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.

Best and Worst GM Cars

Oh yes, because we just love receiving angry letters from devoted Pontiac Grand Am enthusiasts, we have decided to go there. Based on a heated group Slack conversation, the topic came up about the best and worst GM cars. First of all time, and then those currently on sale, and then just mostly a rambling discussion of Oldsmobiles our parents and grandparents owned (or engineered). Eventually, three of us made the video above. Like it? Maybe we can make more. Many awesome GM cars are definitely going unmentioned here, so please let us know your bests and worsts in the comments below. Mostly, it's important to note that this post largely exists as a vehicle for delivering the above video that dives far deeper into GM's greatest hits and biggest flops, specifically those from the 1980s and 1990s. What you'll find below is a collection of our editors identifying a best current and best-of-all-time choice, plus a worst current and worst-of-all-time choice. Comprehensive it is not, but again, comments. -Senior Editor James Riswick Best Current GM Vehicle Chevrolet Corvette We were flying by the seats of our pants a bit in this first outing and my notes were similarly extemporaneous. When it came time to tie it all together on camera, I failed spectacularly. Thank the maker for text, because this gives me the opportunity to perhaps slightly better explain my convoluted reasoning. I chose the C8 Corvette because it's simply overwhelmingly good, and it's merely the baseline from which this generation of Corvette will be expanded.  While the Cadillac CT5-V Blackwing (more on that in a minute) is an amazing snapshot of GM's current performance standing and its little sibling so enraptured me that I went out and bought one, their existence is fleeting. Corvette will live on; forced-induction Cadillac sport sedans, not so much. So while all three are amazing machines when viewed in a vacuum, the Corvette stands above them as both a reflection of GM's current performance credentials and a signpost of what is to come. So, given the choice between the C8 and the 5V-Blackwing right now, I'd choose the C8. In 10 years, when the Blackwing is no longer in production and Corvette is in its 9th generation? Well, that might be a different story. Now, just pretend I said something even remotely that coherent when we get to the part of the video where I try to make an argument for the 5-V Blackwing as best GM car I've ever driven. Or just laugh at me while I ramble incoherently.

Junkyard Gem: 1986 Pontiac Fiero GT

If you like affordable, mid-engined two-seaters, the 1980s were your decade. Fiat (and, a bit later, Bertone) offered the X1/9, Toyota sold MR2s, and even General Motors got into the act by creating the Fiero. Available from the 1984 through 1988 model years, the Pontiac Fiero showed plenty of promise but ended up being mostly disappointing, in some ways echoing the career of the Chevy Corvair of a couple of decades earlier. Today's Junkyard Gem is a once-spiffy 1986 Fiero GT, found in a self-service yard near Denver, Colorado. After a long and painful development period stretching all the way back to John DeLorean's XP-833 Banshee (which ended up being a major influence behind the original Opel GT), the Fiero finally debuted in 1983 as a 1984 model. The top-of-the-model-range GT appeared the following year. The Fiero was built as a notchback coupe and as a fastback, with all the GTs being the latter type. I couldn't get the engine lid open, but this car would have left the assembly line (in Pontiac, Michigan) with a 2.8-liter V6 rated at 140 horsepower. This car has a five-speed manual transmission, making it a credible rival for Toyota's MR2.  The 1986 MR2 was less powerful than the Fiero GT (112 horsepower versus 140), but also scaled in significantly lighter (2,459 pounds against the Pontiac's 2,780 pounds). The MR2 also cost less, priced at $11,298 while the Fiero GT cost $12,875 (that's about $30,540 and $34,805, respectively, in inflation-adjusted 2022 dollars). Meanwhile, the $6,998 Honda Civic CRX two-seater lured away many potential Fiero buyers despite being a front-engined/front-wheel-drive car, and the $7,186 Ford EXP/Mercury LN7 also put a dent in Fiero sales. I can't find a price for the 1986 Bertone X1/9, but it cost a hard-to-believe $13,990 in 1984. GM still was using five-digit odometers in many vehicles by the middle 1980s, but this Fiero has a six-digit unit and thus we can see that it nearly achieved 150,000 miles during its driving career. The 1984-1987 Fiero suffered from a parts-bin suspension design, with the front suspension borrowed from the Chevrolet Chevette and the entire rear transaxle/suspension assembly lifted from the front end of the Chevrolet Citation. For the 1988 model year, GM finally spent the money to design an improved Fiero-specific suspension … and then promptly put a halt to production.
