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: 1997 Pontiac Sunfire SE Convertible

For the entire 24-year production run of the GM J platform (best known for the Chevrolet Cavalier), the Pontiac Division offered new J-Body cars for sale in the United States. First there was the J2000, followed in quick succession by the 2000, 2000 Sunbird and Sunbird. The Sunbird stuck around until the Cavalier got a major redesign for the 1995 model year, at which point Pontiac changed the car's name to Sunfire. Today's Junkyard Gem is one of those early Sunfires, a top-of-the-line SE convertible with the optional big engine and manual transmission. The Sunfire was an extremely close sibling to the same-year Cavalier (by the late 1980s, all the other US-market GM divisions had dropped their J-cars, which meant no more Skyhawks, Cimarrons or Firenzas), quite difficult to distinguish from its near-twin at a glance. The base engine for the 1997 Sunfire convertible was the pushrod 2.2-liter straight-four that powered so many J-bodies of the 1990s. That engine produced just 120 gnashing, valve-floating horsepower, not much by late-1990s standards. For a mere 450 additional dollars, however, the 2.4-liter Twin Cam engine and its high-revving 150 horses could be had by '97 Sunfire buyers. That's what's in this car. This is one of the members of the Oldsmobile Quad 4 family, though some fanatics will yell at you if you apply that name to the versions that don't have big QUAD 4 lettering cast into the valve cover. This is the most powerful engine ever used in production Sunfires. For 1997, Pontiac offered a four-speed automatic transmission for no extra cost in the Sunfire convertible. Buyers of all other Sunfire models that year had to shell out either $550 or $810 ($1,026 or $1,511 in 2023 dollars) for a two-pedal rig. That means that the buyer of this car really wanted the five-speed manual transmission (or just hungered for the $810 credit offered in the fine print for takers of the manual). Plenty of free-breathing engine power, five-on-the-floor driving enjoyment and the open skies above. What a fun car! This one made it to nearly 180,000 miles. For this car with the Quad 4 under the hood and a clutch pedal on the floor, the MSRP was $18,539 (about $34,584 today). Its Cavalier LS convertible twin with the same engine/transmission setup cost $17,365 ($32,394 now). This car has a bunch of options, including the 15" Rally aluminum wheels, so the out-the-door price would have been higher. The last year for the Sunfire was 2005, same as the Cavalier.
