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.

This KITT replica sold at auction for $32,500

UPDATE: This 1987 Pontiac Firebird Trans Am KITT replica officially sold for $32,500. Here's hoping the new owner has a blast throwin' it into Pursuit Mode. Let's get one thing straight right off the bat: This isn't a perfect KITT replica. The original KITT used in the Knight Rider TV series was based on a 1982 Pontiac Firebird Trans Am. The one you see above, which is currently for sale at auction site Bring A Trailer, is a 1987 model, and since it's a GTA edition, it has some extra body cladding that the smooth-sided television car lacked. That aside, most casual observers would probably never notice the difference, and even those who did (like us) are still likely to be impressed by the car's transformation. This KITT replica is powered by a 5.0-liter V8 engine mated to a four-speed automatic transmission. It ought to be fairly quick, though quite a bit shy of the fictional car's very fictional 300-mph top speed. We're not exactly Knight Rider experts, but some quick Google sleuthing suggests that the Knight Industries Two Thousand supposedly cost more than $11,000,000 to build in Hollywoodland. This one will surely command a significantly lower sum — as of this writing, it's been bid up to $18,000 with four days remaining on the auction. This content is hosted by a third party.

There are several videos of the car that detail its modifications inside and out, but suffice it to say it seems to be a well-sorted replica. Here's hoping its new owner keeps it well clear of other KARRs. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

'We're not a hedge fund': Porsche plans to curtail speculators and flippers

A sizable number of speculators view cars as an investment. Rare or unusual models are quickly snapped up and either parked for years or flipped for a profit. Cars from automakers like Porsche and Ferrari are more prone than others, and at least some people behind these models are getting a bit tired of it. While it's difficult to police what goes on after you sell a car, Porsche has some plans that might curtail the problem before it starts. Andreas Preuninger, the head of GT road-car development and the man behind the new 911 GT3, spoke to Car and Driver at a recent event. "I personally like to see my cars being used," he said. "That's what we build them for. They are just too good to be left to stand and collect dust." One recent example of this rampant speculation is the 911 R. While the special manual-only model sold for $185,950 when new, used versions were selling for nearly $1.3 million just months after it went on sale. While the car is a masterpiece and an instant classic, a good number will be parked and simply used as art and not the rolling testaments to the man/machine interface they were intended to be. The concern over valuations has become so fierce that some owners are upset that Porsche is offering the new 911 GT3 with a manual transmission, fearing that it may hurt the value of the 911 R. "When I said we're not a hedge fund, I'm talking to those people who are yelling at us for offering the manual transmission similar to the R," Preuninger said. "But if there are people wanting to buy cars like that, then as a company we should try to fulfill that, to meet that demand." It seems Porsche is keeping a close eye on who is flipping cars. Since there is often far more demand than supply with certain models, the German automaker has a name for every car before it's built. Buyers with bad reputations might not even make the wait list.
