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.

Looking back at Oprah's free-car giveaway 10 years later

Oprah kicked off her 19th season in dramatic fashion by giving all 276 members of the studio audience a free car.
Molly Vielweber's Pontiac G6 appears unremarkable at first glance. It wears forest green paint, rolls on five-spoke aluminum wheels, and it has a sizeable scrape in the driver's side door, the scar of a decade's worth of hard use. You wouldn't notice it parked at a big box store or cruising on the highway. Pontiac made hundreds of thousands of G6s in the 2000s, and a lot are still on the road. It's unremarkable in every way except for the front license plate, which reads, "Oprah 6."

What car brand should come back?

Congratulations, wishful thinker! You've been granted one wish by the automotive genie or wizard or leprechaun or whoever has been gifted with that magical ability. You get to pick one expired, retired or fired automotive brand and resurrect it from its heavenly peace! But which one? That's a tough decision and not one to be made lightly. As we know from car history, the landscape is littered with failed brands that just didn't have what it took to cut it in the dog-eat-dog world of vehicle design, engineering and marketing. So many to choose from! Because I am not a car historian, I'll leave it to a real expert to present a complete list of history's automotive misses from which you can choose, if you're a stickler about that sort of thing. And since I'm most familiar with post-World War II cars and brands, that's what I'm going to stick to (although Maxwell, Cord and some others could make strong arguments). So, with the parameters established, let's get started, shall we? Hudson: I admit, I really don't know a lot about Hudson, except that stock car drivers apparently did pretty well with them back in the day, and Paul Newman played one in the first Cars movie. But really, isn't that enough to warrant consideration? Frankly, I think the Paul Newman connection is reason enough. What other actor who drove race cars was cooler? James Dean? Steve McQueen? James Garner? Paul Walker? But, I digress. That's a story for another day. Plymouth: As the scion of a Dodge family (my grandfather had a Dodge truck, and my mom had not one, but two Dodge Darts – the rear-wheel-drive ones with slant sixes in them, not the other one they don't make any more), I tend to think of Plymouth as the "poor man's Dodge." But then you have to consider the many Hemi-powered muscle cars sold under the Plymouth brand, such as the Road Runner, the GTX, the Barracuda, and so on. Was there a more affordable muscle car than Plymouth? When you place it in the context of "affordable muscle," Plymouth makes a pretty strong argument for reanimation. Oldsmobile: When I was a teenager, all the cool kids had Oldsmobile Cutlasses, the downsized ones that came out in 1978. At one point, the Olds Cutlass was the hottest selling car in the land, if you can believe that. Then everybody started buying Honda Civics and Accords and Toyota Corollas and Camrys, and you know the rest. But going back farther, there's the 442 – perhaps Olds' finest hour when it came to muscle cars.
