Chrysler group looks to Metaldyne low-emission exhaust manifolds for PZEV vehicles

Filed under:

Being cut from the Daimler family doesn’t mean Chrysler isn’t moving forward on their green auto initiatives. One announcement from the Chrysler Group this past week is that the company has chosen Metaldyne for a multi-year contract for “environmentally-friendly exhaust manifolds for future vehicle platforms.” It’s not a new li-ion battery contract or something earth-shaking, but it’s something.

The lower-emission manifolds are intended to help Chrysler vehicles meet PZEV (Partial Zero Emissions Vehicle) requirements in states that follow California’s emission standards. Metaldyne is a subsidary of Asahi Tec. By heating the catalytic converter quickly, exhaust gases mix faster in the manifold’s single-wall design. There is also “a secondary air system that injects ambient air back into the cylinder head during cold start conditions. The ability to mix the exhaust gases at a higher rate and the use of the air injection system reduces emissions when a driver starts his or her vehicle,” as Metaldyne puts it.

Magna Steyr working on LiIon storage system

Filed under: ,

It appears that Magna Steyr wants to expand their horizons in the wake of losing the BMW X3 assembly business. At the Advanced Automotive Battery and Ultracapacitor Conference (AABC), Battery Systems Product Manager Peter Pichler announced that series production of Magna’s lithium ion battery packs would be in production in 2009. The initial packs will use cylindrical cells while packs with prismatic cells would enter production in 2010. The first packs for mild hybrids will be air-cooled but full hybrid packs will liquid cooled. So far Magna has used cells supplied by Saft but other cell manufacturers will also get a chance.

Shell’s “Eureka” extended commercial comes to DVD in WIRED

Filed under: , ,

There is a ridiculously small number of people who have had their lives transformed into a movie. There number of people who have seen their lives spun into a nine-minute corporate commercial is even smaller.
Billed as “A story inspired by real events,” the Shell Films commercial “Eureka” has been available for a while, but I hadn’t seen it until this month’s WIRED arrived. The issue is polybagged with a copy of the film on DVD. I figured I could spend nine minutes of my life I’ll never get back on the agitprop, and let AutoblogGreen readers know if it’s worth their time. It’s not.

The film isn’t poorly filmed or executed in any way – I’ve been to enough film festivals to know that it’s easy to make uninspired short films – it’s just not really fun to watch a well-lit press release. I’ll summarize the film – with spoilers – and also put the YouTube stream of the movie (the clip above is the trailer) in case you want to decide for yourself after the jump. You can also watch the film over on the Shell website.

[Source: Shell, WIRED, YouTube]”Eureka” is about Jaap van Ballegoolien, a shell engineer, and his troubled son (apparently, his trouble is that he stays out late and tries to call his father who works on the other side of the works thanks to Shell). We also meet a semi-ignorant, idealistic reporter (look, she wears dress shoes to talk to a meeting with our roughneck Shell oil engineer/hero. How darling). Thanks to her suggestion that he take time away from the problem – trying to squeeze every last bit of oil from already-standing oil platforms – he returns home to Amsterdam and takes his son out for a burger and milkshake. Bingo presto, an idea is born. Or should I say “eureka.”

The film tells us that the “Snake Well” as invented by Jaap van Ballegoolien, and his team, is now being used in Shell’s Champion West Oil Field in Brunei. The inspiring message from this discovery: keep using your oil, we’ll find ways to drill it. In the film, van Ballegoolien says, “I thought of calling it [the Snake Well] the ‘bendy-straw’ drill. The beauty of this technology is that it means fewer wells, which means less disruption and less waste. Prolonging the life of oil fields across the world, whilst we continue developing alternative energy sources.” Where’s the DVD of that process? You’d think by making $4.37 billion or so in profit per quarter, there should be money in the budget, no?

Weekend Web Review: How Can I Recycle This?

Most of us have a fairly narrow view of what it means to recycle: we gather materials (aluminum, paper, glass, plastic) in blue bins and either leave them on the curb for a pick-up service, or take them to a drop-off point. British site How Do I Recycle This? takes a much broader view of the concept — essentially merging reuse and recycling — and provides a forum where users can submit there own ideas for getting more use out of items that most of us would throw away without a second thought.

If you don't live in Great Britan, don't let the UK URL, or location of publishers Louisa Parrry and John Leach, put you off: there's very little in this blog's many posts that applies only to Brits or Europeans. Furthermore, don't expect the tried and true reuse projects that many of us did when we were kids (i.e., making bird feeders out of milk cartons) — the range of materials and recycling/reuse ideas at How Do I Recycle This? is quite eclectic. Some of the more unusual items:

Parry and Leach post new items on Mondays, Wednesdays and Fridays, and users are welcome to submit suggestions (whether they've successfully reused or recycled them item themselves or not).

The most impressive aspect of the site is its focus on harnessing the ideas of its users: Parry and Leach do offer their own suggestions when they have them, but every post is geared towards gathering ideas from readers. This is Green Web 2.0 in a pretty pure form: anyone can contribute their "authority" on the subject. While some items require an explanation of regulations for safe disposal (i.e. CFLs), the majority of the "trash" listed on the site encourages a free and creative exploration reuse possibilities.

"How Do I Recycle This?" has been online since April, 2006, and appears to have recently grown in its offerings — as recently as April, most posts appeared at the end of the month. I have no doubt, though, that the site's readership will keep it in "junk" that can find a better place than the trash can or landfill. The publishers have also launched a companion site, Compost This, that's a bit more directive, but still very useful.

Clean Power Technologies developing a steam hybrid system

Filed under: ,


British company Clean Power Technologies is working on a novel new type of hybrid powertrain. They are taking advantage of the fact in an internal combustion engine upwards of thirty-five percent of the energy in the fuel goes out the exhaust pipe in the form of heat in the exhaust gases and a similar amount is dissipated by the cooling system. Clean Power wants to recapture that lost heat energy and store it in the form of steam.

So far that seems like a good idea, the problem is that in the confined space of a car utilizing steam can be problematic. The hot exhaust and cooling system are used to produce the steam which is stored in an accumulator. Power plants use steam to drive turbines and generators. A car would be unlikely to generate enough steam flow to keep a turbine running. Instead Clean Power is using a pair of Mazda RX-8s to develop their system. They have modified the Wankel rotary so that one rotor runs normally on gasoline while the other is driven by steam.

Over the next year they will be modifying the RX-8s and testing them. It will be interesting to see if the steam system can add enough power to the drivetrain to overcome the extra weight or whether it will be better than just a smaller displacement engine of similar efficiency. We’ll be keeping an eye on this unique new approach.

Iowa State University: U.S. near tipping point in corn-based ethanol

Filed under:

This month, researchers at Iowa State University released a study that projected future domestic ethanol production rates and “its impacts on planted acreage, crop prices, livestock production and prices, trade, and retail food costs.” That’s a tall order, and the results are none too sweet for corn-based ethanol promoters.

ISU found that “expanded U.S. ethanol production will cause long-run crop prices to increase. In response to higher feed costs, livestock farmgate prices will increase enough to cover the feed cost increases. Retail meat, egg, and dairy prices will also increase.” If ethanol demand is such that U.S. corn-based ethanol production grows to over 30 billion gallons a year, then U.S. food prices will increase by at least 1.1 percent as a result.

Perhaps most alarmingly, “cellulosic ethanol from switchgrass and biodiesel from soybeans do not become economically viable in the Corn Belt under any of the scenarios. This is so because high energy costs that increase the prices of biodiesel and switchgrass ethanol also increase the price of corn-based ethanol. So long as producers can choose between soybeans for biodiesel, switchgrass for ethanol, and corn for ethanol, they will choose to grow corn.”

The National Chicken Council looked at the report and came away with the headline: “U.S. Near Tipping Point in Corn-Based Ethanol.” You can read their thoughts after the break, and the study itself is available at ISU’s website.

Study: U.S. Near Tipping Point in Corn-Based Ethanol

A major new study finds the United States is near the tipping point when it comes to corn-based ethanol production.

The study, conducted by the Center for Agricultural and Rural Development at Iowa State University (ISU), finds that U.S. retail food prices already have increased $14 billion annually. They could climb $20 billion annually if crude oil prices reach $65 to $70 per barrel and U.S. corn prices reach $4.42 per bushel, compared to $2 per bushel in mid-August 2006. At that crude oil price range, U.S. ethanol production could reach 30 billion gallons by 2012, consuming more than half of U.S. corn, wheat and coarse grains, and triggering higher meat and poultry prices for consumers, reduced meat and poultry production, and significant reductions in grain and meat exports.

“This study clearly shows that we are reaching a tipping point, and that over-reliance on corn-based ethanol to meet mandates would further drive up retail food prices, reduce domestic meat and poultry production, and erode our meat and grain export markets,” said J. Patrick Boyle, president and chief executive officer of the American Meat Institute (AMI), one of the study sponsors.

The study indicates corn yield gains would be sufficient to moderate grain price increases if corn-based ethanol production peaks at 14 billion to 15 billion gallons annually by 2010 (10 percent of U.S. gasoline consumption), when existing ethanol plants and those already under construction come online. Under that scenario, corn prices peak at $3.43 per bushel in 2009 before leveling off at $3.16 per bushel by 2016.

As for cellulosic ethanol, the study finds that a subsidy of $270 per acre would be needed to encourage producers to convert to switchgrass on land capable of growing corn.

The study also finds that if the United States was producing 14.7 billion gallons of ethanol and experienced yield losses similar to what occurred during the 1988 drought, corn and soybean prices would increase to $4.75 and $8.50 per bushel, respectively, triggering a 60 percent decline in U.S. corn exports and corn stocks, and a 50 percent increase in feeding of U.S. wheat to livestock.

“In addition to diversifying our energy sources, biofuels offer U.S. agriculture a way to diversify its markets,” according to Kendell Keith, president, National Grain and Feed Association (NGFA). “But this study clearly shows any supply disruptions in the United States or other major foreign grain-producing countries could trigger major ripple effects on multiple users of grain in the short run, including herd liquidations, higher grain processing costs and steep reductions in U.S. grain and meat exports.”

The study projects the following if season-average corn prices over a 10- year period ending in 2016 increased to $4.42 per bushel (based upon $65-$70 per-barrel crude oil), compared to $2-per-bushel corn:

— Pork: Production declines 9.2 percent. Production costs increase 6.8 percent. Retail prices increase 8.4 percent. Exports decline 21 percent, reversing 15 consecutive years of pork export growth.

— Poultry: Broiler exports down 15 percent. Turkey exports fall 6 percent. Wholesale broiler prices increase 15 percent. Retail prices increase 5 percent. Domestic consumption down 4 percent.

— Beef: Retail prices increase 4 percent. Production down 1.6 percent. Significantly, the study projects prices for distillers dried grains with solubles will closely track corn, meaning price increases are nearly as significant for beef and dairy as for hogs and poultry.

— Corn: U.S. planted acreage increases 44 percent to 112.5 million acres. Corn exports decline 63 percent.

— Soybeans: Planted acres decrease from 75 million in 2006 to 57.3 million acres. Exports drop 33 percent.

— Wheat: Plantings decline significantly to 42 million acres. Exports decline to 483 million bushels.

The study also notes acres currently idled in the Conservation Reserve Program (CRP) could play a useful role in “alleviat(ing) some of the financial stress on livestock producers” (during the early years of rapid ethanol growth), as well as mitigate short-term disruptions in grain supplies.

Study funders include AMI, Grocery Manufacturers/Food Products Association, National Cattlemen’s Beef Association, National Chicken Council, NGFA, National Pork Producers Council and National Turkey Federation.
