New Tech

Mercedes-Benz has gotten a lot of press recently about AdBlue, the additive that makes its new BlueTec clean diesel SUVs and wagons so clean. I called up Larkin Hill, a PR rep at Mercedes, and asked her to explain to me what this AdBlue and BlueTec stuff was all about.

“Twenty years ago, 80% of Mercedes sales were diesel,” said Hill. “But they had a reputation for being loud, slow, and sooty. The BlueTec diesels are quiet, fast, and clean. You can stand behind one in a white linen suit and not get dirty.” This, she said, is due to AdBlue, an exhaust treatment fluid used in all the BlueTec diesels to neutralize nitrous oxide emissions.

In order for the Mercedes BlueTec diesels to meet the U.S. Bin 5 emissions standard, the company had to guarantee that the customer would put AdBlue into the exhaust system. “You get many, many, many warnings,” said Hill. “The car gives you twenty chances. It counts down the number of starts you have left.” When you’re out of AdBlue and the countdown reaches zero, you can’t start the car without adding another quart.

The reservoir is easy to find and easy to fill, though, as it’s located in the spare tire well in the back. And you can go 10,000 miles of normal driving without worry. Most people will have their M-B dealer top off the AdBlue tank during regular maintenance. For those who do a lot of towing or want peace of mind, BlueTec owners can buy and carry extra quarts. It’s available at 1500 outlets, like Pep Boys.

Right now, there are three 2009 vehicles with BlueTec clean diesel: the ML320, the GL320, and the R320. Hill said the company plans to release an E320 sedan with BlueTec and AdBlue later this year. And yes, she said, AdBlue is indeed blue.

Though motor vehicles had been around for some 20 years, the White House didn’t make the switch from horse-drawn carriages to horseless carriages until William Taft took office in 1909. According to the L.A. Times, Taft chose an electric vehicle built by the now-defunct Baker company for the first Presidential conveyance.

Fast forward 100 years to president-elect Barack Obama, who made the following promises in his “New Energy for America” speech in August:

Put 1 million Plug-In Hybrid cars — cars that can get up to 150 miles per gallon — on the road by 2015, cars that we will work to make sure are built here in America

Within one year of becoming President, the entire White House fleet will be converted to
plug‐ins as security permits

Half of all cars purchased by the federal government will be plug‐in hybrids or all‐electric
by 2012

Obama also wants to provide a $7,000 tax credit for consumers who purchase advanced-technology vehicles and unspecified tax credits for folks who go the DIY route (or hire a firm to do it for them) and convert their car to a PHEV or EV.

If you’ve been considering an alternative-fuel vehicle for your next car but were wondering where on earth to fill up, look no further than the U.S. Department of Energy. That’s right — the DoE has put together a handy web site where you can search for refueling stations for just about any kind of fuel except regular, ol’ gasoline:

• Biodiesel (B20 and above)
• Compressed Natural Gas
• Electric
• Ethanol (E85)
• Hydrogen
• Liquefied Natural Gas (LNG)
• Liquefied Petroleum Gas (Propane)

It should surprise no one that California leads the way in most types of alternative fuel stations. E85 is huge in the Midwest, which is another no-brainer, but biodiesel is big in Georgia and the Carolinas, which I did not know. Texas has hundreds of propane filling stations, as anyone who watches “King of the Hill” would probably guess.

There is a ton of information on the Alternative Fuels and Advanced Vehicles Data Center, and it will be a valuable resource as more alternative-fueled cars come to market in the next four years or so. Bookmark it now, folks, and tell all your friends who love green cars.

LiveEarth and Zimride have teamed up over on Facebook to make it easy for the carless to find a ride to the voting booth. Cleverly called Carpool to the Polls, Facebook users just need to push the big green button at the bottom of the screen that says, um, “Carpool to the Polls.” They’ve really make it simple, folks.

Just under that big green button is a gray button that will help you find your polling station. Next to the green button is another green button for arranging a carpool anywhere else for any old errand that needs to be run.

This election is important for a lot of reasons, but one of the biggies this cycle involves sustainable energy sources and alternative fuels. I’m not going to tell you who to vote for, but it wasn’t the Barack Obama crowds shouting, “Drill, baby, drill.” I’m just saying.

So if you need an extra kick in the pants to get to the polls, sign up for a carpool. It’s greener than driving yourself, and you’re more likely to fulfill your commitment as a voter if you know someone is waiting for you at the curb, honking her horn, to take you to the voting booth.

Portland, Oregon, gets a lot of credit for sustainability and forward thinking, but it’s not the only place looking to an EV-powered future. Oregon City, a suburb south of Portland, unveiled its new curbside charging station October 28 by plugging in a converted electric Fiat owned by resident Mark Mongillo. The idea is to get a jump start, if you will, on the infrastructure required for the EVs and plug-in hybrids that manufacturers are promising for the near-ish future.

The charging station, which was built by Shorepower Technologies of Portland, is one of four that have been installed in the region by Portland General Electric. It can charge up to four electric cars at once using 120-volt plugs, like what we have in our homes. At that rate, it would take about four hours for a full battery charge. Most people parking curbside would likely “top off” their batteries while shopping or sipping coffee.

After the unveiling of the seven-foot-tall station, Mongillo plugged in his Fiamp to charge. Nothing happened. Nothing noticeable, anyway. The crowd seemed to expect noise or a light to turn on or something, but plugging in an EV isn’t that showy. Mongillo said, “That’s it. It’s working,” and the small crowd applauded.

Details on the Shorepower stations:

• 7 feet, 8 inches tall; stainless steel
• Powered by 100% renewable energy from PGE
• $2,500 for the four-outlet unit, not including installation
• Four 120-volt outlets; full charge in about 4 hours
• Charging is free (so far)

Legendary design firm Pininfarina has brought its own little EV to the Paris auto show this year, the B Zero. Actually, the model name is written B0, but the company has helpfully let us know that it’s pronounced “B Zero.” Presumably, they don’t want us Americans running around calling it the “BO.”

The B0 will roll off the production line in late 2009 as a 2010 model, the Italian company says. The mass-produced car is a collaboration between Pininfarina and Bollore, who will provide the powerplant. The proprietary system will use batteries and supercapacitors to propel the B0 about 150 miles per charge, with a top speed of 80 mph.

If zero emissions and a high-tech lithium polymer battery aren’t enough to float your eco-warrior boat, the car also has solar panels on its roof and even a few on its tiny hood. Right now, the panels will be able to run “some of its equipment,” according to Pininfarina. I assume this means they provide enough power for creature comforts like the radio and maybe air conditioning.

After giving us coy pictures of front corners and rear decks of the design concept, GM says they will unveil the Chevy Volt in all its production-trim glory at the company’s 100th birthday party September 16. Preproduction models will be built in 2009, with sales of the real deal expected to begin in 2010.

GM chair Bob Lutz told Automotive News Europe that the production Volt will be the “next generation global compact architecture.” For those who don’t speak Auto Industry as a first language, that means the U.S. version of the Volt will use many of the same underpinnings as GM’s upcoming world-market offerings. For examples of this design, keep an eye out for the Opel Astra and Chevy Cruze at the Paris auto show this year.

Meanwhile, according to Motor Trend, GM and the EPA are debating whether the Volt is a hybrid or an electric vehicle. The outcome will decide how fuel-economy numbers will be calculated. The car has an electric motor with a combustion engine that acts as a range extender when the batteries run out.

GM wants the car to pass the EPA’s tests using the electric motor 85% of the time, which would give it a rating of 100 mpg or more. The EPA wants the Volt to pass the tests with its batteries near full charge at the end, which would require the gasoline-powered engine to run most of the time. This calculation would drop the fuel economy to about 48 mpg. When fuel economy is your sales tool, a Prius-like 48 mpg might hurt sales of the $40,000-plus Volt.

The Alternative Energy and Transportation Expo will roll into Santa Monica for the third straight year September 26-27, at the Santa Monica Civic Auditorium. For the first time ever, the show will also set up camp in Texas, at the Austin Energy Alt Car Expo inside the Palmer Events Center October 17-18. Both events are free, free, free.

If you’re new to alternative-energy-powered vehicles, these events would be a good place to start. More than 150 exhibits will detail different fuels, such as hydrogen, hybrids, ethanol, electricity — both AC and DC — and even natural gas and propane. Experts will be on hand to answer any questions you may have, whether you’re an SUV driver thinking about driving greener or an engineer who converted his Porsche 914 to an AC motor.

Perhaps the most useful part of the expo is the Ride and Drive lot, where visitors can experience alternative fuels first-hand and evaluate their pluses and minuses from the driver’s (or passenger’s) seat. Seminars and panel discussions will be held during both weekends, featuring authors who’ve analyzed the future of the auto industry and movers and shakers from within the industry itself.

At a press event in Portland, Oregon, Dan Kapp, Ford’s director of powertrain research, said that the company has plans to become the number-one hybrid  producer in the country next year. By adding hybrid versions of the Ford Fusion and Mercury Milan to the Ford Escape and Mercury Mariner hybrids already on the market, Ford will double the number of its hybrids on the road.

Kapp laid out Ford’s long-term strategy, from today to 2050. The company plans to migrate its advanced fuel-saving technologies, like hybrid systems and the new EcoBoost engine, across the product line by 2012, so at least a few Ford, Lincoln, and Mercury vehicles will get a little better gas mileage. By 2020, Kapp said Ford will fully implement current technology and begin to delve into more gasoline-electric hybrids, plug-in hybrids, and more. After that, the plan is to roll out hydrogen fuel-cell cars, biofuel-powered vehicles, and whatever other new technologies have developed by then.

Kapp was eager to point out the advantages of Ford’s new EcoBoost engine, which uses gasoline direct injection and turbocharging to raise fuel efficiency by as much as 20% and lower tailpipe emissions by as much as 15%. The physically smaller engine will be able to deliver the same or greater power as traditional Ford engines, and will be available first in the 2009 Lincoln MKS sedan.

Kapp pointed out that while Ford was not pursuing hydrogen-powered cars as quickly as Honda, nor was it chasing Chevy’s PHEV Volt with any conviction, it does have the first driveable hydrogen fuel-cell PHEV in the Edge HySeries. The fleet of 30 cars is still very much in the test stage, and Kapp noted that hydrogen fuel has “monumental infrastructure problems.”

When fielding questions about bringing clean diesel cars from Europe (answer: not any time soon), a fellow journalist mentioned that he ran his diesel-powered Ford truck on B99 every summer. Kapp nearly choked on his coffee when he heard that one of his trucks was being powered by 99% biodiesel a few months out of the year. I was surprised that he was surprised — he was in eco-conscious Portland, after all.

Last week, the Internets were abuzz with the marketing hype of Fosh Automotive, which promised to unveil an EV with self-regenerating batteries and an unlimited range. I emailed the company and was told to cool my jets — all would be revealed on Monday, August 18, but it had something to do with “solar like” panels and regenerative braking.

Monday came, and the curtains on the Web site stayed closed. It seems that Fosh has had some television interest, so they delayed the unveiling of this perpetual motion machine they’re calling the EVT-3 until next Monday, August 25. And Fosh’s predicted price of $25,000 is out the window, too. Estimated MSRP of the EVT-3 is over $50,000 now.

There are forums on the site, and posters seem none too happy to be shunned for television cameras. Post headings include “Why Not Show the Demo Video Now?” and “Ok good joke now where is the real car”. The FAQ says the on-sale date is November 28, 2008, but we probably shouldn’t hold our breath.

If the EVT-3 works as promised, it could be revolutionary. But Fosh’s false start isn’t inspiring confidence so far.

I don’t mean GM has found a way to turn corporate bluster into a fuel source, though that would ease the burden of the price of gasoline. A while back, the Department of Energy issued a challenge to automakers. It asked them to improve fuel economy by 10% using nothing but wasted exhaust heat to help power the vehicle.

GM, with BMW close on its heels, has developed a thermoelectric generator that could create enough electricity to augment or replace the usual alternator in a gasoline-powered car. Thermoelectric devices can use temperature differences to create electricity. When one side of the generator is heated, electrons move to the cooler side. The movement creates a current, which is collected by electrodes and converted to electricity.

The GM prototype is set to be tested in a Chevy Suburban next year, where a 10% fuel economy boost would mean a 1-mpg improvement. In a small car like the Chevy Aveo (the Suburban’s exact opposite), the boost could be enough to put its combined economy over 30 mpg. BMW and its research partner Ohio State University will run tests of its prototype next year, too.

Nissan has commited itself to its Green Program 2010, and it keeps making strides toward meeting its goals. This week, it previewed its EV and hybrid technologies, though not any final designs for the cars these powertrains will power.

The electric vehicle will be based on an array of lithium-ion batteries installed under the floor to allow for maxium passenger and cargo space. Though no one outside the company knows what the EV might look like when it hits the market in 2010, it won’t look like anything Nissan currently offers, according to the company.

The hybrid will carry Nissan’s own, recently developed technology instead of the hybrid tech it’s been leasing from Toyota to power the Altima. The HEV will have regenerative braking and power assist like most hybrids on the road right now. The difference is in its parallel powertrain, which has two clutches to improve fuel efficiency, or so Nissan says.

Lotus Engineering, which I imagine looks like Q’s lab in the James Bond films, has found a solution to the problem of nearly silent electric motors: the Safe & Sound system. The Toyota Prius demonstration car has a speaker attached at the front of the car next to the radiator that emits a “realistic engine sound,” according to the company.

Earlier this year, groups like the National Federation of the Blind pointed out that blind people and their seeing-eye dogs rely on the sound of approaching cars to determine the safety of crossing the street. This spring, a boy on a bike was hit by a Prius, an accident his mother blamed on the silent electric motor (never mind that the car is not equipped with invisibility, like Wonder Woman’s jet). In reaction, people have been searching for a way to make quiet cars safer for pedestrians. One potential solution was the Vibering concept, which would sense hybrid and electric motors and tell the wearer when one is nearby.

Lotus’s system was ironically born from its noise-dampening technologies. Safe & Sound synthesizes the engine sound and varies it depending on speed so people waiting at a crosswalk or walking across a parking lot can hear the approaching vehicle. If it’s a hybrid, and it goes fast enough to engage the gasoline engine, the system automatically shuts off. Also, once the car passes, the sound is no longer heard.

Toyota’s researchers in Japan are working on using zinc air batteries for powering EVs. That’s right — batteries that create electricity out of thin air.

When oxygen from the air around us is introduced into a battery cell, it reacts with a zinc electrode to create electricity. The materials to build these batteries are cheap, and they have high energy density. So why aren’t these things powering your Mini already? Because not even a Mini is small enough to be powered by zinc air batteries. Right now, the most common use for zinc air is in hearing aids.

Despite the small size, Toyota hopes that the move from lead-acid and even lithium-ion batteries to zinc-air will blow open the doors of the EV market, providing the range and speed consumers want from a daily driver. There is a lot of possibility here — it wasn’t that long ago that li-ion batteries were only found in cell phones and laptops, not 100+ mph supercars like the Tesla Roadster.

Nissan announced that a new device called the ECO Pedal will be available on some of its 2009 models. The pedal will let the driver know that he may be using more fuel than necessary by pushing back on his foot a little. There’s also a little green “ECO” light in the dash to help you learn to use fuel wisely rather than wastefully.

Nissan says the ECO Pedal can earn a driver as much as 5-10% better fuel economy. They didn’t say which models will receive the new technology, or even which countries might get it.

In the meantime, U.S. car buyers can count on the Nissan Altima hybrid for 2009, which was named one of the top 10 green cars by Kelly Blue Book. The company just announced pricing for the hybrid at $26,650, and the EPA rated it at 35 city/33 highway.

Automakers have dreamed up a new all-green event to coincide with the wildly popular Woodward Dream Cruise. They call it NextCruise, and it will debut in Pleasant Ridge, Michigan, with a public preview Friday, August 15 and activities Saturday, August 16.

Nine automakers have signed up — General Motors, Ford, Chrysler, Toyota, Nissan, BMW, Mercedes-Benz, Audi, and Volkswagen — plus Bridgestone and the the IndyCar and American Le Mans racing series. All the participants aim to prove that green technology is clean, comfy, and cruise-worthy with displays and free 15-minute test drives.

Hybrids and clean diesels will make up the bulk of the event, in contrast to the cars rolling along Woodward Avenue at the14th annual Woodward Dream Cruise. Classic and muscle cars both pristine and hot-rodded will cruise from Ferndale, Michigan, to Pontiac in one of the largest vintage car cruises in the country. If anybody needs to be convinced of the fun to be had in low-emissions vehicles, it’s these guys.

Say you take the plunge and buy an electric vehicle, be it a neighborhood EV like the Zap Xebra or a supercar like the Tesla Roadster. You tool around all day, and you plug your car in at night to recharge. It only takes a couple hours to fully top up the batteries, though, even when they’re nearly depleted. Soon, you and your electric car can put those idle cycles to work while you sleep.

The Rocky Mountain Institute has published its first “Solutions” journal, which is available as a PDF. In it, they discuss the research conducted by RMI on vehicle-to-grid technology. Electric cars, with their built-in, onboard electricity storage devices (batteries, to you and me) can smooth out the power flow and provide emergency backup power:

The real benefit of electric vehicles is that they bring a new level of stability and control to the grid—including giving power back when it’s needed most (in blackouts or at times of peak demand). By some estimates, a battery-electric vehicle, with about 40 kilowatt-hours of usable energy, could power an entire residential block for over an hour if necessary.

During the 17 years that RMI conducted its V2G research, the grid in the U.S. became robust enough to handle this kind of power exchange. But RMI went further and imagined what they call a “smart grid” that can communicate with homeowners about, say, when electricity is in high demand and therefore more expensive.

There are also serious benefits, both economic and ecological, to getting more solar and wind power onto a smart grid — the reduction in carbon dioxide emissions alone would be significant. To see how all this plays out in the real world, keep an eye on the pilot project in Boulder, Colorado.
