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.

GM reintroduces Tripower name in the worst way possible

The story of General Motors' use of the Tripower moniker begins way back in 1957, when Semon E. "Bunkie" Knudsen, then General Manager of GM's Pontiac division, directed his engineers to inject more performance into his brand's line of V8-powered automobiles. Fuel injection was an option, but hot rodders flocked instead to Tri-Power (marketed way back when with a hyphen), which grafted a trio of two-barrel Rochester carburetors onto a single intake manifold. A legend was born. And that legend was born of performance. At idle and when full power wasn't required, Pontiac's Tri-Power system used just the middle carburetor, which helped make the setup easier to tune. Depending on the year and model, either a vacuum system or a mechanical linkage opened up the two outer carbs, thereby switching from two barrels to six, and allowing the engine to take in more fuel and air. And it was an easy marketing win – six barrels is better than four barrels, right? Because performance! So, when news filtered in that GM has resurrected the Tripower name, those of us who grew up attending classic car shows and wrenching on old Pontiacs did a double-take. And then we all collectively sighed. Turns out that today's Tripower refers to a trio of fuel-saving measures that include cylinder deactivation, active thermal management, and intake valve lift control, according to Automotive News. And, at least for now, it applies to GM's line of fullsize trucks powered by a 2.7-liter turbocharged four-cylinder engine. We're all for saving fuel whenever possible. And we have zero say in how any automaker chooses to market its products and technologies. But, we'll offer our two cents anyway: Relaunching a storied name from the past is fine. Relaunching a storied name from the past while completely overlooking the reasons the name got famous in the first place is only going to irritate the people who remember the name in the first place. Couldn't they just call this new technology package something else?

ThatÂ’s right. As a self-described automotive photography snob myself, I have to say that the photos of this GTO are far and away the best IÂ’ve ever seen on Omaze. And while youÂ’re over there, might as well enter the drawing. Who doesnÂ’t want that lean, green, muscle machine in their driveway? IÂ’m more of a fastback Mustang guy, and even I was drooling over that GTO.  Win a Restored 1969 Pontiac GTO - Enter at Omaze Here are the specs of the restored 1969 Pontiac GTO in question, according to Omaze: Maximum Seating: 5 Engine: 461 ci fuel-injected V8 Transmission: Tremec TKO600 5-speed manual Drivetrain: RWD  Exterior Color: Verdero Green Interior Color: Black Maximum Horsepower: 575 hp Maximum Torque: 620 lb-ft Approximate Retail Value: $100,000  Cash Alt: $75,000 Special Features: Butler Performance-built EFI 461, Fast EFI v2.1, 3.73 Gears with Eaton Posi Traction, Wilwood 6-piston brakes with hydroboost, Ridetech Coilovers and muscle bars, Chassis Works billet drop spindles, staggered 18” Budnik billet wheels, Budnik steering wheel IÂ’m not the only one on the Autoblog staff who thinks this restoration is worthy of a little praise. News Editor Joel Stocksdale picked it above all the other current Omaze offerings for our holiday staff picks post. HereÂ’s what he had to say: “There are an awful lot of ways to build a restomod. And a lot of those ways can be boring or tasteless. This one is neither. This is a seriously classy Pontiac GTO. Under the hood is a 461 cu. in. V8 from Butler Performance that's based on an actual Pontiac V8, not just another Chevy engine. The whole thing is subtle with a low-key metallic green and clean gray wheels. There isn't any overly flashy chrome or decals. And the interior is the same with just an upgraded steering wheel, shifter and pedals in an otherwise stock cabin. Oh, and it has a manual.
