Future of Electric Vehicles//Diet and Acne

Jim Motavalli joins us by phone from his home in Fairfield, Connecticut.  Jim is the author of a new book titled “High Voltage: The Fast Track to Plug In the Auto Industry” and helped us sort out some of the issues around EVs.  Mr. Motavalli is an auto journalist who writes for the New York Times, Car Talk, the Mother Nature Network and PlugInCars.com.  Jim has been covering the emerging electric vehicle industry for the last decade.   He reported that if he finds some extra money in his sofa cushions he’ll be buying a Tesla Roadster.   Rodale Press has donated some copies of “High Voltage” as premiums for new and renewing members.  Give us a call at 303-449-4885 and you’ll be reading Jim’s book faster than you can charge up your Nissan Leaf. (Motavalli interview starts at 4:39).

Shelley Schlender visited with Colorado State University Scientist and Paleolithic Lifestyle expert Loren Cordain to talk about acne prevention.    Cordain asserts that the best “prescription” for preventing acne is to eat the foods that have always helped traditional cultures be acne-free.  That means lots and lots of vegetables, along with some fruit.  Meanwhile, kick out modern foods–especially high glycemic foods . . . that means avoid sugary and starchy modern stuff  — you know, sodas, candy, bread and pasta.  Cordain also says to eliminate dairy.  (Cordain interview starts at 16:05).

Water Crisis // Maker Movement

Susan Moran has a telephone interview with Cynthia Barnett.   Cynthia is a journalist and author of Blue Revolution: Unmaking America’s Water Crisis.” She calls the U.S. one of the most “water-wasting places on the planet.” But in her book she also draws from positive examples of water conservation in the country to propose a new “water ethic.”  (start – 4:20).

Urban Parks // Pythons and Heart Disease

Today, November 1, we offer two features.

Central Park is also nature

Feature #1: Co-host Susan Moran interviews Jonathan Jarvis, director of the National Park Service, who discusses NPS’ quest to lure more people to urban parks, not just the iconic national parks such as Yellowstone and the Grand Canyon. These “threshold” experiences can lead people to appreciate, and help preserve, nature, including national parks. He also speaks of the NPS’ efforts to save the most threatened national parks, especially the Everglades.
Listen to the extended version of the interview here.

Feature #2: A python’s remarkable ability to quickly enlarge its heart and other organs during digestion is leading scientists at the University of Colorado in Boulder to uncover potential new therapies for heart disease. Their research was recently published in the journal Science. The new study also offers clues to how a special combination of fats found in normal foods just might end up as a powerful drug someday for helping a failing heart. How on Earth’s Shelley Schlender reports on the CU team’s research.

National Perspective on Municipalization//Science of Fall Colors

Tom McKinnon and Peter Asmus of Pike Research discuss electrical utility municipalization from a national perspective.  Peter adds an interesting statistic — the photovoltaic industry already has created more jobs than coal mining even though at present it produces much less power.

Shelley Schlender interviews Bill Hoch of Montana State University about why leaves turn colors in the fall.  Bill punches some holes in the conventional wisdom on the topic and notes that the color change is a critical step in the trees retaining important nutrients.

Post-Wild Nature//LED Lighting

Nature means something different to everyone. It’s a towering old-growth redwood forest to some.  Deep silent canyons to others. And urban community gardens to others. Defining what is “pristine nature” is even more dicey. Just ask conservation biologists trying to figure out the best ways to preserve ecosystems and their flora and fauna.
Co-host Susan Moran interviews Emma Marris, whose new book called “Rambunctious Garden: Saving Nature in a Post-wild World” sheds light on how notions of wilderness preservation are evolving to accommodate the ever-changing natural world, and our own role in it.

Tom McKinnon interviews Jeff Bisberg of Albeo Technologies about the new lighting revolution in solid-state LEDs.

Nitrogen pollution // Electric vehicles

On today’s show we offer two interview features.
Feature #1:

Gulf of Mexico hypoxic zone, caused by excess nutrients, mainly nitrogen from fertilizer

Last week the Environmental Protection Agency published a seminal report about nitrogen, which is an enormous environmental and public health problem that some scientists put on par with the carbon imbalance. Nitrogen is essential for all life, including ours, but excess nitrogen in the environment is turning out to be a predicament of crisis proportions. It kills fish, creates “dead zones” in places like the Gulf of Mexico, contaminates drinking water, and causes human illnesses.
Co-host Susan Moran interviews Dr. Hans Paerl, who has served on the EPA science advisory board and co-authored the report.   He’s a professor of Marine and Environmental Sciences, at the UNC-Chapel Hill Institute of Marine Sciences.

Tesla Roadster

Feature #2:
Our reliance on petroleum-fueled vehicles can be blamed, at least in part for a wide range of problems we face today, from local air pollution to global warming, the balance of payments deficit to political instability on a global scale.  One possible solution is to shift from a reliance on gasoline to the use of electricity for transportation.  Co-host Tom McKinnon interviews John Gartner, a senior analyst at Pike Research in Boulder, to discuss the electric vehicle outlook in the U.S.

Tech aspects of Boulder utility municipalization

In November Boulder will be asking the voters to approve the conversion of the electrical utility from one run by Xcel Energy to one run by the city.  While there are many, many political issues associated with this vote, there are technical ones as well.  We have on our show today Ken Regelson.  Ken is a sustainable energy consultant and member of the steering and tech modeling committees of RenewablesYes.org.  He holds a masters degree in electrical engineering.  And he tells us he’s available to speak on Boulder’s clean energy future at your neighborhood group, business, or at your next dinner party.

Cell Phone Safety

The World Health Organization has officially listed cells phones as a possible carcinogen. One expert who’s not surprised at the designation is University of Colorado, distinguished professor Frank Barnes. For decades, Barnes has cobbled together hard-to-find research dollars to study the biological effects of magnetic fields and radiation, including cell phone radiation. In 2008, he chaired a National Research Council report that called for more research into the health effects of all kinds of wireless technologies, including laptop computers, wireless phones, and cell phones. In today’s show, Frank Barnes talks with How on Earth’s Shelley Schlender about cell phone safety.
