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.

Rent the 1967 Pontiac GTO from the XxX films now on Turo

The process of renting a car usually ranges from mildly annoying to "I'm calling corporate to get you fired." Plainly, it sucks, but sometimes you're left with no alternative. Turo, a peer-to-peer carsharing network, has created what's essentially the AirBnB for cars. Like AirBnB, the quality and variety of the rides varies based on location. If you're in Tucson, Ariz., in the next week, go check out this 1967 Pontiac GTO convertible before the release of XxX: The Return of Xander Cage. Promotions and marketing aside, this is still the opportunity to drive one of the original muscle cars. It's not clear if this is an original GTO or a Pontiac Tempest that was converted, but does it really matter? Old cars never drive as well as you hope, so, as long as it looks and sounds awesome, who cares? The owner listed on Turo is Xander C., Vin Diesel's character from the XxX franchise. This is the car that was used in the original 2002 film, and from the photos it appears to be in better shape than many other movie cars. The exterior is mostly stock, with some slight modifications to the lighting, wheels, exhaust, and trim, with the addition of a funky looking hood scoop that the listing claims shoots flames. It's not clear if it functions as an actual intake because there aren't any notes about what rests under the hood. The listing does ask for premium fuel, so more than likely it's some variation of a high-compression V8. Inside, the dashboard looks like someone raided the AutoZone accessory aisle. There are gauges, dials, toggle switches, and readouts galore. The listing also claims the Goat is packing a rocket launcher and a weapons stash under the seat. $999 per day isn't cheap, but it's less than you'd pay for a day with one of the rent-an-exotic shops you see in Los Angeles or New York. If you're not in Tucson or the price is a little too steep, Turo has what it's dubbed the Adrenaline Collection. The name may be hyperbole, but the lineup of cars is actually really solid. A quick glance reveals a 2015 Lamborghini Huracan, 2001 Ferrari 360 Spider, and a 1969 Jaguar E-Type. The car list keeps expanding, so if this proves popular, look for more cool stuff in the future.
