Rob Elam, biodiesel buff, answers questions

Rob Elam. What work do you do? I'm a cofounder of Propel Fuels, a biodiesel services and distribution firm. Biodiesel is a vegetable-oil based fuel for diesel engines. Using it significantly reduces greenhouse-gas and particulate-matter emissions. What does your organization do? Our mission is simple: fill tanks with biodiesel. We're approaching this in three ways: 1) helping retail station owners get biodiesel pumps up and running, 2) providing consulting services for businesses to help ease them into biodiesel use, and 3) offering design/build services on the production side. There's a lot of confusion and bad information when it comes to …

Umbra on true hybrids

Dear Umbra, I read the New York Times article that reported auto manufacturers are using hybrid technology to boost power rather than improve mileage. It specifically mentioned the Honda Accord, claiming that the mileage difference between the six-cylinder and the hybrid is minimal. What are the facts here? Is there a hybrid that really, actually, no-foolin'-around, gives really good mileage, represents a significant improvement over the regular version, is reasonably safe, and still drives well enough that one may venture onto the interstate without undue fear? JimKalamazoo, Mich. Dearest Jim, I'm glad you wrote. That article stirred some people up, …

Dense and Densibility

Densest U.S. cities aren't the ones you think Advocates of energy-saving urban density usually laud the towering buildings and subways of Manhattan, as contrasted with the car-heavy suburban sprawl of, say, Los Angeles. But the most dense city in the U.S., measured by people per square mile, is ... Los Angeles. In fact, despite its reputation for sprawl, the West contains 10 of the country's 15 most densely populated urban areas, among them San Francisco, Las Vegas, and San Jose. At work is not a miracle of urban planning but physical limitations: a pervasive lack of water, large mountain ranges, …

Prius-toric

Team achieves 110 mpg in Toyota Prius If you thought fuel efficiency was cool, wait 'til you meet ... Xtreme fuel efficiency! Rawk! Ahem. A team of five oddly obsessive middle-aged American men, seeking to break the unofficial mileage record set in Japan, recently drove a factory Toyota Prius 1,397 miles on one tank of gas, spending two days circling around one 15-mile stretch of highway near Pittsburgh, Penn. By the end they were tired and sweaty but exultant at achieving a mind-boggling 110 miles per gallon. The key was expert application of the "pulse and glide" hybrid-driving technique -- …

Hybrid Fidelity

Toyota plans 10 new hybrids, invites automakers to eco-summit Toyota is developing 10 new hybrid models and aims within the next few years to be selling 1 million of the gas-electric vehicles annually worldwide. That, says the company's U.S. head, Jim Press, will mean about 600,000 new Toyota hybrids each year on American roads, including hybrid versions of nearly every model it offers. The auto honcho pooh-poohed recent complaints that hybrid tech is being used to increase engine power instead of fuel economy, blaming that fact on automotive software and consumer driving habits. He predicts drivers will someday be able …

Meet the world’s first hybrid-cab driver

Like any self-respecting cabbie, Andrew Grant has a talent for small talk. But when the conversation turns to his prized 2004 Toyota Prius, things get a bit more animated. Andrew Grant. "Gave Cameron Diaz a lift once," he says matter-of-factly, leading me toward the Vancouver curb where the curvaceous car is parked. "Oh, yeah? What did she say?" "She said, 'This is nothing, I've got two.'" "What -- two hybrids?" He pauses just long enough to keep things respectable: "Yeah." Fame, as Andy Warhol once so eloquently opined, is a universal phenomenon, and Grant boasts his own rather lofty claim …

Gas-Muzzler

EPA holds back negative report on U.S. auto fuel efficiency According to a report not released Wednesday by the U.S. EPA, loopholes in U.S. fuel-economy standards let automakers produce cars and trucks much less fuel-efficient than models 20 years ago. On Tuesday, the same day the long-debated energy bill emerged from congressional negotiations, EPA opted to keep the report to itself for another week. An agency spokesflack says it's being reviewed for clarity and thoroughness, but some think the delay has a peculiar smell. Says the Sierra Club's Daniel Becker, "Something's fishy when the Bush administration delays a report showing …

Umbra on car disposal

Dear Umbra, My wife and I are making plans to purchase our first hybrid vehicle and need to properly dispose of our current car -- a 1989 Buick LeSabre. My question is, what is the best way to get rid of it? It is old and has a lot of miles on it. I suppose the dealer may take it off our hands for a very small trade-in amount -- at which point, they will probably just send it to the scrap yard. What are the odds of it getting properly recycled at that point? Should I first see if …

Hail the Cabs!

Hybrid taxis to hit the streets of New York City this fall Six different hybrid models will debut in New York City's taxi fleet this fall, thanks to a recent vote by the city's Taxi and Limousine Commission. Some commissioners had previously expressed reservations about the leg room (or lack thereof) in hybrids, but after test drives, one termed Toyota's Prius and Highlander "surprisingly roomy." The commission didn't have much of a choice -- Mayor Mike Bloomberg forced its hand by signing a bill last week that gave it 90 days to approve hybrids -- but commission chair Matthew Daus …
