Green Options

A group of scientists from both the public and private arenas has announced that they’ve successfully engineered a microbe that contains all the bits required to turn raw plant matter directly into diesel without any refinement or intermediary steps required.

The microbe is a modified strain of E. coli (that’s right, the same type of bugger that’s responsible for some nasty gut infections) that has been enhanced to produce tailor-made diesel molecules, alcohols and waxes directly from hemicellulose—one of the main components of plants. Not only can the microbial products be used for fuel, but the team is also setting their sights on directly producing environmentally-friendly—and industrially-necessary—surfactants, solvents and lubricants.

We’ve talked a lot about electric motorcycles here at Gas 2.0. But what about biodiesel? Once the darling of many eco-modders, the fuel has largely fallen out of favor. But not with everyone.

Meet the Metalback motorcycle concept. Designed by Jordan Meadows, a man with plenty of street cred when it comes to vehicular design. The Metalback concept combines alternative fuels and recycled materials in a missle-shaped machine drawn straight from some science fiction dystopian future. And it just plain old looks cool.

Volkswagen has announced that the documentary “Racing Under Green”—detailing the trials and tribulations of the Jetta TDI Cup, the U.S.’ only professional green racing series—will premiere the week of January 18 on the various channels of Discovery Networks, including Planet Green, Discovery Channel, and The Science Channel.

In addition to following the stories of last season’s 25 drivers, the hour long documentary will examine some of the “green” aspects of the Jetta TDI Cup, including the use of biodiesel blends and the support of carbonfund.org.

Not everyone wants to save the planet. This is a sad, but true fact. Yet everyone who lives and works within a capitalist economy loves saving money. So it’s good for the planet that, in many cases, saving money and green initiatives go hand in hand by providing an increased economic benefit while lessening environmental impact. Many of these benefits come directly from the government, such as tax exemption status or tax credits for using alternative fuels in vehicles.

And as the German biofuel industry is showing us, taking away those economic benefits can lead to the utter collapse of what looked like a maturing faucet of biofuel.

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 I’ve said before, SEMA is not usually a place you expect to see lots of alternative fuel vehicles. But in recent years there has been a paradigm shift, and increasing floor space has been devoted to debuting technologies and cars that conserve gas, rather than waste it.

Factory Five, out of Wareham Massachusetts, is a well-known maker of kit cars based on classic Shelby designs including the Cobra and Daytona. Amp=D has taken one of their kit cars based on the iconic ‘33 Ford and built a powerful electric drivetrain around this handsome hot rod.

A group of University of Kansas students have rigged up a 1974 Volkswagen Super Beetle to run on a mix of biodiesel and battery power.

The team, calling themselves the Ecohawks, claim the quirky hybrid is capable of getting 50 MPG from a series of 10 lead-acid batteries and a biodiesel generator.

Performance-wise, although quite cool looking in a retro kind of way, the car isn’t exactly what you’d call a speedster, topping out as it does at a leisurely 30 mph.

That doesn’t seem to bother team-leader Prof. Chris Depcik though, who told reporters, “We have driven it around and reached approximately 30 mph, but this was more of a proof-of-concept drive without pushing the boundaries. We are currently getting the vehicle into road-ready shape to be driven safely in order to determine these values.” (More pics after the jump).

The concept is good - a completely sustainable Formula 3 race car. But the products used, well, that may be another story. The race car is made from woven flax and carrot pulp as well as recycled carbon fibre and recycled resin. In addition it uses biodiesel made from chocolate and animal fats and is lubricated with plant oils. Hungry anyone?

According to EPSRC funded researcher Dr. Kerry Kirwan with the University of Warwick, the car is not just environmentally friendly, but also fast boasting a top speed of 135 mph and can go 0-60 mph in 2.5 seconds. Oh, and did I mention it’s turbo charged to give it more torque?

Students from West Philadelphia High School have built a diesel-hybrid race car that goes from 0-60 in four seconds. While the car currently gets 60+ mpg, they hope to soon break 100 mpg.

Why? They are competing for $10 million in the Automotive X-Prize .

Called the Hybrid Attack, the car was built by kids from West Philly’s Academy of Automotive and Mechanical Engineering. And if that alone doesn’t make them cool, they are the only high school team competing out of 90 different teams from the U.S. and overseas.

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.

With the attention on first generation corn ethanol fading, the next big thing on the sustainable fuel horizon is nonfood biofuel crops. Within that category, inedible weeds are taking a front-row seat due to their relatively low demands on water, pesticides, and herbicides, and their reduced need for tilling and other mechanized soil prep. Some weeds with biofuel potential can also thrive on contaminated soils, absorbing and cleaning pollutants in a process called phytoremediation.
