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."

GM replacing passenger airbags in over 243,000 Pontiac Vibes

General Motors is repairing over 243,000 additional examples of the 2003-2007 Pontiac Vibe in the US and Canada to replace their Takata-supplied passenger-side airbag inflators. The company has no reports of irregular deployments in the models, though. These aren't actually newly included vehicles in the massive safety campaign. As a twin to the Toyota Matrix, the Vibe was already included in Toyota's figures, but as Pontiac-branded vehicles, GM dealers are taking care of these replacements. They have been covered as part of the Takata campaign in the past. Toyota expanded its own Takata recall to passenger-side components for 1.365 million vehicles on June 16. Earlier, General Motors also issued a campaign for 330,198 examples of the 2007 and 2008 Chevrolet Silverado 2500HD, 3500HD, GMC Sierra 2500HD, and 3500HD pickups to replace their passenger-side parts. After exposure to moisture, it's possible for these inflators to ignite too quickly in an accident and spray shrapnel at occupants. GM Statement The Vibes are included in two Toyota recall campaigns - one for high absolute humidity (HAH) areas and one for non-HAH areas. Both are considered national recalls even though only vehicles in certain HAH states and territories are in the recall. Total Pontiac Vibe passenger air bag numbers for MY 2003-2007 (U.S. and Canada only): High Absolute Humidity 89,719 Non High Absolute Humidity areas 252,685 These are the totals, which include about 99,000 previously recalled. GM knows of no field issues - irregular deployments - with these air bag inflators.
