Green Options

In what could be a major breakthrough, Joule Biotechnologies announced that it has directly produced fuel from the plentiful carbon dioxide in the air around us using highly engineered photosynthetic microbes.

As part of a National Science Foundation grant program to examine cutting edge ways to make nature work for us, a team of scientists at Iowa State University have been awarded $2 million to unravel how some plants and algae can make hydrocarbons and discover if the genes that govern that process might be isolated.

“These plants are capturing solar energy and creating something that’s chemically identical to petroleum,” said Jackie Shanks, Iowa State’s Manley R. Hoppe Professor of Chemical Engineering, in a statement.

Just about this time last year I reported on the very promising and innovative Mcgyan® biodiesel process. It was one of the most popular stories gas 2.0 ran that year, and rightly so: the breakthrough seemed to deliver the possibility of making biodiesel in mere seconds from start to finish, reducing costs by half the price of other biodiesel, producing no waste, using no chemical reactants, and using any animal fat or vegetable oil as a feedstock.

At the time the company in charge of the project, Ever Cat fuels, had only succeeded at making a small-scale pilot operation of 50,000 gallons per year. But, as of 2 days ago, the process has been completely commercialized.

I’ve been happy with all the recent efforts by European auto manufacturers to bring fuel-efficient diesels back to the States. From Volkswagen to Mercedes, diesels seem to be the new attempt at pleasing the US “green” crowd with classy, low-emissions fuel-sippers.

Reading that last sentence over, it seems funny to call them a “new attempt” because these high mileage diesels have been available to Europeans for a LONG time — but that’s another story.

So, while it’s debatable whether a gasoline-powered Prius at 40 mpg is more “green” than a diesel-powered Jetta at 40 mpg — it all has to do with how much of each type of fuel comes out of one barrel of oil — It’s a fact that having these new clean diesels as an option is certainly something the US has been lacking for a long time. And I appreciate having that option, I really do.

This one may offend you more sensitive types as “ironic” or not green at all. But the fact is, the world needs bulldozers. Lots of them. But until now, anyone seeking a hybrid bulldozer was out of luck. But Caterpillar, the prolific maker of construction equipment has announced that for 2010 they will be selling the D7E, a diesel-electric bulldozer.

This is actually old news that recently resurfaced, and as a lifelong Cougar aficionado I can’t pass it up. In actuality, the Mercury Cougar was a refined, “gentleman’s muscle car” based on the 1st generation Mustang. It came standard with a number of gas-guzzling V8 motors including the epic “Boss” 302.

But the pristine-looking 1967 Cougar pictured here has done away with those gas hogs in favor of a Mercedes turbodiesel motor that runs on, you guessed it, biodiesel.

In the U.S., gasoline and diesel are dirt cheap compared to their cost in Europe. In late August, the average U.S. price for a gallon of gas was $2.60, and a gallon of diesel cost $2.65. Both diesel and gasoline come from the same barrel of oil—since diesel is a heavier, less refined product, it has historically cost less than gasoline. However, the relative price difference in the U.S. is determined by market forces, refinery constraints and taxes. Typically, demand for gasoline is higher, and U.S. fuel taxes favor gasoline, making gas less expensive here. Federally, we tax diesel at a higher rate than we do gas—24.4 cents per gallon of diesel versus 18.4 for gas. Some states tax gas a higher rate, but on average, the diesel tax is higher (With state taxes added in, the average diesel tax is 51.4 cents per gallon, gas is 47.0). According to the Energy Information Administration, since 2004, diesel has generally cost more than gasoline in the U.S., year-round.

What you see above (center) is one of the most well-engineered “Franken-cars” of all time: a factory-modified 1980’s era Mercedes-Benz 190 diesel, stuffed with the company’s latest BlueEFFICIENCY CDI engine, which makes more than double the horsepower and nearly three times the torque of the original 1988 D.

How far we’ve come in 20 years!

It’s an Audi-tastic day! Johan de Nysschen, President of Audi US, certainly took some major heat over the interwebs today for his inflammatory and derogatory statements that the Chevy Volt is a “car for idiots” and that electric cars are only for intellectual elites to “make a statement.” They were especially curious comments because they came at the same time that Audi launched a website touting the power of electricity.

So, knowing how these things usually go, after some serious damage control conference calls between the Audi communications folks and higher level management, de Nysschen was probably forced to respond with a much more diplomatic take on his positions — what he should have done in the first place. It’s so hard to backpedal once you’ve said something as concrete as “you’re an idiot if you buy this car.”

Bring on the war of words. In a frank conversation with MSN writer Lawrence Ulrich, Audi of America President Johan de Nysschen has said that the Chevy Volt will fail and that anybody who buys the car is an idiot. Not only that, de Nysschen has lumped proponents of any type of electric car into a category of “intellectual elite who want to show what enlightened souls they are.”

I’m guessing that means a fair amount of the people reading this would be considered idiots and pompous intellectual elites in Mr. de Nysschen’s book. Funny that. Hearing an Audi executive mocking any other car as being for intellectual pompous elites is, err, interesting, given that Audi is known for being in exactly that category themselves. Agh.

At the upcoming Frankfurt Auto Show (September 17-27, 2009) Volkswagen will be debuting updated versions of its Euro-spec Polo, Golf and Passat diesels. According to European testing methods, the Polo BlueMotion will get the equivalent of 71.3 mpg (US), the Golf BlueMotion 61.9 mpg, and the Passat BlueMotion 53.4 mpg.
