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: 1984 Pontiac Fiero with supercharged 3800 V6 swap

Like the Corvair, the Vega, and the Citation, the Pontiac Fiero was a very innovative machine that ended up causing General Motors more headaches than happiness, and Fiero aficionados and naysayers continue to beat each other with tire irons (figuratively speaking, I hope) to this day. The General has often proved willing to take the occasional big gamble and huge GM successes in engineering prowess (including the first overhead-valve V8 engine for the masses and the first real-world-usable true automatic transmission) and marketing brilliance (e.g., the Pontiac GTO and related John DeLorean home runs) meant that the idea of a mid-engined sporty economy car (or economical sports car) got a shot from the suits on the 14th floor. Sadly, the Fiero ended up being the marketplace victim of too many issues to get into here, and The General pulled the plug immediately after the 1988-model-year suspension redesign that made the Fiero the sports car it should have been all along. But what if the plastic Pontiac had never suffered from the misery of the gnashy, pokey Iron Duke engine and had been built from the start with a screaming supercharged V6 making way better than 200 horsepower? The final owner of today's Junkyard Gem sought to make that very Fiero, by dropping in one of the many supercharged 3.8-liter V6s installed in 1990s and 2000s GM factory hot rods. The first Fieros came out in 1983 for model year 1984, and the only engine available that year was the Iron Duke 2.5-liter four-cylinder, which generated its 92 horsepower with the full-throated song of a Soviet tractor stuck in the freezing mud of a Polish sugar-beet field. The 2M4 badging stood for "two seats, mid-engine, four cylinders," just as the numbers in the Oldsmobile 4-4-2 once represented "four carburetor barrels, four-speed manual transmission, dual exhaust." This car is a top-trim-level SE model, which listed for $9,599 (about $24,200 today). The no-frills Fiero cost just $7,999 that year, making these cars far cheaper than the only other reasonably affordable new mid-engined car Americans could buy at that time: the $13,990 Bertone (aka Fiat) X1/9. The Toyota MR2 appeared in North America as a 1985 model with a base price of $10,999 and promptly siphoned off the car-buying cash from a bunch of potential Fiero shoppers.

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.
