Junkyard Gem: 2002 Pontiac Aztek

The General's Pontiac Division sold the Aztek for the 2001 through 2005 model years, and — despite enjoying something of a cultural rebirth in recent years — it is generally considered to be one of the worst cars of all time. The idea of using a minivan platform as the basis for a rough-and-tough-looking crossover with plenty of outdoor-lifestyle amenities wasn't the problem, since many vehicle manufacturers have printed bales of money using that formula. What doomed the Aztek was its hideous appearance and sticker price too lofty for its underemployed-at-the-time Generation X target demographic. Still, the Aztek proved to be perfectly suited for the outdoor activities that Coloradans love: hiking, camping, fishing, skiing, hauling mud-caked golden retrievers around, etc., and so you'll still find lots of Azteks on the roads of the Centennial State. Here's an Aztek Yellow Aztek (yes, that's really the paint color's official title) residing just a few rows from a '76 Checker Taxicab in a Denver self-service yard. Sure, it does look like a vehicle built to the specifications of a six-year-old who decreed a mashup between a Datsun F-10 and a Fisher-Price Little People Travel Together Airplane, but so what? There's a built-in air compressor to blow up your inflatable rafts and volleyballs, a tent attachment that turns the rear of the van into a camper, 12-volt power plugs all over the vehicle (years before this became commonplace on ordinary minivans and SUVs), and running-gear commonality with a jillion Ventures, Silhouettes, Montanas and Trans Sports. Buick managed to de-uglify the Aztek (somewhat) and sold it as the Rendezvous through 2007, but the Aztek never could win over many people with this face. I see plenty of Azteks and Rendezvouses in Denver-area wrecking yards, and I've documented a handful over the years. This one came fully loaded from the factory, with the Corvette-style heads-up display in full effect. The center console was a removable cooler, which was a great idea Â… except for the fact that this cooler holds five standard 12-ounce cans. Michigan residents tell me that this must have been intentional on the part of the Detroit-based Aztek designers, because Michiganders are expected to chug one beer out of a sixer as they walk from the liquor store to the car in the parking lot Â… which makes me extra cautious whenever I'm driving in the Wolverine State.

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: 1989 Pontiac 6000 STE AWD

During the middle to late 1980s, General Motors made a big push to grab back some of the sales swiped by makers of European luxury machinery during the previous decade. Around the top of the prestige pyramid, there was the Turin/Hamtramck-built Cadillac Allante taking aim at the Mercedes-Benz 560SEC and the super high-tech Buick Reatta trying to seduce away BMW and Jaguar shoppers; even the Riviera offered a futuristic touchscreen computer sorely lacking in anything out of Stuttgart or Bavaria. The General had a plan to take on the smaller German sporty sedans, too, and Pontiac of the "We Build Excitement" era offered a midsize sedan packed with modern hardware at a great price: the 6000 STE. Here's one of the rarest 6000 STEs of them all, an all-wheel-drive-equipped '89 found in a Denver-area yard last week. Any 6000 STE is extremely hard to find today; when I wrote about a front-wheel-drive 1987 6000 STE back in 2018, desperate owners of these cars filled my inbox with requests — sometimes demands —  for parts that continue to this day. Many of them pleaded with me to help them find an all-wheel-drive version, and now I have managed to find one at Colorado Auto & Parts in Englewood, just south of Denver (in fact, the same yard at which I shot the '87). You may recall CAP as the old-school yard whose owners built the amazing airplane-engined 1939 Plymouth pickup a few years back.  The all-wheel-drive system on the 6000 STE was introduced for the 1988 model year, and it became standard equipment on the 1989 STE. At this time, the automotive industry had taken note of the success of the idiot-proof all-wheel-drive systems offered by AMC and Audi/Volkswagen; Toyota began selling Americans all-wheel-drive Camrys, Celicas, and Corollas, while Ford offered the Tempo and Topaz with optional AWD and Subaru was just beginning to make the switch from manually-selected four-wheel-drive to genuine all-wheel-drive around that time (it took a few more years for everyone to standardize on the 4WD/AWD terminology we use today, though). The 6000 STE AWD was intended to compete with such all-wheel-drive-equipped sedans as the Audi 80 ($23,610), Audi 90 ($28,840), and BMW 325iX ($30,750); its $22,599 price tag (about $50,700 in 2021 dollars) certainly made it seem like a bargain compared to those cars. In addition to the all-wheel-drive system, 1989 6000 STE owners got a digital instrument panel and more switches and buttons than the Space Shuttle.
