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.

Junkyard Gem: 2001 Pontiac Aztek

Ah, the Pontiac Aztek. Everyone laughs at the Aztek ... except, apparently, for Coloradans who like to go camping, bike riding, hiking, and all that outdoorsy stuff that folks do in the Centennial State. You'll see Azteks being driven, unironically and without shame, all over the place in the Denver region, and now plenty of them are showing up in the local wrecking yards. Here's a first-year-of-production example in its final campground. These minivans or crossovers (or however the experts finally decided to categorize them) had built-in air compressors, audio controls in the rear cargo area, and other features meant to enhance tailgating, camping, and other activities deemed central to Generation X's allegedly active lifestyle. You could even get an optional camping kit with a tent that attached to the rear of the Aztek. So, it was a General Motors minivan-like vehicle, cousin of the weird-looking Dustbusters of the 1990s, with lots of useful features for those who did more than just commute to work and drop off kids at school. Unfortunately for GM, the Aztek was staggeringly ugly, and Generation Xers were too damned broke to buy new cars in 2001, anyway. I see plenty of them in Denver-area wrecking yards now, along with their slightly-less-offensive-looking Buick Rendezvous siblings, and so I decided to document one before they're all gone.

Junkyard Gem: 1992 Pontiac Firebird

Last spring, this series featured a 1992 Chevrolet Camaro RS in a Northern California junkyard, an example of the final model year for the highly successful third-generation GM F-Body. On a later visit to that yard, I spotted the Pontiac sibling to that car, a Firebird that was born the same year at the same Southern California factory. When the Chevrolet Division introduced the first Camaro as a 1967 model, the Pontiac Division got its own version of the F-Body called the Firebird. While the two cars were built on the same chassis and looked very similar, the first-generation Camaros got Chevrolet engines while their Firebird colleagues got Pontiac engines (including the innovative SOHC straight-six). The 1970-1981 second-generation Firebirds still had some Pontiac-only engines, but Chevrolet and Oldsmobile power crept under some hoods during that period. The third-generation Firebirds first appeared as 1982 models, and they drew from near-identical stockpiles of GM running gear (including the distinctly agricultural Iron Duke four-banger, which could be considered a Pontiac-derived engine). When the Camaro got the axe after 2002, the Firebird's neck was put on the same chopping block. When the Camaro returned for 2010, the Pontiac brand was sputtering to an agonized halt during its final year and there was no chance of the Firebird's return. This car is a fairly ordinary coupe, though it does have the mid-grade 205-horsepower 5.0-liter Chevrolet small-block V8 instead of the base 140-horse 3.1-liter V6. A 5.7-liter small-block was available as well. A five-speed manual transmission was base equipment, but few Americans wanted a three-pedal setup by the early 1990s. This car has the optional four-speed automatic. The MSRP with 5.0 engine, automatic transmission and air conditioning (which this car has) started at $14,304. That's about $31,868 in 2023 dollars. It was built at Van Nuys Assembly in the San Fernando Valley of Los Angeles County. By the dawn of the 1990s, the Camaros and Firebirds made at Van Nuys Assembly had become known as the worst-built GM cars made in North America, and the plant was shut down forever soon after this car was built. Today, a shopping mall lives where the factory once stood. This car managed to drive more than 150,000 miles during its life, so it beat the odds. The thrid-gen F-Body was pretty antiquated by the early 1990s, but the fourth-gen cars handled better and looked up-to-date for the era.
