This Auto Aerobics car art ties our brains in knots like pretzels

We like cars, and we like art. Naturally, Chris Labrooy's Auto Aerobics series - computer-generated images of some seriously contorted 1968 Pontiac Bonnevilles floating in mid-air - instantly clicked with us. If the Pontiacs weren't floating or hollow, we could be fooled into believing the image is real. But where's the fun in that?
Check out the gallery we included of Labrooy's Bonneville art, and feel free too head over to his website for some Formula One humor.

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.

eBay Find of the Day: 1967 Pontiac GTO Monkeemobile

Say what you will about The Monkees, but the guys in the band had great taste in automobiles. Take the Monkeemobile, for example. Built off a 1967 Pontiac GTO Convertible, the custom featured genuinely interesting bodywork and some wild engine bolt-ons. If you're a fan of 1960s pop and yearn to relive the genre's glory days, eBay Motors may have what you need. A recreation of the 1967 Monkeemobile has showed up for auction. This particular replica was built by Dakota County Customs using an four-speed GTO, just like the original.
Built for the band's 45th anniversary and the final Monkees tour last year, this Monkeemobile is faithful down to every last detail. Unfortunately, the trumpet exhaust poking out of the front fender wells and the massive gold-flake blower are for show only. Seems fitting.
If you like what you see, this machine is up for bid in Richfield, Minnesota with two days left on the auctions. So far, bidding as whipped up to $60,000 with the reserve not met. Head over to eBay Motors to have a look.
