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.

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.

Celebrate the summer solstice by building the Pontiac Solstice shooting brake GM never did

Happy summer solstice, everyone! To celebrate, we have a particularly unusual eBay find connected to the Pontiac Solstice sports car. A seller has leftover inventory of fiberglass hardtops designed to turn the Pontiac Solstice roadster into a shooting brake. The seller says they came from a since-closed Indiana company, and they're clearly inspired by another aftermarket part and even a GM concept that never saw the light of day. We'll start from the beginning: the stillborn Chevy Nomad concept. It was a concept that came out about the same time as the original Solstice concept, and it was clearly based on the same platform, featuring a small two-door body and a long nose. It also had unashamedly retro Nomad wagon design cues and cues from the original Corvette. The car never saw production, but clearly people were interested in having a wagon-like sports car. That brings us to the next bit of history with an aftermarket hardtop developed by German company EDAG. We saw a prototype in person, and the overall shape seemed to fit the car — and the wraparound window design certainly seemed Nomadic. Besides the unique look, the hardtop and its functional hatch made the Solstice roadster's miniscule cargo space far more usable. It doesn't appear many of the tops were sold, though. These tops on eBay look very similar to the EDAG tops, though it's not clear if they're a direct replica or something similar. Being that the parts are leftover inventory, the seller notes that some of the tops may be missing pieces for installation, so only those who are handy with bodywork and fasteners, or who are able to lean on someone who is, need apply. Even with some extra work, if you really want a Solstice shooting brake, this is likely easier and cheaper than commissioning a shop to custom-build a roof for your. If you're interested, check out the link. They're $499.99 apiece, and the seller will also provide a set of seals and gaskets for the top for an extra $125.
