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.

Motorweek looks back at the Pontiac Aztek

The Pontiac Aztek has earned a position as this generation's ultimate, automotive punchline. Even other execrable models like the Yugo or Mustang II probably get more respect these days just out of their sheer quirkiness, but the Aztek remains a joke. Fortify your mind for what's coming, though, because the much-maligned Pontiac might not be quite so atrocious, at least according to MotorWeek's latest Retro Review video. MotorWeek calls the Aztek, "GM's first true crossover vehicle," and it's amazing to think of the hated model as a progenitor of one of the most popular segments today. While admitting that the looks are polarizing, John Davis and company actually come away pleased with the Aztek's utility. They praise that there's a ton of room in the back, and the interior is packed with useful features like a removable cooler in the center console and radio controls in a cargo area. The show is even impressed with how the Pontiac drives and throws around accolades like "nimble" and "pleasant." After seeing the Aztek leading the pack on lists of the worst vehicles of all time for years, listening to it get such effusive praise is actually quite jarring. Could we all be so wrong? No, there's absolutely no debate that this is still a hideous automobile. However, MotorWeek asserts a complete reversal of the generally perceived wisdom about the early CUV. While unexpected, thinking about such an abhorred model in a different way is a cool experience. Check out the video for a different take on the Aztek.

A pair of Mitsubishis, the Mazda CX-30 and electric incentives | Autoblog Podcast #673

This week's Autoblog Podcast features Editor-in-Chief Greg Migliore and Consumer Editor Jeremy Korzeniewski as they debate the merits of the redesigned Subaru BRZ and Toyota 86 coupes and whether or not they are distinctive and powerful enough to attract buyers. The duo spends some time discussing ongoing EV and infrastructure legislation before turning their attention to a trio of crossovers. Greg muses about the 2021 Mazda CX-30 before Jeremy talks about the refreshed 2022 Mitsubishi Eclipse Cross and completely redesigned Outlander. We get nostalgic as we remember the dearly departed Pontiac GTO before wrapping the podcast up by making one more suggestion to a longtime listener who is shopping for a vehicle to replace her aging Honda Pilot.
