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.

Here are a few of our automotive guilty pleasures

It goes without saying, but I'll say it anyway. The world is full of cars, and just about as many of them are bad as are good. It's pretty easy to pick which fall into each category after giving them a thorough walkaround and, more important, driving them. But every once in a while, an automobile straddles the line somehow between good and bad — it may be hideously overpriced and therefore a marketplace failure, it may be stupid quick in a straight line but handles like a drunken noodle, or it may have an interior that looks like it was made of a mess of injection-molded Legos. Heck, maybe all three. Yet there's something special about some bad cars that actually makes them likable. The idea for this list came to me while I was browsing classified ads for cars within a few hundred miles of my house. I ran across a few oddballs and shared them with the rest of the team in our online chat room. It turns out several of us have a few automotive guilty pleasures that we're willing to admit to. We'll call a few of 'em out here. Feel free to share some of your own in the comments below. Dodge Neon SRT4 and Caliber SRT4: The Neon was a passably good and plucky little city car when it debuted for the 1995 model year. The Caliber, which replaced the aging Neon and sought to replace its friendly marketing campaign with something more sinister, was panned from the very outset for its cheap interior furnishings, but at least offered some decent utility with its hatchback shape. What the two little front-wheel-drive Dodge models have in common are their rip-roarin' SRT variants, each powered by turbocharged 2.4-liter four-cylinder engines. Known for their propensity to light up their front tires under hard acceleration, the duo were legitimately quick and fun to drive with a fantastic turbo whoosh that called to mind the early days of turbo technology. — Consumer Editor Jeremy Korzeniewski  Chevrolet HHR SS: Chevy's HHR SS came out early in my automotive journalism career, and I have fond memories of the press launch (and having dinner with Bob Lutz) that included plenty of tire-smoking hard launches and demonstrations of the manual transmission's no-lift shift feature. The 260-horsepower turbocharged four-cylinder was and still is a spunky little engine that makes the retro-inspired HHR a fun little hot rod that works quite well as a fun little daily driver.

Fiero-based Zimmer Quicksilver was objectively terrible, but we'd totally drive it

Now here's something you don't see everyday. It's listed in our classified ads as a 1986 Pontiac Fiero, but as you can see, that description is a bit misleading. In fact, it's a Zimmer Quicksilver, which was indeed built atop the guts of a mid-engine Fiero coupe but was heavily modified by the Zimmer Motorcars Corporation at a facility in Pompano Beach, Florida. And the one you see here actually seems to be a pretty decent deal for a highly unusual car. We're not sure what was a more popular starting point for kit and custom cars in the 1980s and 1990s, but it would have to be either the Fiero or the vintage air-cooled Volkswagen Beetle. Fiero-based machines usually mimicked the design direction of any number of highly desirable Italian stallions, most commonly, we'd guess, the Lamborghini Countach. The Quicksilver is an altogether different animal, with over a foot of extra wheelbase added in front of the A-pillar to make for a dramatic, long and low silhouette that somehow still only has barely enough room for two passengers in its leather- and wood-lined interior.

A stock 2.8-liter V6 engine from General Motors is mated to a three-speed automatic transmission that sends 140 horsepower and 170 pound-feet of torque to the rear wheels. Period road tests found the 0-60 run took a little over 10 seconds, which is terrible today but wasn't all that bad for the mid '80s. Best we can tell, only around 170 Quicksilvers were made between 1984 and 1988, which are, not coincidentally, the same years that Pontiac produced the Fiero. The 1986 Zimmer Quicksilver you see here is priced at $18,495 and shows well under 30,000 miles on the odometer. There aren't a lot of Zimmer Quicksilvers currently for sale for us to compare, but the ones we did find that had sold within the last few years suggest a little under $20,000 is a reasonable asking price. It could be a fun and offbeat addition to the garage, and if nothing else, you're not likely to see another one at your local car show. Related video: This content is hosted by a third party.
