centrally planned ones (hybrid/battery, hydrogen, natural gas). While people could respond today to a survey that hydrogen is cool, because big sexy concepts are easy to see (like describing mountains instead of grass), the state of things could always change overnight when the time and money savings possible from a small diesel investment become clear due to the numbers.
