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.

What's driving the spike in air-cooled Porsche 911 prices

Classic car prices have been racing skyward in general, but prices for air-cooled (pre-1999) Porsche 911s are ascending like they're strapped to rocket boosters. It's been going on for years, and every year people are surprised by how outrageous it's getting: Classic Driver covered it this month, as did The Truth About Cars who included this example of a "scruffy" 1993 RS America with 215,000 miles asking $80K; Mike Spinelli at Drive riffed on it at length last year along with a host of classic-car-market observers; Porsche forums were at it two years ago; and let's not even get into the 993 Turbo, going for prices so high you have to lie down to look at them. Speed Academy has run a piece looking at why it's happening, one theory being that regular-guy owners are hopping on the runaway-price wagon without any good reason. As in the example of that high-mileage, scruffy 911 RS America at Bring a Trailer, the owner sees pristine examples valued by Hagerty at $170,000, and even though the average value is $93,238 he thinks something like, "Mine's got to be worth half of top dollar ..." The tide - even one rising on air - makes it hard to find decent prices. Then there is the flood of money into the market. In spite of articles that try to temper investors' outlooks on collectible cars, other articles in places like the Financial Times and the Guardian promote vintage metal as a safe place to put money and reap astonishing returns. Speed Academy thinks one side effect of high 911 prices is that responsible enthusiasts are turning their attention to cars like the BMW 2002, E30 M3, and E9 3.0CS, saying their prices are "sharply on the rise." The entire article is worth a read since it goes into markets far afield from pricey German steel, but incredibly, the entire piece was actually inspired by a 1997 Acura Integra R that sold for $43,000 on eBay. So while this could be the best time to get into the classic car market if you know what you're doing, it is certainly the best time to do your homework. Related Video:

This or That: 2005 Chrysler Crossfire SRT6 vs. 1984 Pontiac Fiero

Welcome to another round of This or That, where two Autoblog editors pick a topic, pick a side and pull no punches. Last round pitted yours truly against Associate Editor Brandon Turkus, and my chosen VW Vanagon Syncro narrowly defeated Brandon's 1987 Land Rover. In fact, it was, by far, the closest round we've seen, with 1,907 voters seeing things my way (for 50.8 percent of the vote) versus 1,848 votes for Brandon's Rover (49.2 percent). Sweet, sweet victory! For this latest round of This or That, I've roped Editor Greg Migliore into what I think is a rather fun debate. We've each chosen our favorite terrible cars, setting a price limit of $10,000 to make sure neither of us went too crazy with our automotive atrocities. I think we've both chosen terribly... and I mean that in the best way possible. 2005 Chrysler Crossfire SRT6 Jeremy Korzeniewski: Why It's Terrible: Taken in isolation, the Chrysler Crossfire isn't necessarily a terrible car. In fact, it drives pretty darn well, and there's a lot of solid engineering under its slinky shape. Problem is, that engineering was already rather long in the tooth well before Chrysler ever got its hands on it, having come from Mercedes-Benz, which used the basic chassis and drivetrain in a previous version of its SLK coupe and roadster. Granted, the SLK was an okay car, too, but even when new, it hardly set the world on fire with sporty driving dynamics. Chrysler took these decent-but-no-more bits and pieces from the Mercedes parts bin – remember, this car was conceived in the disastrous Merger Of Equals days – and covered them with a rather attractive hard-candy shell. Unfortunately, the super sporty shape wrote checks in the minds of buyers that its well-worn mechanicals were simply unable to cash, though an injection of power courtesy of a supercharged V6 engine in the SRT6 model, as seen here, certainly helped ease some of those woes. In the end, Chrysler was left with a so-called halo car that looked the part but never quite performed the part. It was almost universally panned by critics as an overpriced parts-bin special, which, I must add, was damningly accurate. As a result, sales were very slow, and within the first few months, dealers were clearancing the car at cut-rate prices, just to keep them from taking up too much of the showroom floor. Why It's Not That Terrible, After All: I can speak from personal experience when discussing the Chrysler Crossfire. You see, I owned one. Well, sort of...
