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.

Aficionauto sits down with The Hoff and KITT

The latest video from The Aficionauto is the perfect palate cleanser for Knight Rider fans after finding out that Justin Bieber is the voice of KITT in an upcoming film. Host Christopher Rutkowski says that the Knight Industries Two Thousand is one of the most requested vehicles to appear on the series and for good reason - Michael Knight's Pontiac Trans-Am is among the most famous cars to ever appear on television.
While the video isn't able to showcase one of the original KITTs from the series, it does get star David Hasselhoff to drive his personal replica and talk about the lasting legacy of the show. The highlight here might be seeing The Hoff back behind the wheel in the open desert basically recreating Knight Rider's opening sequence.
With all of its flashing lights and gizmos, you can probably make the argument that KITT is pretty cheesy, and the show itself was never exactly a pillar of high-quality drama on television. Despite that, the series still provides a ton of good-natured fun, and The Hoff's continued enthusiasm for it is pretty infectious. Check out The Aficionauto video to take another ride with Knight Rider.

2020 Porsche 911 Speedster spied with an angry driver

Porsche gave us details and showed us a concept of the 911 Speedster at the Paris Motor Show. Today, we bring you spy shots of what appears to be the production version of that concept with a few changes on board. They're rather minimal modifications, but the Speedster's driver appears especially angry with our spy photographer as he extends his middle finger directly toward the camera. Sorry, not sorry, Mr. Test Driver. Public testing of pre-production cars always comes with photo risks, and Porsches tend to attract more attention than others. You'll notice what appears to be a Cayenne Coupe prototype we've previously spotted running around with the 911. The Speedster Concept we saw in Paris had epic retro mirrors and fuel cap on the front hood, but both those design touches are absent from this pre-production car. It's tougher to see, but we lost the vents in between the two humps, as well. Everything else appears to have made it to production-spec. We can't say we're surprised these concept car features probably won't show up on the production car, but it is a tad deflating. You'll notice the Speedster is based-off the 991.2 generation of 911 and not the new 992. Porsche did a similar thing when the 997 generation was coming to an end with a Speedster model paying tribute to that car's life. The chassis is said to utilize parts from the 911 GT3, and the wonderful naturally aspirated flat-six engine gets carried over from that car, too. Porsche didn't specify if power will be exactly the same as the GT3, but we'll be expecting about 500 horsepower and a 9,000 rpm redline. We were told the six-speed manual would be offered on the Speedster in Paris, too. Let's just say that we strongly approve of that combination. Production will be limited to only 1,948 cars and begin in the first half of this year. We'll expect a reveal with a full spec breakdown soon, possibly for the upcoming Geneva Motor Show.
