Gas 2.0

After the new Executive Order last week requiring every Federal Agency to accurately account for their greenhouse gas emissions—and then sharply reduce them 30% by 2020 [previous story]—the Navy has doubled down in their response.

Already the Navy uses 17% renewable energy (about like Iowa and even better than California), but they plan on achieving a faster reduction and a much tougher goal that that decreed by the president: fifty percent—some of which will be achieved by 2015. Or as US Secretary of the Navy Ray Mabus put it: “Our Navy and Marine Corps has never backed away from a challenge.” [ed. note: THAT makes me so damn patriotic I have no words. Anybody who says greenies aren't patriotic can go suck it.]

Many of you have heard of Ricardo, a company that has a rich history in Motorsports. However, most of you probably haven’t heard of Recaptured Energy Technologies (RET), until now. The company has just announced a partnership with Ricardo to develop and produce “Green Solutions” to the fuel and emissions problems that plague fleet, commercial and transit vehicle operators.

RET’s basic technology is this: they have a retrofitable hydraulic propulsion system for large vehicles that stores energy in hydraulic cylinders with compressed gas. The vehicle, such as a city bus, then uses that stored energy to give it a boost when starting up. The technology is known as RPS, or Retrofitable Propulsion System, and reduces fuel use by 25 percent and emissions by 25 percent. But before you finish mumbling about how improved fuel economy doesn’t eliminate our dependence on fossil-fuel based energy, this system can improve the fuel and emissions of vehicles using all forms of fuel including ethanol, biodiesel, compressed natural gas, propane and more.

“We like to say that the vehicle is indifferent and fuel agnostic,” said Sam Jones, President of Recaptured Energy Technologies. Read the rest of this entry »

A group of University of Kansas students have rigged up a 1974 Volkswagen Super Beetle to run on a mix of biodiesel and battery power.

The team, calling themselves the Ecohawks, claim the quirky hybrid is capable of getting 50 MPG from a series of 10 lead-acid batteries and a biodiesel generator.

Performance-wise, although quite cool looking in a retro kind of way, the car isn’t exactly what you’d call a speedster, topping out as it does at a leisurely 30 mph.

That doesn’t seem to bother team-leader Prof. Chris Depcik though, who told reporters, “We have driven it around and reached approximately 30 mph, but this was more of a proof-of-concept drive without pushing the boundaries. We are currently getting the vehicle into road-ready shape to be driven safely in order to determine these values.” (More pics after the jump).

Today, Coskata Inc. unveiled their semi-commercial flex ethanol factory in Madison, PA. This factory will serve as the first commercially viable flex ethanol factory, which produces ethanol from a variety of feedstocks other than just grain—which is an important step to satisfy food vs. fuel issues and start moving past ethanol from corn.

According to Coskata, their process uses less than half the water needed to make a gallon of gas, while producing seven times the energy of the fossil fuel used in the process.

Take a look at the first picture of what Honda hopes will become the future of motorbikes. The Honda EV-Cub is an all-electric version of the company’s top selling Super-Cub, and could be on sale as early as next year.

Details are scant about the new machine, but sources say that the retro looking EV-Cub will be two-wheel drive to offer riders more stability and traction.

A fuel-cell-powered aircraft set a world record by staying aloft for a whopping 23 hours and 17 minutes on just a single load.

In fact, the unmanned aircraft broke the previous record by double. Of course, the plane was built by the Naval Research Laboratory and not by students from the University of Michigan. Still, those students kept their plane in air for over 10 hours–impressive!

Of course their plane was only $2,500. I am guessing the Navy-built one cost us a whole lot more.

An analysis done by Biofuels Digest has come to the very surprising conclusion that an electric car will produce 30% more carbon dioxide emissions over its lifetime than a car powered by E85 corn ethanol. Not only that, the study also found that the same electric car will produce 21% more carbon dioxide than even a gasoline powered car.

These claims assume that 100% of the electricity for the EV comes from coal-fired power plants and that a comparable car would get 35 mpg—both of which seem like unrealistic assumptions. So I dug around the internet today to try and come up with more realistic numbers.

Cow poop is a leading contributor of nitrous oxide and ammonia into the atmosphere, adding heartily to global warming. Cars, as we all know, provide their own fair share of noxious fumes to the environment. But a British team of engineers and racers is working on a way to kill two birds with one stone (metaphorically of course) by developing a race car that can run on cow poop.

Realizing that most technology found in our daily drivers was often first developed for the race track, Oaktec has announced plans to develop a manure-powered rally car, giving all new meaning to the phrase “This car runs like crap!” [ed. note: cow farts and burps contribute far more GHGs than poop, but hey, you gotta start somewhere]

Attendees at a recent alternative fuels gathering in Washington are reporting that US Secretary of Energy Steven Chu remarked, “If it were up to me, I would put every cent into electric cars,” when referring to the way stimulus dollars should be distributed. With a focus on alternative and renewable fuels, the group was obviously shocked at the concept.

If this statement is being represented accurately, it would not only put Chu directly at odds with Obama administration policy, it would mean that he doesn’t really believe in how his department is distributing their $36.7 billion dollar slice of stimulus funds. The statement would also contradict Chu’s previous stances on biofuels development. Comment from DOE was not immediately available, but I’ve got a request in to confirm or deny the statement as accurate. I’ll update as soon as I hear word.

Update 8:00 PM Pacific Time 10/13/2009: DOE’s Director of Public Affairs, Dan Leistikow, responded to my request from earlier today in an email, saying “I can’t verify the quote the blogger is using from an undisclosed source at an undisclosed meeting, which is at best wildly out of context.” He also added, “Anyone who has spent five minutes listening to Secretary Chu also knows he is one of the country’s staunchest advocates for pursuing a broad portfolio of clean energy research, and has warned against investing all our resources in a single technology to the exclusion of all others.” Read the rest of this entry »

Drag racing is probably one of the most wasteful-yet-exciting forms of motorsports around. For those three and a half seconds, Top Fuel cars can go as fast as 300 mph and burn 5-6 gallons of high-octane fuel in 1/4 mile, the equivalent of using 20 gallons per mile [ed. note: not if they're electric drag racers!].

But not all drag racing with liquid fuels is so wasteful. The videos below show a hydrogen peroxide-powered drag bike rocketing off the start line. After seeing it, I did just a little digging and uncovered a whole lot more to hydrogen peroxide power than I ever imagined.

Legendary Italian carmaker, Pininfarina, may yet have some surprises up its sleeves. Even with recent financial difficulties, Pininfarina’s CEO, Silvio Pietro Angori, told Italian newspaper, Il Sole 24, that the company’s Bluecar electric car venture with french investor Vincent Bollore is not simply a concept car and still on track for a 2011 market debut.

While Electric Vehicles (EVs) gear up to hit Main Street next year, EVs are already rolling through Wall Street.

An example is the recent (and successful) initial public offering (IPO) by the American battery maker A123 (AONE). A123 provides lithium-based batteries for EVs, and through its IPO, has now provided the finance community with one of the first mainstream opportunities to invest in a pure EV play. The overwhelming response from the “Street” reflects tremendous market confidence in the future of the EV business. Read the rest of this entry »

They don’t know how it works, but it does.

A team of researchers at Georgia Tech has developed a new high-tech ceramic material that could make solid oxide fuel cells less costly and less finicky, and much more durable and efficient. The material is called Barium-Zirconium-Cerium-Yttrium-Ytterbuim Oxide. [Ed note: Say that three times fast and you get a gold star.] I don’t know if it’s any less of a tongue twister, but it’s known as BZCYYb for short.

Solid oxide fuel cells are of interest because they can generate energy without the need for an expensive catalyst such as platinum, which is typically used in hydrogen fuel cells. While nanotechnology is enabling the development of hydrogen fuel cells that use less platinum, with BZCYYb the prospects look good for ditching the precious metal entirely in favor of more sustainable technology—if solid oxide systems can be developed in a commercially viable form, that is.

BMW’s Simple concept–which kinda looks like a Stealth Bomber with training wheels–is a hybrid trike that gets around 120 mpg.

The Simple (which stands for Sustainable and Innovative Mobility Product for Low Energy consumption) does 60 mph in just under ten seconds and has a top speed of 125 mph. The car weighs just over 900 lbs and has a super low drag coefficient of 0.18. Read the rest of this entry »

Like the iMiEV electric car before it, climbing another steep Japanese mountain range, the Chevy Volt has just demonstrated that it can do the hard stuff. It can get you up a long steep mountain climb in the snow.

And like the Japanese iMiEV—which works for the Japanese Post Office—our own “Government Motors” electric vehicle might be initially sent to work for government agencies in this country (that buy 750,000 thousand vehicles a year), because President Obama signed an Executive Order last week that requires every Federal Agency to cut fuel use 30% over the next nine years.
