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.

Rolling Out The Solar Carpet

The flexible solar roll by Brunton has been around for a little bit; but it's simply too cool not to mention for those who have never seen it.

The beauty of this product is that it's waterproof, light, and rugged enough to take with you anywhere. It has assisted climbers on summit expeditions, kayakers on remote islands, and people (like me) who have a flat tire, no spare, and a dead cell phone. You can even use their $500 model to charge your car battery. That my friends is a benefit that in the worst of times is priceless. This large roll will also power you laptop or satellite phone in the Outback.

Solar Rolls come in two other sizes for smaller appliances, The Solar Roll 9 (12" x 40", 9 watts output, $349) for smaller items, such as digital and video cameras, and the Solar Roll 4.5 (12" x 22", 4.5 watts output, $199) for charging the smallest electronic devices, cell phones. All Solar Rolls have built-in reverse current protection.

So, the application possibilities are pretty endless. I'm a big fan of the thin-film revolution, simply because light-weight accessories for camping or circling the world are in hot demand, and I appreciate backup solutions that do not slow me down. I also like that you can lay this product out and attach it to most anything. As investment and research drives the efficiency of these panels up, we can expect even smaller backup energy sources to accompany us on nature's largest challenges.

KBB: high gas prices changing shopping habits in U.S.

Filed under: ,


While AAA says that Memorial Day motor vehicle travel won’t be affected by high gas prices, KBB has found that the “meh” attitude doesn’t transfer to consumer shopping behaviors. The main changes are that Americans are shopping less, eating in more and altering new vehicle-buying decisions. Actually, put all that in the future tense. KBB says that, “a majority of consumers plan to take steps to combat the hit to their wallets. According to the latest Kelley Blue Book Marketing Research study on gas price effects, half of new vehicle shoppers plan to purchase less retail items such as clothes and shoes, more than a third plan to eat out less often, and another third plan to buy less media entertainment items as long as gas prices continue to squeeze their wallets. Luxuries like a night out on the town, music sales, as well as movie ticket sales could all experience declines through the summer when gas prices are expected to top $4 a gallon” (emphasis added).

The details can be found in KBB’s press release after the jump, but the trick with all of these studies about consumer behavior is that it’s easy to tell a survey-taker that you’re going to change your ways, but then what happens when it’s Memorial Day and you want to go camping? Apparently, you just go. And shoppers have been more into hybrids for a while now, getting ready for $4 gas. $4, huh? It’s like some sort of alternate reality.

Latest Study Shows High Gas Prices Affecting Consumer Shopping Behavior

Consumers Alter New Vehicle-Buying Decisions, Shop and Eat Out Less Often Due to High Gas Prices

IRVINE, Calif., May 18 /PRNewswire/ — With gas prices reaching their highest level in recent history, $3.10 a gallon for regular unleaded, a majority of consumers plan to take steps to combat the hit to their wallets. According to the latest Kelley Blue Book Marketing Research study on gas price effects, half of new vehicle shoppers plan to purchase less retail items such as clothes and shoes, more than a third plan to eat out less often, and another third plan to buy less media entertainment items as long as gas prices continue to squeeze their wallets. Luxuries like a night out on the town, music sales, as well as movie ticket sales could all experience declines through the summer when gas prices are expected to top $4 a gallon.

When it comes to shopping for their next new vehicle, nearly six out of 10 new-vehicle shoppers (59 percent) say that the upward trend in gas prices has either changed their mind about the vehicle they are considering buying or are strongly considering the purchase of a vehicle they normally would not have considered

With the quick rise in gas prices and expectations for even higher prices heading into the summer, only a small few are not yet fazed, while others plan to do more research before they buy a new vehicle. Twenty-seven percent of in-market new-vehicle shoppers said that current gas prices are having little or no effect on the vehicle they are planning to purchase. Fourteen percent of vehicle shoppers say higher prices did not have an effect on their decisions because they were already planning to buy a fuel-efficient vehicle. Forty-one percent of those participating in the survey say that if gas prices rise an additional 25 cents above current levels, they too will start researching vehicles they would not normally have considered.

“These results make it clear that American consumers are more than willing to make changes in their buying decisions due to rising gas prices,” said Jack R. Nerad, executive editorial director and executive market analyst at Kelley Blue Book. “This will have negative implications for the domestic manufacturers as they are perceived as building low mileage vehicles and will therefore be an issue the new ownership of Chrysler will have to deal with immediately to assist in the turn-around of that company.”

Flack Attack: Corporations Prepare to “Target Green”

Article Photo by Worldchanging local blogger, Brian Smith: On May 5, 2007, PR Week (a national trade journal) held an ambitious event “Target Green: Making Sustainability Work.” The stated goal of the conference was to highlight how corporations are “making meaningful changes that benefit the company, and the planet, and how PR and marketing play a crucial role.” Spokespeople at the conference came from some of the largest corporations on Earth: GE, Dow Chemical, Dell, Sun Microsystems, Siemens, UTC, Phillips, and even, ExxonMobil. Up on stage left and right, jumbotron screens flashed the names of the sponsors: big media, food companies, and international marketing firms. Next, single words flash in Orwellian repetition in white letters on green background: “Authenticity,” “Credibility,” “Responsibility,” “Sustainability.” The timing of such an event was clear. Green marketing has become the 21st century’s version of “Customer Knows Best.” And without a working knowledge of Green marketing, corporate PR teams would fall hopelessly behind the curve. Massive piles of investor cash are headed in the direction of Green products and companies. To catch the wave, every company must find a way to describe what they do as environmental. And to a certain extent, we did that. How? By… (more)

AABC discussion on automotive lithium battery requirements

Filed under: ,


The hybrid battery test lab at the GM Technical Center

Earlier this week Long Beach was host to the Advanced Automotive Battery and Ultracapacitor Conference (AABC) which featured a panel discussion on what it will take to bring lithium ion battery technology to the mass market. Included on the panel were GM’s Joe LoGrasso and Mark Verbrugge and Ford’s Ted Miller. All acknowledged that lithium batteries are inevitable, and that it’s just a matter of ironing out the details over the next couple of years. Of course many of those details aren’t exactly trivial, but they can be overcome.

Nickel metal hydride batteries are known quantity and thermal and charging management are fairly straightforward. The biggest problem is limited energy/power density when compared to lithium batteries. There is also a decent amount production capacity for large scale NiMH batteries although nickel prices have been on the rise of late. To date no one has produced large quantities of automotive-sized lithium cells. Tesla is building their battery packs up from 6,800+ laptop cells which means each pack will have almost 14,000 interconnects any of which could be defective or fail. The big manufacturers want to use larger cells to cut the number of interconnects and reduce the number of potential failure points.

Anther area that battery manufacturers and car companies are addressing is standardizing interfaces between the vehicles and battery controls as well as the way battery life and charge history is calculated for warranty coverage. Improved models of the battery behavior are important to ensuring that the management software extracts the maximum output and life out of the battery. There’s more at GreenCarCongress.
