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.

This classic Firebird restomod swallowed a Prius

It takes an unusual eye to look at a 1967 Pontiac Firebird and see the Toyota Prius hidden inside. But that's just the kind of eye that a creative mechanic known online as "Bill the Engineer" has. Bill is updating his old Firebird into a true classic for the 21st century and has documenting the changes over at Priuschat and EcoModder. The TL,DR version of the story: he's replacing the worn-out powertrain with the gas-electric hybrid one from a Prius V, because it turns out the two vehicles have almost exactly the same wheelbase. Bill, who's from Columbus, Ohio and doesn't want his full name used, said in his posts on the conversion project that he's made many memories with this vehicle since buying it back in 1979. Since then, a few moves, a few decades, and some time in storage meant that the car would no longer function as he wanted it to. As he wrote, "when it comes to mice in the vehicles IT IS WAR." His solution is to make new memories and making a greener vehicle, and so we wanted to ask him how things have been going. Bill's been traveling a bit recently, but told AutoblogGreen that he's now figuring out the next steps for this amazing and complicated project. "I always plan things out before I do them," he said. That's the only way something like this can work. ABG: I think we have to start with what gave you the inspiration for this project. Was it simply that you had the two cars and wanted to see them merged into one cool mashup, or was it something else? "One day my wife wondered out loud if the car could be converted into a hybrid... The rest is history." Bill: I have been the owner of my 1967 Firebird convertible since 1979 when I bought it for $750.00. I drove it for years and made many memories. Afterward it was in storage for many years during which time mice at their way into the car and trashed the interior and wiring. I started working on a conventional restoration but always ran into major problems with hidden corrosion, electrical issues and an engine on its last legs. The car was never going to be as nice as I wanted going the conventional route. One day my wife wondered out loud if the car could be converted into a hybrid like our two daily driver Prii. That got me thinking about how it could be done. The rest is history... ABG: It looks like you started in late 2014. Have things gone well since then, or has it been one hassle after another? What has been the biggest setback, and what were the biggest victories?
