Vitruvian Energy crowdfunding to make EEB, a trashy biofuel

When sewage is treated at a wastewater treatment facility, biosolids are the byproduct. After being separated from the water, biosolids are usually sent to a landfill or incinerated. That doesn't mean that they're without value, however. Vitruvian Energy has created a process to make a usable fuel out of this human waste product, and while the source is pretty gross, it is undeniably abundant, and the results are much cleaner. EEB can be made for less than $4 a gallon. In a process that Vitruvian Energy claims is energy efficient, biosolids are femented and introduced to a type of bacteria to create PHA plastic. Reacting the PHA with ethanol creates the ethyl-3-ethoxybutyrate (EEB) biofuel. Vitruvian says EEB can be blended up to 20 percent with gasoline or diesel without any engine modifications. This lowers the carbon footprint of the fuel it's blended into, and serves to oxygenate diesel, leading to fewer harmful emissions. EEB can also be made using other organic waste products, such as corn stover, rice straw and distillers grains. EEB can be made for less than $4 a gallon and isn't subject to the maddening market fluctuations and international politics of fossil fuels. Furthermore, EEB's carbon footprint is 70 percent less than that of fossil fuels. Vitruvian also sees potential for EEB to be used on its own to power vehicles or burned to produce electricity for the grid. So far, Vitruvian Energy has used grants from the California Energy Commission and National Science Foundation to develop EEB, and has tested the fuel in a Pontiac Solstice at Oak Ridge National Laboratory. Now, Vitruvian is wants to test EEB on a larger scale in the real world in order to prove EEB's viability to interested parties in the wastewater treatment industry. In an Indiegogo crowdfunding campaign, Vitruvian Energy hopes to raise $200,000 to build a prototype EEB production line and to run a test vehicle for a year on an EEB-diesel blend on the streets of Seattle. Donors can score some interesting perks such as shirts and bumper stickers that say "Get Clean with Poopaline." Learn more about EEB in the video and press release below.

'67 Chevy Corvair convertible vs. '86 Pontiac Fiero in cult classic showdown

Every few a decades, the folks running General Motors lose their minds briefly try to market a car that public doesn't see coming and often aren't ready for. In the '60s there was the rear-engine, air-cooled Chevrolet Corvair, then the mid-engine Pontiac Fiero in the '80s and the completely bizarre Chevy SSR in the 2000s. What all of these had in common was that they bucked the trend for American models of their era, for better or worse. The latest episode of Generation Gap tasked the hosts with finding two cult classic vehicles to choose between; they came come up with two of these quirky products from The General.
On the classic side, there's a 1967 Chevy Corvair Monza convertible. Being from later in the production run, it wears slightly more aerodynamic styling than the earlier, boxier examples. Hanging out back is an air-cooled, 2.7-liter flat-six pumping out a robust 95 horsepower. In the other corner is the somewhat more modern 1986 Pontiac Fiero SE with a mid-mounted, 2.5-liter "Iron Duke" four-cylinder, an engine nearly ubiquitous in GM cars of the '80s.
Judging by when they were new, the Corvair was far more successful than the Fiero with over 1.8 million sold. Of course, Ralph Nader's book Unsafe at Any Speed kind of poisoned the well, even if the poor safety reputation wasn't entirely deserved. The Fiero on the other hand only lasted for a few model years before shuffling off, but it eventually got its own performance boost with the V6 version and rather attractive GT models. Check them both out in the video and tell us in Comments which you want in your garage.

Motorweek looks back at the Pontiac Aztek

The Pontiac Aztek has earned a position as this generation's ultimate, automotive punchline. Even other execrable models like the Yugo or Mustang II probably get more respect these days just out of their sheer quirkiness, but the Aztek remains a joke. Fortify your mind for what's coming, though, because the much-maligned Pontiac might not be quite so atrocious, at least according to MotorWeek's latest Retro Review video. MotorWeek calls the Aztek, "GM's first true crossover vehicle," and it's amazing to think of the hated model as a progenitor of one of the most popular segments today. While admitting that the looks are polarizing, John Davis and company actually come away pleased with the Aztek's utility. They praise that there's a ton of room in the back, and the interior is packed with useful features like a removable cooler in the center console and radio controls in a cargo area. The show is even impressed with how the Pontiac drives and throws around accolades like "nimble" and "pleasant." After seeing the Aztek leading the pack on lists of the worst vehicles of all time for years, listening to it get such effusive praise is actually quite jarring. Could we all be so wrong? No, there's absolutely no debate that this is still a hideous automobile. However, MotorWeek asserts a complete reversal of the generally perceived wisdom about the early CUV. While unexpected, thinking about such an abhorred model in a different way is a cool experience. Check out the video for a different take on the Aztek.
