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.

The last Pontiac Fiero sold for $90,000 at auction

On August 16, 1988 the last Pontiac Fiero, a red GT model, rolled off the assembly line at GM's Pontiac Assembly plant located in Pontiac, Michigan. It wasn't just the final Fiero, but the final car to be built at that site. The car was raffled off to one of 1,400 plant employees that would soon have to find jobs elsewhere. Whoever that employee was, they remained faithful to the Fiero and kept it in mint condition for 32 years. Last month, it was finally time to move on. It crossed the block at GAA Auctions in Greensboro, North Carolina where it sold for an astounding $90,000. According to the auction house, that's a new world record. The price no doubt reflected the car's place in history as the last example of GM's 1980s mid-engined sports car. However, it was also showroom-new, with just 582 miles clocked on its 2.8-liter V6. 1988 models were also fitted with an upgraded, Lotus-esque suspension produced for just that one year. In addition, this car, serial number 226402, came with its original build sheet, photos from the assembly line, and a collection of news articles and books. It still wore its pre-delivery plastic on the interior and was fully loaded with automatic transmission. This content is hosted by a third party. To view it, please update your privacy preferences.

You can see the action starting at the 2:50:13 mark in the video above. The Fiero was symbolic of the 1980s and stood out from the standard GM passenger car fare for its mid-engine layout and plastic body panels. In an era when GM often rebadged cars with minimal differences, the Fiero rode on its own unique chassis. It was positioned as one of the defining products for Pontiac, GM's "excitement" brand, but actual performance never quite lived up to its striking looks.  Nevertheless, it garnered a cult following. It's often the basis for (questionable) custom builds mimicking more exotic models like Ferraris and Lamborghinis, thanks to a steel space-frame design that allows body panels to be easily removed. Thankfully, this significant example escaped such a fate and will live on as a reminder of an interesting chapter of automotive history.

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.
