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.

Porsche Boxster Spyder to get GT3's 4.0-liter flat six?

It's been a merry-go-round the past few months, the rumormill focused on what will power the next Porsche Boxster Spyder. First came hearsay of a flat-six going into the special edition of a model line known for its turbocharged four-cylinder engines. Then came tattling that the flat-six in question was the naturally aspirated, 4.0-liter from the 911 GT3. A couple of weeks ago we wrote " we'd be surprised if Porsche packed anything other than a turbocharged flat-four under the skin." But Autocar has a new report that, indeed, a downtuned version of the 500-horsepower 4.0-liter from the GT3's rump will move to the Boxster Spyder's midsection. The Autocar piece follows a Wheels magazine article from last November, and the prediction isn't outrageous. When Car and Driver reviewed the last Boxster Spyder, it wrote, "the hand-me-down six comes from the older 911 Carrera S, not to be confused with the new turbocharged 3.0-liter flat-six that powers the refreshed 911." If we can believe a recent report from Automobile about the 992-series 911 due later this year, the same thing is happening: The 991.2-series GT3 bequeaths its powerplant to the smaller sibling, and the 992-series GT3 moves to a 3.8-liter, twin-turbo flat-six with around 550 hp. Autocar quotes Andreas Preuninger, the Porsche engineer leading the development of all of these wunderkinds, saying of the Boxster earlier this year, "Natural aspiration is one of our main USPs. ... [We] think we can achieve throttle response and immediacy a little bit better with an atmospheric high-revving engine than any kind of turbo." We'll guess that means, by inference, that the GT3 is about to age out of naturally-aspirated university. The limited-edition Boxster Spyder might carry the torch with the 4.0-liter, with output somewhere around 430 hp. The Cayman GT4 could do the same. Or, who knows, an evolution of the 375-hp, 3.8-liter flat-six in the previous Boxster Spyder might burble out of left field. We expect to see the Boxster Spyder late this year. Until then, we'll wait to see what the merry-go-round says next time the Zuffenhausen horse comes around.

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.
